Chapter 7. Security Profiles Operator


7.1. Security Profiles Operator overview

With the OpenShift Container Platform Security Profiles Operator (SPO), you can define seccomp and SELinux profiles as custom resources and keep them synchronized across every node in a namespace.

The SPO distributes seccomp and SELinux profile custom resources to each node and keeps them up to date when profiles change. You can also bind policies to pods and record workloads. See Additional resources for advanced tasks such as enabling the log enricher, configuring webhooks and metrics, or restricting profiles to a single namespace, and for advanced audit logging that correlates cluster users with actions during oc exec, oc rsh, and oc debug sessions.

7.2. Release notes for the Security Profiles Operator

The Security Profiles Operator provides a way to define secure computing (seccomp) and SELinux profiles as custom resources, synchronizing profiles to every node in a given namespace.

These release notes track the development of the Security Profiles Operator in OpenShift Container Platform.

7.2.1. Release notes for Security Profiles Operator 0.10.0

Release notes for Security Profiles Operator 0.10.0.

The following Red Hat Security Advisory (RHSA) is available for the Security Profiles Operator 0.10.0: RHSA-2026:2852 - OpenShift Security Profiles Operator update

7.2.1.1. Bug fixes

  • In some instances, using Security Profiles Operator (SPO) 0.9.0 with OpenShift Container Platform version 4.20 and above caused SPO to create the profilerecording resource but the workload would fail. Failure of the workload prevented the creation of the needed container for running the Operator. With the 0.10.0 release of SPO, the profilerecording resource is reliably created, therefore the needed container for running the Operator is reliably created (CMP-3537).
  • For version 0.9.0 of Security Profiles Operator (SPO), the spod pods would fail to run with the error message fsmount:fscontext:proc/: could not get mount id: operation not permitted. With the release of version 0.10.0, the spod pods run reliably. CMP-4007.
  • In releases of SPO 0.9.0 and earlier, there was a bug in syntax of the selinux usage. With this release of SPO, the change is from <policyName>_.process to <policyName>.process. The new syntax omits the _. Examples in the documentation now show this updated usage. CMP-4104

7.2.1.2. New features and enhancements

  • With the release of SPO v0.10.0, the Operator now supports Red Hat Enterprise Linux CoreOS (RHCOS) 10 containers. CMP-4033
  • In this release of the Security Profiles Operator, the Advanced Audit Logging Framework is available as a General Availability (GA) feature. The Advanced Audit Logging Framework uses the Audit JSON Log Enricher to capture and log terminal-based command activity in Red Hat Enterprise Linux CoreOS (RHCOS) containers, including oc rsh, oc exec, and oc debug commands. For more details, see Advanced Audit Logging Framework.

7.2.2. Release notes for Security Profiles Operator 0.9.0

Release notes for Security Profiles Operator 0.9.0.

The following Red Hat Bug Fix Advisory (RHBA) is available for the Security Profiles Operator 0.9.0: RHBA-2025:15655 - OpenShift Security Profiles Operator update

This update manages security profiles as cluster-wide resources rather than namespace resources. To update Security Profiles Operator to a version later than 0.8.6 requires manual migration. For migration instructions, see Security Profiles Operator 0.9.0 Update Migration Guide.

7.2.2.1. Bug fixes

  • Before this update, the spod pods could fail to start and enter into a CrashLoopBackOff state due to an error in parsing the semanage configuration file. A change to the RHEL 9 image naming convention beginning in OpenShift Container Platform 4.19 causes this issue. (OCPBUGS-55829)
  • Before this update, the Security Profiles Operator would fail to apply a RawSelinuxProfile to newly added nodes due to a reconciler type mismatch error. With this update, the Operator now correctly handles RawSelinuxProfile objects and applies policies to all nodes as expected. (OCPBUGS-33718)

7.2.3. Release notes for Security Profiles Operator 0.8.6

Release notes for Security Profiles Operator 0.8.6.

The following Red Hat Bug Fix Advisory (RHBA) is available for the Security Profiles Operator 0.8.6:

This update includes upgraded dependencies in underlying base images.

7.2.4. Release notes for Security Profiles Operator 0.8.5

Release notes for Security Profiles Operator 0.8.5.

The following Red Hat Bug Fix Advisory (RHBA) is available for the Security Profiles Operator 0.8.5:

7.2.4.1. Bug fixes

  • When attempting to install the Security Profiles Operator from the web console, the option to enable Operator-recommended cluster monitoring was unavailable for the namespace. With this update, you can now enabled Operator-recommend cluster monitoring in the namespace. (OCPBUGS-37794)
  • Before this update, the Security Profiles Operator would intermittently be not visible in the OperatorHub, which caused limited access to install the Operator through the web console. With this update, the Security Profiles Operator is present in the OperatorHub.

7.2.5. Release notes for Security Profiles Operator 0.8.4

Release notes for Security Profiles Operator 0.8.4.

The following Red Hat Bug Fix Advisory (RHBA) is available for the Security Profiles Operator 0.8.4:

7.2.5.1. New features and enhancements

7.2.6. Release notes for Security Profiles Operator 0.8.2

Release notes for Security Profiles Operator 0.8.2.

The following Red Hat Bug Fix Advisory (RHBA) is available for the Security Profiles Operator 0.8.2:

7.2.6.1. Bug fixes

  • Before this update, SELinuxProfile objects did not inherit custom attributes from the same namespace. With this update, SELinuxProfile object attributes inherit from the same namespace as expected. (OCPBUGS-17164)
  • Before this update, RawSELinuxProfile objects would hang during the creation process and would not reach an Installed state. With this update, the operator creates RawSELinuxProfile objects successfully. (OCPBUGS-19744)
  • Before this update, patching the enableLogEnricher to true would cause the seccompProfile log-enricher-trace pods to remain in a Pending state. With this update, log-enricher-trace pods reach an Installed state as expected. (OCPBUGS-22182)
  • Before this update, the Security Profiles Operator generated high cardinality metrics, causing Prometheus pods using high amounts of memory. With this update, the following metrics will no longer apply in the Security Profiles Operator namespace:

    • rest_client_request_duration_seconds
    • rest_client_request_size_bytes
    • rest_client_response_size_bytes

      (OCPBUGS-22406)

7.2.7. Release notes for Security Profiles Operator 0.8.0

Release notes for Security Profiles Operator 0.8.0.

The following Red Hat Bug Fix Advisory (RHBA) is available for the Security Profiles Operator 0.8.0:

7.2.7.1. Bug fixes

  • Before this update, while trying to install Security Profiles Operator in a disconnected cluster, the secure hash algorithms (SHAs) provided were wrong due to an SHA relabeling issue. With this update, the secure hash algorithms work consistently with disconnected environments. (OCPBUGS-14404)

7.2.8. Release notes for Security Profiles Operator 0.7.1

Release notes for Security Profiles Operator 0.7.1.

The following Red Hat Security Advisory (RHSA) is available for the Security Profiles Operator 0.7.1:

7.2.8.1. New features and enhancements

  • Security Profiles Operator (SPO) now automatically selects the appropriate selinuxd image for RHEL 8- and 9-based Red Hat Enterprise Linux CoreOS (RHCOS) systems.

    Important

    Users that mirror images for disconnected environments must mirror both selinuxd images provided by the Security Profiles Operator.

  • You can now enable memory optimization inside of an spod daemon. For more information, see Enabling memory optimization in the spod daemon.

    Note

    SPO memory optimization is not enabled by default.

  • The daemon resource requirements are now configurable. For more information, see Customizing daemon resource requirements.
  • The priority class name is now configurable in the spod configuration. For more information, see Setting a custom priority class name for the spod daemon pod.

7.2.8.2. Deprecated and removed features

  • The default nginx-1.19.1 seccomp profile is now removed from the Security Profiles Operator deployment.

7.2.8.3. Bug fixes

  • Before this update, a Security Profiles Operator (SPO) SELinux policy did not inherit low-level policy definitions from the container template. If you selected another template, such as net_container, the policy would not work because it required low-level policy definitions that only existed in the container template. This issue occurred when the SPO SELinux policy attempted to translate SELinux policies from the SPO custom format to the Common Intermediate Language (CIL) format. With this update, the container template appends to any SELinux policies that require translation from SPO to CIL. Additionally, the SPO SELinux policy can inherit low-level policy definitions from any supported policy template. (OCPBUGS-12879)

7.2.8.4. Known issue

  • When uninstalling the Security Profiles Operator, the MutatingWebhookConfiguration object is not deleted and must be manually removed. As a workaround, delete the MutatingWebhookConfiguration object after uninstalling the Security Profiles Operator. For these steps, see Uninstalling the Security Profiles Operator. (OCPBUGS-4687)

7.2.9. Release notes for Security Profiles Operator 0.5.2

The following Red Hat Bug Fix Advisory (RHBA) is available for the Security Profiles Operator 0.5.2:

This update addresses a CVE in an underlying dependency.

7.2.9.1. Known issue

  • When uninstalling the Security Profiles Operator, the MutatingWebhookConfiguration object is not deleted and must be manually removed. As a workaround, delete the MutatingWebhookConfiguration object after uninstalling the Security Profiles Operator. For these steps, see Uninstalling the Security Profiles Operator. (OCPBUGS-4687)

7.2.10. Release notes for Security Profiles Operator 0.5.0

Release notes for Security Profiles Operator 0.5.0.

The following Red Hat Bug Fix Advisory (RHBA) is available for the Security Profiles Operator 0.5.0:

7.2.10.1. Known issue

  • When uninstalling the Security Profiles Operator, the MutatingWebhookConfiguration object is not deleted and must be manually removed. As a workaround, delete the MutatingWebhookConfiguration object after uninstalling the Security Profiles Operator. For these steps, see Uninstalling the Security Profiles Operator. (OCPBUGS-4687)

7.3. Security Profiles Operator support

The Security Profiles Operator is a "Rolling Stream" Operator, meaning updates are available asynchronously of OpenShift Container Platform releases.

7.3.1. Getting support

If you experience difficulty with a procedure described in this documentation, or with OpenShift Container Platform in general, visit the Red Hat Customer Portal.

From the Red Hat Customer Portal, you can:

  • Search or browse through the Red Hat Knowledgebase of articles and solutions relating to Red Hat products.
  • Submit a support case to Red Hat Support.
  • Access other product documentation.

To identify issues with your cluster, you can use Red Hat Lightspeed in OpenShift Cluster Manager. Red Hat Lightspeed provides details about issues and, if available, information on how to solve a problem.

To suggest improvements or report errors, provide specific details such as the section name and OpenShift Container Platform version.

7.4. Understanding the Security Profiles Operator

OpenShift Container Platform administrators can use the Security Profiles Operator to define increased security measures in clusters.

Important

The Security Profiles Operator supports only Red Hat Enterprise Linux CoreOS (RHCOS) worker nodes. Red Hat Enterprise Linux (RHEL) nodes are not supported.

7.4.1. About security profiles

Security profiles limit what containers can do on a node, so you can reduce the attack surface of workloads in your cluster.

Seccomp security profiles list the syscalls a process can make. Permissions are broader than SELinux, enabling users to restrict operations system-wide, such as write.

SELinux security profiles provide a label-based system that restricts the access and usage of processes, applications, or files in a system. All files in an environment have labels that define permissions. SELinux profiles can define access within a given structure, such as directories.

7.5. Enabling the Security Profiles Operator

Before you can use the Security Profiles Operator, you must ensure the Operator is deployed in the cluster.

Important

All cluster nodes must have the same release version in order for this Operator to function properly. As an example, for nodes running RHCOS, all nodes must have the same RHCOS version.

Important

The Security Profiles Operator supports only Red Hat Enterprise Linux CoreOS (RHCOS) worker nodes. Red Hat Enterprise Linux (RHEL) nodes are not supported.

Important

The Security Profiles Operator supports x86_64 and ppc64le architecture.

7.5.1. Installing the Security Profiles Operator

You can use the OpenShift Container Platform web console to install the Security Profiles Operator. This installs the Security Profiles Operator into the openshift-security-profiles namespace by default. You can also verify correct installation by using the OpenShift Container Platform web console.

Prerequisites

  • You must have access to the web console as a user with cluster-admin privileges.

Procedure

  1. In the OpenShift Container Platform web console, navigate to Ecosystem Software Catalog.
  2. Search for the Security Profiles Operator, then click Install.
  3. Keep the default selection of Installation mode and namespace to ensure that the Operator will be installed to the openshift-security-profiles namespace.
  4. Click Install.

Verification

To confirm that the installation is successful:

  1. Navigate to the Ecosystem Installed Operators page.
  2. Check that the Security Profiles Operator is installed in the openshift-security-profiles namespace and its status is Succeeded.

If the Operator is not installed successfully:

  1. Navigate to the Ecosystem Installed Operators page and inspect the Status column for any errors or failures.
  2. Navigate to the Workloads Pods page and check the logs in any pods in the openshift-security-profiles project that are reporting issues.

7.5.2. Installing the Security Profiles Operator using the CLI

You can install the OpenShift Container Platform Security Profiles Operator by using the command line interface.

Prerequisites

  • You must have cluster-admin privileges.

Procedure

  1. Define a Namespace object:

    Example namespace-object.yaml

    apiVersion: v1
    kind: Namespace
    metadata:
        name: openshift-security-profiles
    labels:
      openshift.io/cluster-monitoring: "true"

  2. Create the Namespace object:

    $ oc create -f namespace-object.yaml
  3. Define an OperatorGroup object:

    Example operator-group-object.yaml

    apiVersion: operators.coreos.com/v1
    kind: OperatorGroup
    metadata:
      name: security-profiles-operator
      namespace: openshift-security-profiles

  4. Create the OperatorGroup object:

    $ oc create -f operator-group-object.yaml
  5. Define a Subscription object:

    Example subscription-object.yaml

    apiVersion: operators.coreos.com/v1alpha1
    kind: Subscription
    metadata:
      name: security-profiles-operator-sub
      namespace: openshift-security-profiles
    spec:
      channel: release-alpha-rhel-8
      installPlanApproval: Automatic
      name: security-profiles-operator
      source: redhat-operators
      sourceNamespace: openshift-marketplace

  6. Create the Subscription object:

    $ oc create -f subscription-object.yaml
    Note

    If you are setting the global scheduler feature and enable defaultNodeSelector, you must create the namespace manually and update the annotations of the openshift-security-profiles namespace, or the namespace where the Security Profiles Operator was installed, with openshift.io/node-selector: “”. This removes the default node selector and prevents deployment failures.

Verification

  1. Verify the installation succeeded by inspecting the following CSV file:

    $ oc get csv -n openshift-security-profiles
  2. Verify that the Security Profiles Operator is operational by running the following command:

    $ oc get deploy -n openshift-security-profiles

7.5.3. Configuring logging verbosity

The Security Profiles Operator supports the default logging verbosity of 0 and an enhanced verbosity of 1.

Procedure

  • To enable enhanced logging verbosity, patch the spod configuration and adjust the value by running the following command:

    $ oc -n openshift-security-profiles patch spod \
        spod --type=merge -p '{"spec":{"verbosity":1}}'

    Example output

    securityprofilesoperatordaemon.security-profiles-operator.x-k8s.io/spod patched

7.6. Managing seccomp profiles

Create and manage seccomp profiles and bind them to workloads.

Important

The Security Profiles Operator supports only Red Hat Enterprise Linux CoreOS (RHCOS) worker nodes. Red Hat Enterprise Linux (RHEL) nodes are not supported.

7.6.1. Creating seccomp profiles

Use the SeccompProfile object to create seccomp profiles.

SeccompProfile objects can restrict syscalls within a container, limiting the access of your application.

Procedure

  1. Create a project by running the following command:

    $ oc new-project my-namespace
  2. Create the SeccompProfile object:

    apiVersion: security-profiles-operator.x-k8s.io/v1beta1
    kind: SeccompProfile
    metadata:
      name: profile1
    spec:
      defaultAction: SCMP_ACT_LOG

    The seccomp profile will be saved in /var/lib/kubelet/seccomp/operator/<namespace>/<name>.json.

    An init container creates the root directory of the Security Profiles Operator to run the Operator without root group or user ID privileges. A symbolic link is created from the rootless profile storage /var/lib/openshift-security-profiles to the default seccomp root path inside of the kubelet root /var/lib/kubelet/seccomp/operator.

7.6.2. Apply seccomp profiles to a pod

To enforce a recorded or custom seccomp profile on a workload, create a pod that references the profile in its security context.

Procedure

  1. Create a pod object that defines a securityContext:

    apiVersion: v1
    kind: Pod
    metadata:
      name: test-pod
    spec:
      securityContext:
        runAsNonRoot: true
        seccompProfile:
          type: Localhost
          localhostProfile: operator/profile1.json
      containers:
        - name: test-container
          image: quay.io/security-profiles-operator/test-nginx-unprivileged:1.21
          securityContext:
            allowPrivilegeEscalation: false
            capabilities:
              drop: [ALL]
  2. View the profile path of the seccompProfile.localhostProfile attribute by running the following command:

    $ oc get seccompprofile profile1 --output wide

    Example output

    NAME       STATUS     AGE   SECCOMPPROFILE.LOCALHOSTPROFILE
    profile1   Installed  14s   operator/profile1.json

  3. View the path to the localhost profile by running the following command:

    $ oc get sp profile1 --output=jsonpath='{.status.localhostProfile}'

    Example output

    operator/profile1.json

  4. Apply the localhostProfile output to the patch file:

    spec:
      template:
        spec:
          securityContext:
            seccompProfile:
              type: Localhost
              localhostProfile: operator/profile1.json
  5. Apply the profile to any other workload, such as a Deployment object, by running the following command:

    $ oc -n my-namespace patch deployment myapp --patch-file patch.yaml --type=merge

    Example output

    deployment.apps/myapp patched

Verification

  • Confirm the profile was applied correctly by running the following command:

    $ oc -n my-namespace get deployment myapp --output=jsonpath='{.spec.template.spec.securityContext}' | jq .

    Example output

    {
      "seccompProfile": {
        "localhostProfile": "operator/profile1.json",
        "type": "localhost"
      }
    }

7.6.2.1. Binding workloads to profiles with ProfileBindings

You can use the ProfileBinding resource to bind a security profile to the SecurityContext of a container.

Procedure

  1. To bind a pod that uses a quay.io/security-profiles-operator/test-nginx-unprivileged:1.21 image to the example SeccompProfile profile, create a ProfileBinding object in the same namespace with the pod and the SeccompProfile objects:

    apiVersion: security-profiles-operator.x-k8s.io/v1alpha1
    kind: ProfileBinding
    metadata:
      namespace: my-namespace
      name: nginx-binding
    spec:
      profileRef:
        kind: SeccompProfile
        name: profile
      image: quay.io/security-profiles-operator/test-nginx-unprivileged:1.21

    where:

    spec.profileRef.kind
    Specifies the kind of the profile.
    spec.profileRef.name
    Specifies the name of the profile.
    spec.image
    Allows you to enable a default security profile by using a wildcard in the image attribute: image: "*"
    Important

    Using the image: "*" wildcard attribute binds all new pods with a default security profile in a given namespace.

  2. Label the namespace with enable-binding=true by running the following command:

    $ oc label ns my-namespace spo.x-k8s.io/enable-binding=true
  3. Define a pod named test-pod.yaml:

    apiVersion: v1
    kind: Pod
    metadata:
      name: test-pod
    spec:
      containers:
      - name: test-container
        image: quay.io/security-profiles-operator/test-nginx-unprivileged:1.21
  4. Create the pod:

    $ oc create -f test-pod.yaml
    Note

    If the pod already exists, you must re-create the pod for the binding to work properly.

Verification

  • Confirm the pod inherits the ProfileBinding by running the following command:

    $ oc get pod test-pod -o jsonpath='{.spec.containers[*].securityContext.seccompProfile}'

    Example output

    {"localhostProfile":"operator/profile.json","type":"Localhost"}

7.6.3. Record profiles from workloads

The Security Profiles Operator can record system calls with ProfileRecording objects to create baseline profiles for applications.

When using the log enricher for recording seccomp profiles, verify the log enricher feature is enabled. See Additional resources for more information.

Note

A container with privileged: true security context restraints prevents log-based recording. Privileged containers are not subject to seccomp policies, and log-based recording makes use of a special seccomp profile to record events.

Procedure

  1. Create a project by running the following command:

    $ oc new-project my-namespace
  2. Label the namespace with enable-recording=true by running the following command:

    $ oc label ns my-namespace spo.x-k8s.io/enable-recording=true
  3. Create a ProfileRecording object containing a recorder: logs variable:

    apiVersion: security-profiles-operator.x-k8s.io/v1alpha1
    kind: ProfileRecording
    metadata:
      namespace: my-namespace
      name: test-recording
    spec:
      kind: SeccompProfile
      recorder: logs
      podSelector:
        matchLabels:
          app: my-app
  4. Create a workload to record:

    apiVersion: v1
    kind: Pod
    metadata:
      namespace: my-namespace
      name: my-pod
      labels:
        app: my-app
    spec:
      securityContext:
        runAsNonRoot: true
        seccompProfile:
          type: RuntimeDefault
      containers:
        - name: nginx
          image: quay.io/security-profiles-operator/test-nginx-unprivileged:1.21
          ports:
            - containerPort: 8080
          securityContext:
            allowPrivilegeEscalation: false
            capabilities:
              drop: [ALL]
        - name: redis
          image: quay.io/security-profiles-operator/redis:6.2.1
          securityContext:
            allowPrivilegeEscalation: false
            capabilities:
              drop: [ALL]
  5. Confirm the pod is in a Running state by entering the following command:

    $ oc -n my-namespace get pods

    Example output

    NAME     READY   STATUS    RESTARTS   AGE
    my-pod   2/2     Running   0          18s

  6. Confirm the enricher indicates that it receives audit logs for those containers:

    $ oc -n openshift-security-profiles logs --since=1m --selector name=spod -c log-enricher

    Example output

    I0523 14:19:08.747313  430694 enricher.go:445] log-enricher "msg"="audit" "container"="redis" "executable"="/usr/local/bin/redis-server" "namespace"="my-namespace" "node"="xiyuan-23-5g2q9-worker-eastus2-6rpgf" "pid"=656802 "pod"="my-pod" "syscallID"=0 "syscallName"="read" "timestamp"="1684851548.745:207179" "type"="seccomp"

Verification

  1. Remove the pod:

    $ oc -n my-namespace delete pod my-pod
  2. Confirm the Security Profiles Operator reconciles the two seccomp profiles:

    $ oc get seccompprofiles -lspo.x-k8s.io/recording-id=test-recording

    Example output for seccomp profile

    NAME                   STATUS      AGE
    test-recording-nginx   Installed   2m48s
    test-recording-redis   Installed   2m48s

7.6.3.1. Merge per-container profile instances

To reuse one recorded profile when deploying applications with a ReplicaSet or Deployment, configure the Security Profiles Operator to merge per-container profile instances into a single profile instead of keeping a separate profile for each container.

Procedure

  1. Edit a ProfileRecording object to include a mergeStrategy: containers variable:

    apiVersion: security-profiles-operator.x-k8s.io/v1alpha1
    kind: ProfileRecording
    metadata:
      # The name of the Recording is the same as the resulting SeccompProfile CRD
      # after reconciliation.
      name: test-recording
      namespace: my-namespace
    spec:
      kind: SeccompProfile
      recorder: logs
      mergeStrategy: containers
      podSelector:
        matchLabels:
          app: sp-record
  2. Label the namespace by running the following command:

    $ oc label ns my-namespace security.openshift.io/scc.podSecurityLabelSync=false pod-security.kubernetes.io/enforce=privileged pod-security.kubernetes.io/audit=privileged pod-security.kubernetes.io/warn=privileged --overwrite=true
  3. Create the workload with the following YAML:

    apiVersion: apps/v1
    kind: Deployment
    metadata:
      name: nginx-deploy
      namespace: my-namespace
    spec:
      replicas: 3
      selector:
        matchLabels:
          app: sp-record
      template:
        metadata:
          labels:
            app: sp-record
        spec:
          serviceAccountName: spo-record-sa
          containers:
          - name: nginx-record
            image: quay.io/security-profiles-operator/test-nginx-unprivileged:1.21
            ports:
            - containerPort: 8080
  4. To record the individual profiles, delete the deployment by running the following command:

    $ oc delete deployment nginx-deploy -n my-namespace
  5. To merge the profiles, delete the profile recording by running the following command:

    $ oc delete profilerecording test-recording -n my-namespace
  6. To start the merge operation and generate the results profile, run the following command:

    $ oc get seccompprofiles -lspo.x-k8s.io/recording-id=test-recording -n my-namespace

    Example output for seccomp profile

    NAME                          STATUS       AGE
    test-recording-nginx-record   Installed    55s

  7. To view the permissions used by any of the containers, run the following command:

    $ oc get seccompprofiles test-recording-nginx-record -o yaml

7.7. Managing SELinux profiles

To control what namespaced workloads can access on RHCOS nodes, use the Security Profiles Operator to create SELinux profiles, bind them to pods, and record policies from running applications.

Important

The Security Profiles Operator supports only Red Hat Enterprise Linux CoreOS (RHCOS) worker nodes. Red Hat Enterprise Linux (RHEL) nodes are not supported.

7.7.1. Creating SELinux profiles

Use the SelinuxProfile object to create SELinux profiles.

The SelinuxProfile object has several features that allow for better security hardening and readability:

  • Restricts the profiles to inherit from to the current namespace or a system-wide profile. Because there are typically many profiles installed on the system, but only a subset should be used by cluster workloads, the inheritable system profiles are listed in the spod instance in spec.selinuxOptions.allowedSystemProfiles.
  • Performs basic validation of the permissions, classes and labels.
  • Adds a new keyword @self that describes the process using the policy. This allows reusing a policy between workloads and namespaces easily, as the usage of the policy is based on the name and namespace.
  • Adds features for better security hardening and readability compared to writing a profile directly in the SELinux CIL language.

Procedure

  1. Create a project by running the following command:

    $ oc new-project nginx-deploy
  2. Create a policy that can be used with a non-privileged workload by creating the following SelinuxProfile object:

    apiVersion: security-profiles-operator.x-k8s.io/v1alpha2
    kind: SelinuxProfile
    metadata:
      name: nginx-secure
    spec:
      allow:
        '@self':
          tcp_socket:
          - listen
        http_cache_port_t:
          tcp_socket:
          - name_bind
        node_t:
          tcp_socket:
          - node_bind
      inherit:
      - kind: System
        name: container
  3. Wait for selinuxd to install the policy by running the following command:

    $ oc wait --for=condition=ready selinuxprofile nginx-secure

    Example output

    selinuxprofile.security-profiles-operator.x-k8s.io/nginx-secure condition met

    The policies are placed into an emptyDir in the container owned by the Security Profiles Operator. The policies are saved in Common Intermediate Language (CIL) format in /etc/selinux.d/<name>_<namespace>.cil.

  4. Access the pod by running the following command:

    $ oc -n openshift-security-profiles rsh -c selinuxd ds/spod

Verification

  1. View the file contents with cat by running the following command:

    $ cat /etc/selinux.d/nginx-secure.cil

    Example output

    (block nginx-secure
    (blockinherit container)
    (allow process nginx-secure.process ( tcp_socket ( listen )))
    (allow process http_cache_port_t ( tcp_socket ( name_bind )))
    (allow process node_t ( tcp_socket ( node_bind )))
    )

  2. Verify that a policy has been installed by running the following command:

    $ semodule -l | grep nginx-secure

    Example output

    nginx-secure

7.7.2. Apply SELinux profiles to a pod

To enforce a recorded or custom SELinux profile on a workload, create a pod that references the profile in its security context.

For SELinux profiles, the namespace must be labeled to allow privileged workloads.

Procedure

  1. Apply the scc.podSecurityLabelSync=false label to the nginx-deploy namespace by running the following command:

    $ oc label ns nginx-deploy security.openshift.io/scc.podSecurityLabelSync=false
  2. Apply the privileged label to the nginx-deploy namespace by running the following command:

    $ oc label ns nginx-deploy --overwrite=true pod-security.kubernetes.io/enforce=privileged
  3. Obtain the SELinux profile usage string by running the following command:

    $ oc get selinuxprofile.security-profiles-operator.x-k8s.io/nginx-secure -ojsonpath='{.status.usage}'

    Example output

    nginx-secure.process

  4. Apply the output string in the workload manifest in the .spec.containers[].securityContext.seLinuxOptions attribute:

    apiVersion: v1
    kind: Pod
    metadata:
      name: nginx-secure
      namespace: nginx-deploy
    spec:
      securityContext:
        runAsNonRoot: true
        seccompProfile:
          type: RuntimeDefault
      containers:
        - image: nginxinc/nginx-unprivileged:1.21
          name: nginx
          securityContext:
            allowPrivilegeEscalation: false
            capabilities:
              drop: [ALL]
            seLinuxOptions:
              # NOTE: This uses an appropriate SELinux type
              type: nginx-secure.process
    Important

    The SELinux type must exist before creating the workload.

7.7.2.1. Apply SELinux log policies

To log policy violations or AVC denials, set the SElinuxProfile profile to permissive.

Important

This procedure defines logging policies. It does not set enforcement policies.

Procedure

  • Add permissive: true to an SElinuxProfile:

    apiVersion: security-profiles-operator.x-k8s.io/v1alpha2
    kind: SelinuxProfile
    metadata:
      name: nginx-secure
    spec:
      permissive: true

7.7.2.2. Binding workloads to profiles with ProfileBindings

You can use the ProfileBinding resource to bind a security profile to the SecurityContext of a container.

Procedure

  1. To bind a pod that uses a quay.io/security-profiles-operator/test-nginx-unprivileged:1.21 image to the example SelinuxProfile profile, create a ProfileBinding object in the same namespace with the pod and the SelinuxProfile objects:

    apiVersion: security-profiles-operator.x-k8s.io/v1alpha1
    kind: ProfileBinding
    metadata:
      namespace: my-namespace
      name: nginx-binding
    spec:
      profileRef:
        kind: SelinuxProfile
        name: profile
      image: quay.io/security-profiles-operator/test-nginx-unprivileged:1.21

    where:

    spec.profileRef.kind
    Specifies the kind of the profile.
    spec.profileRef.name
    Specifies the name of the profile.
    spec.image
    Allows you to enable a default security profile by using a wildcard in the image attribute: image: "*"
    Important

    Using the image: "*" wildcard attribute binds all new pods with a default security profile in a given namespace.

  2. Label the namespace with enable-binding=true by running the following command:

    $ oc label ns my-namespace spo.x-k8s.io/enable-binding=true
  3. Define a pod named test-pod.yaml:

    apiVersion: v1
    kind: Pod
    metadata:
      name: test-pod
    spec:
      containers:
      - name: test-container
        image: quay.io/security-profiles-operator/test-nginx-unprivileged:1.21
  4. Create the pod:

    $ oc create -f test-pod.yaml
    Note

    If the pod already exists, you must re-create the pod for the binding to work properly.

Verification

  • Confirm the pod inherits the ProfileBinding by running the following command:

    $ oc get pod test-pod -o jsonpath='{.spec.containers[*].securityContext.seLinuxOptions.type}'

    Example output

    profile.process

7.7.2.3. Replicate controllers and SecurityContextConstraints

Deploy SELinux policies for replicating controllers such as deployments or daemon sets so the pods those controllers create can use custom SELinux policies.

Pods that the controllers create do not run with the identity of the user who creates the workload. Unless you select a ServiceAccount, the pods might use a restricted SecurityContextConstraints (SCC) object that does not allow custom security policies.

Procedure

  1. Create a project by running the following command:

    $ oc new-project nginx-secure
  2. Create the following RoleBinding object to allow SELinux policies to be used in the nginx-secure namespace:

    kind: RoleBinding
    apiVersion: rbac.authorization.k8s.io/v1
    metadata:
      name: spo-nginx
      namespace: nginx-secure
    subjects:
    - kind: ServiceAccount
      name: spo-deploy-test
    roleRef:
      kind: Role
      name: spo-nginx
      apiGroup: rbac.authorization.k8s.io
  3. Create the Role object:

    apiVersion: rbac.authorization.k8s.io/v1
    kind: Role
    metadata:
      creationTimestamp: null
      name: spo-nginx
      namespace: nginx-secure
    rules:
    - apiGroups:
      - security.openshift.io
      resources:
      - securitycontextconstraints
      resourceNames:
      - privileged
      verbs:
      - use
  4. Create the ServiceAccount object:

    apiVersion: v1
    kind: ServiceAccount
    metadata:
      creationTimestamp: null
      name: spo-deploy-test
      namespace: nginx-secure
  5. Create the Deployment object:

    apiVersion: apps/v1
    kind: Deployment
    metadata:
      name: selinux-test
      namespace: nginx-secure
      metadata:
        labels:
          app: selinux-test
    spec:
      replicas: 3
      selector:
        matchLabels:
          app: selinux-test
      template:
        metadata:
          labels:
            app: selinux-test
        spec:
          serviceAccountName: spo-deploy-test
          securityContext:
            seLinuxOptions:
              type: nginx-secure.process
          containers:
          - name: nginx-unpriv
            image: quay.io/security-profiles-operator/test-nginx-unprivileged:1.21
            ports:
            - containerPort: 8080

    The spec.template.spec.securityContext.seLinuxOptions.type must exist before the Deployment is created.

    Note

    The SELinux type is not specified in the workload and is handled by the SCC. When the pods are created by the deployment and the ReplicaSet, the pods will run with the appropriate profile.

    Ensure that your SCC is usable by only the correct service account. Refer to Additional resources for more information.

7.7.3. Record profiles from workloads

The Security Profiles Operator can record system calls with ProfileRecording objects to create baseline profiles for applications.

When using the log enricher for recording SELinux profiles, verify the log enricher feature is enabled. See Additional resources for more information.

Note

A container with privileged: true security context restraints prevents log-based recording. Privileged containers are not subject to SELinux policies, and log-based recording makes use of a special SELinux profile to record events.

Procedure

  1. Create a project by running the following command:

    $ oc new-project my-namespace
  2. Label the namespace with enable-recording=true by running the following command:

    $ oc label ns my-namespace spo.x-k8s.io/enable-recording=true
  3. Create a ProfileRecording object containing a recorder: logs variable:

    apiVersion: security-profiles-operator.x-k8s.io/v1alpha1
    kind: ProfileRecording
    metadata:
      namespace: my-namespace
      name: test-recording
    spec:
      kind: SelinuxProfile
      recorder: logs
      podSelector:
        matchLabels:
          app: my-app
  4. Create a workload to record:

    apiVersion: v1
    kind: Pod
    metadata:
      namespace: my-namespace
      name: my-pod
      labels:
        app: my-app
    spec:
      securityContext:
        runAsNonRoot: true
        seccompProfile:
          type: RuntimeDefault
      containers:
        - name: nginx
          image: quay.io/security-profiles-operator/test-nginx-unprivileged:1.21
          ports:
            - containerPort: 8080
          securityContext:
            allowPrivilegeEscalation: false
            capabilities:
              drop: [ALL]
        - name: redis
          image: quay.io/security-profiles-operator/redis:6.2.1
          securityContext:
            allowPrivilegeEscalation: false
            capabilities:
              drop: [ALL]
  5. Confirm the pod is in a Running state by entering the following command:

    $ oc -n my-namespace get pods

    Example output

    NAME     READY   STATUS    RESTARTS   AGE
    my-pod   2/2     Running   0          18s

  6. Confirm the enricher indicates that it receives audit logs for those containers:

    $ oc -n openshift-security-profiles logs --since=1m --selector name=spod -c log-enricher

    Example output

    I0517 13:55:36.383187  348295 enricher.go:376] log-enricher "msg"="audit" "container"="redis" "namespace"="my-namespace" "node"="ip-10-0-189-53.us-east-2.compute.internal" "perm"="name_bind" "pod"="my-pod" "profile"="test-recording_redis_6kmrb_1684331729" "scontext"="system_u:system_r:selinuxrecording.process:s0:c4,c27" "tclass"="tcp_socket" "tcontext"="system_u:object_r:redis_port_t:s0" "timestamp"="1684331735.105:273965" "type"="selinux"

Verification

  1. Remove the pod:

    $ oc -n my-namespace delete pod my-pod
  2. Confirm the Security Profiles Operator reconciles the two SELinux profiles:

    $ oc get selinuxprofiles -lspo.x-k8s.io/recording-id=test-recording

    Example output for SELinux profile

    NAME                   USAGE                                 STATE
    test-recording-nginx   test-recording-nginx.process   Installed
    test-recording-redis   test-recording-redis.process   Installed

7.7.3.1. Merge per-container profile instances

To reuse one recorded profile when deploying applications with a ReplicaSet or Deployment, configure the Security Profiles Operator to merge per-container profile instances into a single profile instead of keeping a separate profile for each container.

Procedure

  1. Edit a ProfileRecording object to include a mergeStrategy: containers variable:

    apiVersion: security-profiles-operator.x-k8s.io/v1alpha1
    kind: ProfileRecording
    metadata:
      # The name of the Recording is the same as the resulting SelinuxProfile CRD
      # after reconciliation.
      name: test-recording
      namespace: my-namespace
    spec:
      kind: SelinuxProfile
      recorder: logs
      mergeStrategy: containers
      podSelector:
        matchLabels:
          app: sp-record
  2. Label the namespace by running the following command:

    $ oc label ns my-namespace security.openshift.io/scc.podSecurityLabelSync=false pod-security.kubernetes.io/enforce=privileged pod-security.kubernetes.io/audit=privileged pod-security.kubernetes.io/warn=privileged --overwrite=true
  3. Create the workload with the following YAML:

    apiVersion: apps/v1
    kind: Deployment
    metadata:
      name: nginx-deploy
      namespace: my-namespace
    spec:
      replicas: 3
      selector:
        matchLabels:
          app: sp-record
      template:
        metadata:
          labels:
            app: sp-record
        spec:
          serviceAccountName: spo-record-sa
          containers:
          - name: nginx-record
            image: quay.io/security-profiles-operator/test-nginx-unprivileged:1.21
            ports:
            - containerPort: 8080
  4. To record the individual profiles, delete the deployment by running the following command:

    $ oc delete deployment nginx-deploy -n my-namespace
  5. To merge the profiles, delete the profile recording by running the following command:

    $ oc delete profilerecording test-recording -n my-namespace
  6. To start the merge operation and generate the results profile, run the following command:

    $ oc get selinuxprofiles -lspo.x-k8s.io/recording-id=test-recording -n my-namespace

    Example output for SELinux profile

    NAME                          USAGE                            STATE
    test-recording-nginx-record   test-recording-nginx-record.process   Installed

  7. To view the permissions used by any of the containers, run the following command:

    $ oc get selinuxprofiles test-recording-nginx-record -o yaml

7.7.3.2. About seLinuxContext: RunAsAny

To record SELinux policies, a webhook injects a permissive SELinux type so the pod logs AVC denials while recording.

The SELinux type makes the pod run in permissive mode, logging all the AVC denials into audit.log. By default, a workload is not allowed to run with a custom SELinux policy, but uses an automatically generated type.

To record a workload, the workload must use a service account that has permissions to use an SCC that allows the webhook to inject the permissive SELinux type. The privileged SCC contains seLinuxContext: RunAsAny.

In addition, the namespace must be labeled with pod-security.kubernetes.io/enforce: privileged if your cluster enables Pod Security Admission, because only the privileged Pod Security Standard allows using a custom SELinux policy.

7.8. Advanced Security Profiles Operator tasks

You can use advanced Security Profiles Operator tasks to enable metrics, configure webhooks, or restrict syscalls.

7.8.1. Restrict the allowed syscalls in seccomp profiles

The Security Profiles Operator does not restrict syscalls in seccomp profiles by default. You can define the list of allowed syscalls in the spod configuration.

Important

The Operator will install only the seccomp profiles, which have a subset of syscalls defined into the allowed list. All profiles not complying with this ruleset are rejected.

When the list of allowed syscalls is modified in the spod configuration, the Operator will identify the already installed profiles which are noncompliant and remove them automatically.

Procedure

  • To define the list of allowedSyscalls, adjust the spec parameter by running the following command:

    $ oc -n openshift-security-profiles patch spod spod --type merge \
        -p '{"spec":{"allowedSyscalls": ["exit", "exit_group", "futex", "nanosleep"]}}'

7.8.2. Base syscalls for a container runtime

You can use the baseProfileName attribute to establish the minimum required syscalls for a given runtime to start a container.

Procedure

  • Edit the SeccompProfile kind object and add baseProfileName: runc-v1.0.0 to the spec field:

    apiVersion: security-profiles-operator.x-k8s.io/v1beta1
    kind: SeccompProfile
    metadata:
      name: example-name
    spec:
      defaultAction: SCMP_ACT_ERRNO
      baseProfileName: runc-v1.0.0
      syscalls:
        - action: SCMP_ACT_ALLOW
          names:
            - exit_group

7.8.3. Enabling memory optimization in the spod daemon

The controller running inside of spod daemon process watches all pods available in the cluster when profile recording is enabled. This can lead to very high memory usage in large clusters, resulting in the spod daemon running out of memory or crashing.

To prevent crashes, the spod daemon can be configured to only load the pods labeled for profile recording into the cache memory.

Note

SPO memory optimization is not enabled by default.

Procedure

  1. Enable memory optimization by running the following command:

    $ oc -n openshift-security-profiles patch spod spod --type=merge -p '{"spec":{"enableMemoryOptimization":true}}'
  2. To record a security profile for a pod, the pod must be labeled with spo.x-k8s.io/enable-recording: "true":

    apiVersion: v1
    kind: Pod
    metadata:
      name: my-recording-pod
      labels:
        spo.x-k8s.io/enable-recording: "true"
    # ...

7.8.4. Customizing daemon resource requirements

The default resource requirements of the daemon container can be adjusted by using the field daemonResourceRequirements from the spod configuration.

Procedure

  • To specify the memory and cpu requests and limits of the daemon container, run the following command:

    $ oc -n openshift-security-profiles patch spod spod --type merge -p \
        '{"spec":{"daemonResourceRequirements": { \
        "requests": {"memory": "256Mi", "cpu": "250m"}, \
        "limits": {"memory": "512Mi", "cpu": "500m"}}}}'

7.8.5. Setting a custom priority class name for the spod daemon pod

The default priority class name of the spod daemon pod is set to system-node-critical. A custom priority class name can be configured in the spod configuration by setting a value in the priorityClassName field.

Procedure

  • Configure the priority class name by running the following command:

    $ oc -n openshift-security-profiles patch spod spod --type=merge -p '{"spec":{"priorityClassName":"my-priority-class"}}'

    Example output

    securityprofilesoperatordaemon.openshift-security-profiles.x-k8s.io/spod patched

7.8.6. Using metrics

The openshift-security-profiles namespace provides metrics endpoints, which are secured by the kube-rbac-proxy container. All metrics are exposed by the metrics service within the openshift-security-profiles namespace.

The Security Profiles Operator includes a cluster role and corresponding binding spo-metrics-client to retrieve the metrics from within the cluster. There are two metrics paths available:

  • metrics.openshift-security-profiles/metrics: for controller runtime metrics
  • metrics.openshift-security-profiles/metrics-spod: for the Operator daemon metrics

Procedure

  1. To view the status of the metrics service, run the following command:

    $ oc get svc/metrics -n openshift-security-profiles

    Example output

    NAME      TYPE        CLUSTER-IP   EXTERNAL-IP   PORT(S)   AGE
    metrics   ClusterIP   10.0.0.228   <none>        443/TCP   43s

  2. To retrieve the metrics, query the service endpoint using the default ServiceAccount token in the openshift-security-profiles namespace by running the following command:

    $ oc run --rm -i --restart=Never --image=registry.fedoraproject.org/fedora-minimal:latest \
        -n openshift-security-profiles metrics-test -- bash -c \
        'curl -ks -H "Authorization: Bearer $(cat /var/run/secrets/kubernetes.io/serviceaccount/token)" https://metrics.openshift-security-profiles/metrics-spod'

    Example output

    # HELP security_profiles_operator_seccomp_profile_total Counter about seccomp profile operations.
    # TYPE security_profiles_operator_seccomp_profile_total counter
    security_profiles_operator_seccomp_profile_total{operation="delete"} 1
    security_profiles_operator_seccomp_profile_total{operation="update"} 2

  3. To retrieve metrics from a different namespace, link the ServiceAccount to the spo-metrics-client ClusterRoleBinding by running the following command:

    $ oc get clusterrolebinding spo-metrics-client -o wide

    Example output

    NAME                 ROLE                             AGE   USERS   GROUPS   SERVICEACCOUNTS
    spo-metrics-client   ClusterRole/spo-metrics-client   35m                    openshift-security-profiles/default

7.8.6.1. controller-runtime metrics

The controller-runtime metrics and the DaemonSet endpoint metrics-spod provide a set of default metrics. Additional metrics are provided by the daemon, which are always prefixed with security_profiles_operator_.

7.8.7. Use the log enricher

The Security Profiles Operator contains a log enrichment feature, which is disabled by default. The log enricher container runs with privileged permissions in the host PID namespace (hostPID) so it can read audit logs from the local node.

Important

The log enricher must have permissions to read the host processes.

Procedure

  1. Patch the spod configuration to enable the log enricher by running the following command:

    $ oc -n openshift-security-profiles patch spod spod \
        --type=merge -p '{"spec":{"enableLogEnricher":true}}'

    Example output

    securityprofilesoperatordaemon.security-profiles-operator.x-k8s.io/spod patched

    Note

    The Security Profiles Operator will re-deploy the spod daemon set automatically.

  2. View the audit logs by running the following command:

    $ oc -n openshift-security-profiles logs -f ds/spod log-enricher

    Example output

    I0623 12:51:04.257814 1854764 deleg.go:130] setup "msg"="starting component: log-enricher"  "buildDate"="1980-01-01T00:00:00Z" "compiler"="gc" "gitCommit"="unknown" "gitTreeState"="clean" "goVersion"="go1.16.2" "platform"="linux/amd64" "version"="0.4.0-dev"

7.8.7.1. Using the log enricher to trace an application

You can use the Security Profiles Operator log enricher to trace an application.

Procedure

  1. To trace an application, create a SeccompProfile logging profile:

    apiVersion: security-profiles-operator.x-k8s.io/v1beta1
    kind: SeccompProfile
    metadata:
      name: log
    spec:
      defaultAction: SCMP_ACT_LOG
  2. Create a pod object to use the profile:

    apiVersion: v1
    kind: Pod
    metadata:
      name: log-pod
      namespace: default
    spec:
      securityContext:
        runAsNonRoot: true
        seccompProfile:
          type: Localhost
          localhostProfile: operator/log.json
      containers:
      - name: log-container
        image: quay.io/security-profiles-operator/test-nginx-unprivileged:1.21
        securityContext:
          allowPrivilegeEscalation: false
          capabilities:
            drop: [ALL]
  3. Examine the log enricher output by running the following command:

    $ oc -n openshift-security-profiles logs -f ds/spod log-enricher

    Example output

    …

7.8.8. Configure webhooks

Configure webhooks for profile binding and recording so you can limit them to selected namespaces or objects, or allow requests to continue if a webhook fails. Profile binding and recording object configurations are MutatingWebhookConfiguration CRs, managed by the Security Profiles Operator.

To change the webhook configuration, edit the webhookOptions field in the spod custom resource. You can modify the failurePolicy, namespaceSelector, and objectSelector variables to set the webhooks to soft-fail or to restrict them to a subset of namespaces. If a webhook fails, other namespaces or resources are not affected.

Procedure

  1. Set the recording.spo.io webhook configuration to record only pods labeled with spo-record=true by creating the following patch file:

    spec:
      webhookOptions:
        - name: recording.spo.io
          objectSelector:
            matchExpressions:
              - key: spo-record
                operator: In
                values:
                  - "true"
  2. Patch the spod/spod instance by running the following command:

    $ oc -n openshift-security-profiles patch spod \
        spod -p $(cat /tmp/spod-wh.patch) --type=merge
  3. To view the resulting MutatingWebhookConfiguration object, run the following command:

    $ oc get MutatingWebhookConfiguration \
        spo-mutating-webhook-configuration -oyaml

7.9. Advanced Audit Logging Framework

With the Advanced Audit Logging Framework in the OpenShift Container Platform Security Profiles Operator (SPO), you can correlate cluster users with actions during oc exec, oc rsh, and oc debug sessions.

The Advanced Audit Logging Framework in SPO 0.10.0 logs activity from an Red Hat Enterprise Linux CoreOS (RHCOS) container back to the hosting cluster and produces detailed logs in a JSON Lines format.

7.9.1. Benefits of the Advanced Audit Logging Framework

The kubectl exec, oc exec, oc rsh and oc debug commands do not pass user authentication details into the exec session on the container, making it hard to correlate Kubernetes user actions caused by actions on the host. The audit logger in SPO addresses this with mutating webhooks that inject the request UID from the Kubernetes API server as an environment variable into the session. Every request to the API server including the request to start a new exec session has a request UID. This request UID is then logged by the Advanced Audit Logging Framework. The request ID is used to correlate the activity with the API server audit logs, providing an audit trail within the node.

With the addition of the Advanced Audit Logging Framework, SPO now has two use cases:

  • Pod auditing
  • Node auditing

The use of privileged seccompProfile configuration is required only for the case of node auditing.

Note

The Security Profiles Operator supports only Red Hat Enterprise Linux CoreOS (RHCOS) worker nodes appropriate to the version of OpenShift Container Platform in use.

Red Hat Enterprise Linux (RHEL) nodes are not supported.

7.9.2. Performance considerations

It is important to consider the performance cost of using seccomp profiles for extensive logging. SPO is designed to minimize this impact by primarily logging only process creations and handling them asynchronously. This approach helps prevent logging from becoming a bottleneck on your nodes.

The Advanced Audit Logging feature uses eBPF as a supplemental data source. While it is possible for eBPF to be used as a primary data source for this type of logging, that functionality is not currently a configurable feature within the Operator. For most use cases, the default asynchronous, process-creation-focused logging approach provides an excellent balance between security visibility and cluster performance.

7.9.3. Prerequisites for the Advanced Audit Logging Framework

Before enabling the Advanced Audit Logging Framework, ensure the following requirements are met.

Security Profiles Operator version 0.10.0 or later is installed. The Advanced Audit Logging Framework requires Security Profiles Operator version 0.10.0 or later.

For node debugging sessions:

  • To audit oc debug node sessions, CRI-O version 1.33 or later is required. It is available in OpenShift Container Platform 4.20 or later.
  • The --privileged-seccomp-profile flag must be configured in CRI-O to apply seccompProfiles to privileged containers.
  • The supported Linux used with the Advanced Audit Logging Framework is Red Hat Enterprise Linux CoreOS (RHCOS) running in a container in OpenShift Container Platform 4.20 or later.

If you are using the CRI-O runtime, you must configure it to allow seccompProfile to be applied to privileged containers. Add the following flag to your CRI-O runtime configuration: --privileged-seccomp-profile=/var/lib/kubelet/seccomp/operator/profile1.json. This is explained in more detail in the Advanced Audit Logging installation and enablement steps. The --privileged-seccomp-profile flag is available starting with OpenShift Container Platform 4.20 and later.

If you are using any version of SPO before 0.9.0, you must perform a migration procedure to install versions 0.9.0 or 0.10.0. The migration procedure converts SPO to operate on cluster-scoped resources.

First-time installation of SPO version 0.10.0 does not require migration. Also, if you are currently on SPO 0.9.0, you do not require migration and can directly upgrade to SPO 0.10.0.

Important

Do not attempt to upgrade directly from SPO versions before 0.9.0 to either 0.9.0 or 0.10.0 if you are currently running SPO. You must perform the migration procedure to convert SPO for operation at the cluster level.

This change allows Advanced Audit Logging of events inside the worker node.

This capability is not provided for control nodes since SPO does not operate on etcd nodes.

7.9.4. The Audit JSON log enricher

The SPO Advanced Audit Logging Framework is enabled by the Audit JSON log enricher. Similar to the log enricher feature, the Audit JSON log enricher watches the auditd (/var/log/audit/audit.log) or the syslog (/var/log/syslog) daemons and generates a new audit log in JSON lines format.

Each JSON line includes the following:

  • Timestamp: When the activity happened, shown in a standard ISO format
  • Executable Name: The name of the program that was run (bash, ls).
  • Linux Command Line Arguments (cmdline): The extra instructions given when the program was started (ls -l /home).
  • User and Group IDs (UID/GID): The identification numbers of the system user who ran the program.
  • System Calls (syscalls): A list of system calls (syscalls) that the process made

This log format and configuration is similar to how Kubernetes records audit logs. This is useful for:

  • Seeing what users and automated processes are doing inside a pod.
  • Tracking when someone uses commands such as kubectl exec to enter a running container and run commands or scripts.
  • Monitoring activities in debug containers where users might run various tools.

7.9.5. Kubernetes API log compared to Advanced Audit Logging output

To understand the value of Advanced Audit Logging, compare the Kubernetes API Server Audit Log to the Advanced Audit Logging output:

Kubernetes API Server Audit Log

{
  "kind": "Event",
  "apiVersion": "audit.k8s.io/v1",
  "level": "Metadata",
  "auditID": "4d434cd4-xxxx-xxxx-xxxx-2d9aa46292ce",

  "objectRef": {
    "resource": "pods",
    "namespace": "test-namespace",
    "name": "test-pod",
    "subresource": "exec"
  },
  "responseStatus": {

    "execmetadata.spo.io/SPO_EXEC_REQUEST_UID": "aec3e0e1-xxxx-xxxx-xxxx-a7c58241f1a9"
  }
}

The correlation key is the SPO_EXEC_REQUEST_UID on the last line in the above file.

  "version": "spo/v1_alpha"
}

7.9.6. Enabling Advanced Audit Logging

To enable Advanced Audit Logging, configure the Audit JSON log enricher and specify a set of filters to only log user activity.

Procedure

  1. Enable the JSON enricher by running the following command:

    # kubectl -n openshift-security-profiles patch spod spod --type=merge -p '{"spec":{"enableJsonEnricher":true}}'

    Monitor the SPOD pods for correct restart and wait for all SPOD pods to show Running before proceeding.

  2. Check the pods for application of the change with the following command:

    $ oc get pods -n openshift-security-profiles -l name=spod -w

    Wait until all SPOD pods show Running before proceeding.

    Note

    Each configuration change triggers a restart of the SPOD pods. After applying a patch, wait for all SPOD pods to return to the Running state before continuing.

    The Audit JSON log enricher uses eBPF as a supplemental data source. While processing auditd logs from /var/log/audit/audit.log, the enricher attempts to fetch ephemeral data from /proc/<pid> directories. Due to a race condition, these files might be deleted before they can be read. To ensure data completeness, the enricher falls back to fetching the necessary information from eBPF whenever it is not found in /proc/<pid>.

7.9.7. Audit JSON Log Enricher configuration

Configure the Audit JSON Log Enricher to set the audit log interval, destination, and file path so Advanced Audit Logging records are written on a schedule and to a location you can collect and review.

Note

Each configuration change triggers a restart of the SPOD pods. After applying a patch, wait for all SPOD pods to return to the Running state before continuing.

Setting the audit log interval determines how often audit logs are created using the auditLogIntervalSeconds option.

Procedure

  1. Configure the audit log interval to 30 seconds by using the following command:

    # kubectl -n openshift-security-profiles patch spod spod --type=merge -p '{"spec":{"enableJsonEnricher":true,"verbosity":0,"jsonEnricherOptions":{"auditLogIntervalSeconds":30}}}'

    Wait until all SPOD pods show Running before proceeding. By default, audit logs go to your standard output in JSON lines format. You can send them to a file instead.

    Configure the Security Profiles Operator to store the log file on the node. Update the security-profiles-operator-profile configmap with two keys. This example YAML uses both keys to set up a host path volume at /tmp/logs.

  2. Create a file such as patch-volume-source.json that contains the following content:

    {
      "data": {
        "json-enricher-log-volume-mount-path": "/tmp/logs",
        "json-enricher-log-volume-source.json": "{\"hostPath\": {\"path\": \"/tmp/logs\",\"type\": \"DirectoryOrCreate\"}}"
      }
    }
    • json-enricher-log-volume-source.json: Defines the type of volume (for example, a host path and empty directory) where logs are stored. This value must be a JSON string that represents a corev1.VolumeSource object.
    • json-enricher-log-volume-mount-path: Specifies the directory path where the log file is generated.
  3. Verify the file contents by running the following command:

    $ cat patch-volume-source.json
  4. Update the security-profiles-operator-profile configmap by using the following command:

    # kubectl patch configmap security-profiles-operator-profile -n openshift-security-profiles --patch-file patch-volume-source.json

    Wait until all SPOD pods show Running before proceeding.

  5. Set the audit log file path by configuring the JSON log enricher with the full path to your audit log file, including the file name, by running the following command:

    # kubectl -n openshift-security-profiles patch spod spod --type=merge -p '{"spec":{"enableJsonEnricher":true,"verbosity":0,"jsonEnricherOptions":{"auditLogPath":"/tmp/logs/audit1.log"}}}'

    Wait until all SPOD pods show Running before proceeding.

7.9.8. Audit log file fine-tuning and rotation

For audit logging to a file, you can manage file size and how long each file is kept. These options are similar to Kubernetes API server log settings.

Procedure

  1. You configure these by patching the JSON log enricher options:

    # kubectl -n openshift-security-profiles patch spod spod --type=merge -p '{"spec":{"enableJsonEnricher":true,"verbosity":0,"jsonEnricherOptions":{"auditLogPath":"/tmp/logs/audit1.log","auditLogMaxSize":500,"auditLogMaxBackups":2,"auditLogMaxAge":10}}}'

    Wait until all SPOD pods show Running before proceeding.

    • auditLogMaxSize: The maximum size (in megabytes) a log file can reach before it’s rotated (a new file is started).
    • auditLogMaxBackups: The maximum number of older, rotated log files to keep. Set to 0 for no limit.
    • auditLogMaxAge: The maximum number of days to keep old log files.
  2. Increase the logging level for the JSON log enricher container to help with debugging. A value of 0 sets minimal logs. A value of 1 sets more detailed logs. You can choose either of these two levels and enable either level with the following command:

    # kubectl -n openshift-security-profiles patch spod spod --type=merge -p '{"spec":{"enableJsonEnricher":true, "verbosity": 1}}'

    Wait until all SPOD pods show Running before proceeding.

7.9.9. Advanced audit logs for a specific pod

To log activity for a single pod, create a SeccompProfile that logs specific syscalls such as execve, and create a ProfileBinding that applies the profile to pods in a target namespace. The SeccompProfile applies cluster-wide. The ProfileBinding applies to workloads in that namespace.

Starting with OpenShift Container Platform 4.20 and CRI-O 1.33, you can apply a SeccompProfile to privileged containers. Add the --privileged-seccomp-profile flag to the CRI-O runtime configuration so that privileged debugging pods are also covered by the profile.

Bind the profile to a namespace to apply it to workloads. New pods in that namespace then receive the profile automatically.

Procedure

  1. Create a file such as profile1.yaml with the following content:

    apiVersion: security-profiles-operator.x-k8s.io/v1beta1
    kind: SeccompProfile
    metadata:
      name: profile1
      namespace: openshift-security-profiles
    spec:
      defaultAction: SCMP_ACT_ALLOW
      syscalls:
      - action: SCMP_ACT_LOG
        names:
          - execve
          - clone
          - getpid

    This profile allows all normal actions (defaultAction: SCMP_ACT_ALLOW). It specifically tells the system to log when a process tries to run a new program (execve), create a new process (clone), or get its own process ID (getpid). These actions often indicate user interaction within a pod.

  2. Apply this SeccompProfile to your cluster by running the following command:

    # kubectl apply -f profile1.yaml
    Note

    The Security Profiles Operator must use the privileged SeccompProfile.

  3. Create a file named image_sec_comp.yaml that contains the following YAML:

    apiVersion: security-profiles-operator.x-k8s.io/v1alpha1
    kind: ProfileBinding
    metadata:
      namespace: default
      name: all-pod-binding
    spec:
      profileRef:
        kind: SeccompProfile
        name: profile1
      image: "*"
  4. Apply the binding by running the following command:

    # kubectl apply -f image_sec_comp.yaml
  5. Label the namespace to activate the binding by running the following command:

    # kubectl label ns default spo.x-k8s.io/enable-binding=true
  6. Create a file such as my-pod.yaml that contains the following pod definition:

    apiVersion: v1
    kind: Pod
    metadata:
      name: my-pod
      labels:
        app: my-app
    spec:
      securityContext:
        seccompProfile:
          type: Localhost
          localhostProfile: operator/profile1.json
      containers:
        - name: nginx
          image: quay.io/security-profiles-operator/test-nginx:1.19.1
    • type: Localhost means you are using a profile that you defined in the cluster.
    • localhostProfile: operator/profile1.json tells the pod to use the profile1 profile that you created. The operator/ path is where the Security Profiles Operator stores these profiles.
  7. Apply the pod definition by running the following command:

    # kubectl apply -f my-pod.yaml
  8. Open a shell in the pod by running the following command:

    # kubectl exec -it my-pod -- /bin/sh
  9. Create an empty file in the pod by running the following command:

    # touch /tmp/audittest/demo-file
  10. Stream the advanced audit log by running the following command:

    # kubectl -n openshift-security-profiles logs --since=1m --selector name=spod -c json-enricher --max-log-requests 6 -f
  11. Identify the node where the pod runs by running the following command:

    # kubectl get pod my-pod -o wide

    The audit log file specified in the auditLogPath field is written to the file system on the node where the pod is running. To inspect the audit logs, access the node and open the file at the configured path, such as /tmp/logs/audit1.log.

  12. Access the node by running the following command:

    $ sudo ssh core@<node_name>
  13. View the audit log by running the following command:

    $ cat /tmp/logs/audit1.log

7.9.10. Monitor the audit logs

Monitor advanced audit logs from the json-enricher container, by streaming pod logs or by reading the audit log file on the node, so you can verify that Advanced Audit Logging is capturing session activity.

The audit log file is specified in the auditLogPath field and is written to the file system on the node where the pod is running. To inspect the audit logs, access the node and open the file at the configured path, such as /tmp/logs/audit1.log.

Procedure

  1. Stream the advanced audit log by using the following command:

    # kubectl -n openshift-security-profiles logs --since=1m --selector name=spod -c json-enricher --max-log-requests 6 -f
  2. Identify the node on which the pod is scheduled by using the following command:

    # kubectl get pod my-pod -o wide
  3. Access the node by using the following command:

    $ sudo ssh core@<node_name>
  4. View the audit log by using the following command:

    $ cat /tmp/logs/audit1.log

    Example output

    {
    "auditID": "a1b2c3d4-e5f6-7890-abcd-111111111111",
    "cmdLine": "mkdir /tmp/audittest ",
    "executable": "/bin/bash",

    "node": {"name": "worker-1"},
    "pid": 27184,
    "requestUID": "f011c4a3-b20e-44ed-bb91-23e03ae31b3e",
    "resource": {
    "container": "nginx",
    "namespace": "default",
    "pod": "my-pod"
    },
    "syscalls": ["getpid", "execve"],
    "timestamp": "2026-02-16T06:34:53.000Z",
    "uid": 0,
    "version": "spo/v1_alpha"
    }
    {
    "auditID": "a1b2c3d4-e5f6-7890-abcd-222222222222",
    "cmdLine": "touch /tmp/audittest/demo-file ",

    "uid": 0,
    "version": "spo/v1_alpha"
    }

7.9.11. Audit node debugging sessions

Enable privileged seccomp profiles in CRI-O so Advanced Audit Logging can record activity from kubectl debug and oc debug node sessions.

If you are using the CRI-O runtime, you must configure it to allow seccomp profiles on privileged containers by adding the --privileged-seccomp-profile=/var/lib/kubelet/seccomp/operator/profile1.json flag to your CRI-O runtime configuration.

Note

The --privileged-seccomp-profile flag is available starting with OpenShift Container Platform 4.20 or later and CRI-O version 1.33 or later.

Procedure

  1. SSH into the target node using the following command:

    # ssh core@<node_ip_address>
  2. Check to see if the files are there:

    # ls /var/lib/kubelet/seccomp/operator/

    Example output

    # kubelet-config.json  profile1.json

  3. Stop the kubelet with the following commands:

    # systemctl stop kubelet
  4. Stop CRI-O with the command:

    # systemctl stop crio
  5. Set the CRI-O options with the following command:

    # echo "CRIO_CONFIG_OPTIONS --privileged-seccomp-profile=/var/lib/kubelet/seccomp/operator/profile1.json" > /etc/sysconfig/crio
  6. Now restart the kubelet with this command:

    # systemctl start kubelet
  7. Restart CRI-O with this command:

    # systemctl start crio
  8. To audit kubectl debug sessions, run the following command:

    # kubectl debug node/<node_name> -it --image=ubuntu -- bash

    Create the file on the container for the debugging information.

  9. chroot to the host with this command:

    # chroot /host
  10. Go into the /tmp directory with this command:

    # cd /tmp
  11. Create an empty file named demonodedebug with this command:

    # touch demonodedebug
  12. Exit the node with the command:

    # exit
  13. To monitor the logs, SSH to a node with this command:

    $ sudo ssh core@<node_name>
  14. View the audit log using this command:

    $ cat /tmp/logs/audit1.log

    Example output

    {
      "auditID": "edce381a-998d-4f3f-99d8-d0c4d0c8a613",
      "cmdLine": "touch demonodedebug",
      "executable": "/usr/bin/bash",
      "gid": 0,
      "node": {"name": "worker-1"},
      "pid": 99086,
      "resource": {
        "container": "container-00",
        "namespace": "openshift-security-profiles",
        "pod": "worker-1-debug"
      },
      "syscalls": ["execve", "getpid"],
      "timestamp": "2026-02-12T13:50:11.000Z",
      "uid": 0,
      "version": "spo/v1_alpha"
    }

7.9.12. Correlate with Kubernetes audit logs

Use the requestUID from the Security Profiles Operator (SPO) log to find the corresponding API server log entry, confirming who initiated the session.

Procedure

  1. Start the pod by running the following command:

    $ oc exec my-pod -c nginx -- sh -c "touch /tmp/testfile.txt"
  2. Identify the node where the pod is running:

    $ NODE=$(oc get pod my-pod -o jsonpath='{.spec.nodeName}')
  3. Access the node and check the JSON enriched audit log using the following commands:

    # oc debug node/$NODE
    # chroot /host
    # grep "testfile" /tmp/logs/audit1.log | jq .

7.9.13. Audit JSON Log Enricher output

For an exec session, the Audit JSON Log Enricher records two entries: the SPO_EXEC_REQUEST_UID injection and the command that ran on the pod. Match the shared UID value to connect the entries.

  1. The first listing is the container runtime wrapper.

    {
      "auditID": "062e2bd2-xxxx-xxxx-xxxx-57fb39d65a99",
      "cmdLine": "env SPO_EXEC_REQUEST_UID=aec3e0e1-xxxx-xxxx-xxxx-a7c58241f1a9 sh -c touch /tmp/testfile.txt ",
      "executable": "/usr/bin/crun",
      "pid": 144966,
      "requestUID": "aec3e0e1-xxxx-xxxx-xxxx-a7c58241f1a9",
      "resource": {
        "container": "nginx",
        "namespace": "default",
        "pod": "my-pod"
      },
      "node": {
        "name": "worker-1"
      },
      "syscalls": ["execve", "getpid", "clone"],
      "timestamp": "2026-02-16T14:01:07.000Z"
    }
  2. The second listing is the actual command executed.

    {
      "auditID": "d586679d-xxxx-xxxx-xxxx-9dc8ab273065",
      "cmdLine": "touch /tmp/testfile.txt ",
      "executable": "/bin/dash",
      "pid": 144968,
      "requestUID": "aec3e0e1-xxxx-xxxx-xxxx-a7c58241f1a9", // Correlation key
      "resource": {
        "container": "nginx",
        "namespace": "default",
        "pod": "my-pod"
      },
      "node": {
        "name": "worker-1"
      },
      "syscalls": ["execve"],
      "timestamp": "2026-02-16T14:01:07.000Z"
    }
  3. You can search the Kubernetes API audit log by using the requestUID with the following command:

    $ oc adm node-logs --role=master --path=kube-apiserver/audit.log | grep request_UID

7.9.14. Kubernetes API audit log output

The Kubernetes API audit log output is YAML. It includes the SPO_EXEC_REQUEST_UID field that provides the correlation key for searching the Advanced Audit Logging output.

{
  "kind": "Event",
  "apiVersion": "audit.k8s.io/v1",
  "level": "Metadata",
  "auditID": "4d434cd4-xxxx-xxxx-xxxx-2d9aa46292ce",
  "stage": "ResponseComplete",
  "requestURI": "/api/v1/namespaces/test-namespace/pods/test-pod/exec?command=sh&command=-c&command=touch+/tmp/testfile.txt&container=nginx",
  "verb": "create",
  "user": {
    "username": "kube:admin",
    "groups": ["system:cluster-admins", "system:authenticated"]
  },
  "sourceIPs": ["xxx.xxx.xxx.xxx"],
  "userAgent": "oc/4.19.0 (linux/amd64)",
  "objectRef": {
    "resource": "pods",
    "namespace": "default",
    "name": "my-pod",
    "subresource": "exec"
  },
  "responseStatus": {
    "code": 101
  },
  "requestReceivedTimestamp": "2026-02-16T14:01:06.056518Z",
  "annotations": {
    "authorization.k8s.io/decision": "allow",
    "authorization.k8s.io/reason": "RBAC: allowed by ClusterRoleBinding...",
    "execmetadata.spo.io/SPO_EXEC_REQUEST_UID": "aec3e0e1-xxxx-xxxx-xxxx-a7c58241f1a9"
}

The final field in this example, SPO_EXEC_REQUEST_UID is the correlation key.

7.9.15. Correlation key

You can build a complete audit trail by matching correlation keys across logs. The requestUID field in Audit JSON Enricher logs matches the annotations.execmetadata.spo.io/SPO_EXEC_REQUEST_UID annotation in the Kubernetes API audit log.

For example, the API audit log can show that kube:admin ran a command, and the SPO JSON Enricher log can show the system-level action, such as touch /tmp/testfile.txt.

aec3e0e1-xxxx-xxxx-xxxx-a7c58241f1a9

7.9.16. Correlating with API Server Audit Log

By default, when you use the kubectl exec command to access a pod or container, Kubernetes does not pass the user’s authentication details into that session’s environment. This means the Audit JSON log enricher cannot provide audit information for exec commands. The UID or GID shown, maps to the system user. In most cases this would be the root user.

To address this, the Audit JSON log enricher relies on mutating webhooks (execmetadata.spo.io and nodedebuggingpod.spo.io). The webhook injects the exec requestUID as an environment variable into the exec session. When the administrator enables audit logging on the API server, the webhooks add the SPO_EXEC_REQUEST_UID audit annotation. The API server audit log contains this information. This request ID is also available in the JSON lines produced by the Audit JSON log enricher, specifically within the requestUID field.

By default, these webhooks are enabled for all namespaces with the Audit JSON log enricher enabled. To reduce the scope of this webhook you can disable it for certain namespaces.

Procedure

  1. Edit the spod security profile by running the following command:

    $ oc edit spod spod -n openshift-security-profiles
  2. Add webhookOptions to the spec. Locate the spec section and add the following webhookOptions block to instruct the webhook to apply to a specific namespace.

    spec:
      webhookOptions:
        - name: execmetadata.spo.io # or nodedebuggingpod.spo.io
          namespaceSelector:
          #...add rules

    After saving your changes, the Operator reconfigures the mutating webhook, allowing request details to be passed into oc exec sessions cluster-wide.

7.9.17. Use the mutating webhook

Use the mutating webhook so Advanced Audit Logging can correlate cluster users with actions in oc exec, oc rsh, and oc debug sessions.

The mutating webhook injects the SPO_EXEC_REQUEST_UID environment variable into your exec request. If a container already defines a variable with that name, the injected value overrides it for the exec session.

When you use kubectl debug node/<node_name>, the nodedebuggingpod.spo.io webhook injects SPO_EXEC_REQUEST_UID into the debug pod.

7.9.17.1. The debug pod

This webhook primarily identifies kubectl debug pods by the label app.kubernetes.io/managed-by: kubectl-debug, which is added by the kubectl client. Because this label might vary across different Kubernetes client implementations, such as how oc debug in OpenShift Container Platform uses debug.openshift.io/managed-by: oc-debug, you might need to configure additional webhookOptions to ensure the webhook catches all relevant debug pods.

For example, to add oc debug pods, use the following yaml:

# ... (rest of your spod configuration)
spec:
  webhookOptions:
    - name: nodedebuggingpodmetada.spo.io
      objectSelector:
        matchLabels: # Use matchLabels for exact matching
          debug.openshift.io/managed-by: "oc-debug"
# ... (other webhook rule details such as rules, clientConfig, etc.)

7.9.18. Disabling Advanced Audit Logging

You can disable advanced audit logging and revert all configurations by deleting the test pod, the seccompProfile, the JSON Log Enricher and resetting all spod pod options.

Procedure

  1. Delete the test pod with the following command:

    oc delete pod my-pod
  2. Delete the seccompProfile using this command:

    oc delete seccompprofile profile1 -n openshift-security-profiles
  3. Disable the JSON Log Enricher and reset all options:

    oc patch spod spod -n openshift-security-profiles --type merge -p '{ "spec": { "enableJsonEnricher": false, "jsonEnricherOptions": { "auditLogPath": "", "auditLogMaxSize": 0, "auditLogMaxBackups": 0, "auditLogMaxAge": 0, "auditLogIntervalSeconds": 0 } }}'
  4. Wait for spod pods to restart. Run the following command to check:

    oc get pods -n openshift-security-profiles -l name=spod -w

    Wait until all spod pods show Running.

  5. Revert the ConfigMap volume patch with the following command:

    oc patch configmap security-profiles-operator-profile -n openshift-security-profiles --type merge -p '{"data":{"patch-volume-source.json":""}}'
  6. Verify that the configuration has been successfully updated:

    oc get spod spod -n openshift-security-profiles -o jsonpath='{.spec.enableJsonEnricher}'

    Expected output:

    false

7.10. Troubleshooting the Security Profiles Operator

Troubleshoot the Security Profiles Operator to diagnose a problem or provide information in a bug report.

7.10.1. Inspecting seccomp profiles

Corrupted seccomp profiles can disrupt your workloads. Ensure that the user cannot abuse the system by not allowing other workloads to map any part of the path /var/lib/kubelet/seccomp/operator.

Procedure

  1. Confirm that the profile is reconciled by running the following command:

    $ oc -n openshift-security-profiles logs openshift-security-profiles-<id>

    Example output

    I1019 19:34:14.942464       1 main.go:90] setup "msg"="starting openshift-security-profiles"  "buildDate"="2020-10-19T19:31:24Z" "compiler"="gc" "gitCommit"="a3ef0e1ea6405092268c18f240b62015c247dd9d" "gitTreeState"="dirty" "goVersion"="go1.15.1" "platform"="linux/amd64" "version"="0.2.0-dev"

  2. Confirm that the seccomp profiles are saved into the correct path by running the following command:

    $ oc exec -t -n openshift-security-profiles openshift-security-profiles-<id> \
        -- ls /var/lib/kubelet/seccomp/operator/my-namespace/my-workload

    Example output

    profile-block.json
    profile-complain.json
