After Red Hat Advanced Cluster Management is installed, observability certificates are created and used by the observability components, to provide mutual TLS on the traffic between the hub cluster and managed cluster. The Kubernetes secrets that are associated with the observability certificates.

The open-cluster-management-observability namespace contain the following certificates:

The open-cluster-management-addon-observability namespace contain the following certificates on managed clusters:

The CA certificates are valid for five years and other certificates are valid for one year. All observability certificates are automatically refreshed upon expiration.

View the following list to understand the effects when certificates are automatically renewed:

If you do not want to use the default observability CA certificates generated by Red Hat Advanced Cluster Management, you can choose to use the BYO observability CA certificates before you enable observability.

You can view a list of hub cluster managed certificates that use OpenShift Service Serving Certificates service internally. Run the following command to list the certificates:

for ns in multicluster-engine open-cluster-management ; do echo "$ns:" ; oc get secret -n $ns -o custom-columns=Name:.metadata.name,Expiration:.metadata.annotations.service\\.beta\\.openshift\\.io/expiry | grep -v '<none>' ; echo ""; done

Note: If observability is enabled, there are additional namespaces where certificates are created.

You can refresh a hub cluster managed certificate by running the delete secret command in the List hub cluster managed certificates section. When you identify the certificate that you need to refresh, delete the secret that is associated with the certificate. For example, you can delete a secret by running the following command:

oc delete secret grc-0c925-grc-secrets -n open-cluster-management

Note: After you delete the secret, a new one is created. However, you must restart pods that use the secret manually so they can begin to use the new certificate.

You can refresh OpenShift Container Platform managed certificates, which are certificates that are used by Red Hat Advanced Cluster Management webhooks.

Complete the following steps to refresh Red Hat Advanced Cluster Management webhook certificate:

View the following table for a summarized list of the pods that contain certificates and whether a secret needs to be deleted prior to restarting the pod:

CA certificates can be associated with Git channel that are a part of the Red Hat Advanced Cluster Management application management. See Using custom CA certificates for a secure HTTPS connection for more details.

Helm channels allow you to disable certificate validation. Helm channels where certificate validation is disabled, must be configured in development environments. Disabling certificate validation introduces security risks.

Certificates are used to authenticate managed clusters with the hub. Therefore, it is important to be aware of troubleshooting scenarios associated with these certificates. View Troubleshooting imported clusters offline after certificate change for more details.

The managed cluster certificates are refreshed automatically.

Complete the following steps to rotate the gatekeeper webhook certificate:

The gatekeeper webhook certificate is rotated.

Use the certificate policy controller to create and manage certificate policies on managed clusters. See Policy controllers to learn more about controllers. Return to the Risk and compliance page for more information.

The policy_governance_info is collected by OpenShift Container Platform monitoring, and some aggregate data is collected by Red Hat Advanced Cluster Management observability, if it is enabled.

Note: If observability is enabled, you can enter a query for the metric from the Grafana Explore page.

When you create a policy, you are creating a root policy. The framework watches for root policies as well as PlacementRules and PlacementBindings, to determine where to create propagated policies in order to distribute the policy to managed clusters. For both root and propagated policies, a metric of 0 is recorded if the policy is compliant, and 1 if it is non-compliant.

The policy_governance_info metric uses the following labels:

These labels and values enable queries that can show us many things happening in the cluster that might be difficult to track.

Note: If the metrics are not needed, and there are any concerns about performance or security, this feature can be disabled. Set the DISABLE_REPORT_METRICS environment variable to true in the propagator deployment. You can also add policy_governance_info metric to the observability allowlist as a custom metric. See Adding custom metrics for more details.

The config_policies_evaluation_duration_seconds histogram tracks the number of seconds it takes to process all configuration policies that are ready to be evaluated on the cluster. Use the following metrics to query the histogram:

Use the config_policies_evaluation_duration_seconds metric to determine if the ConfigurationPolicy evaluationInterval setting needs to be changed for resource intensive policies that do not need frequent evaluation. You can also increase the concurrency at the cost of higher resource utilization on the Kubernetes API server. See Configure the concurrency section for more details.

To receive information about the time used to evaluate configuration policies, perform a Prometheus query that resembles the following expression:

rate(config_policies_evaluation_duration_seconds_sum[10m])/rate (config_policies_evaluation_duration_seconds_count[10m]

The config-policy-controller pod running on managed clusters in the open-cluster-management-agent-addon namespace calculates the metric. The config-policy-controller does not send the metric to observability by default.

You can install the Compliance Operator on your managed cluster by using the Compliance Operator policy. The Compliance Operator policy is created as a Kubernetes configuration policy in Red Hat Advanced Cluster Management. OpenShift Container Platform supports the Compliance Operator policy.

Note: The Compliance operator policy relies on the OpenShift Container Platform Compliance Operator, which is not supported on the IBM Power or IBM Z architectures. See Understanding the Compliance Operator in the OpenShift Container Platform documentation for more information about the Compliance Operator.

When you create a Compliance Operator policy, the following resources are created:

When you create an E8 scan policy the following resources are created:

Note: Automatic remediation is supported. Set the remediation action to enforce to create ScanSettingBinding resource.

See a sample of the policy-compliance-operator-e8-scan.yaml. See Managing security policies for more information. Note: After your E8 policy is deleted, it is removed from your target cluster or clusters.

When you create an OpenShift CIS scan policy the following resources are created:

See a sample of the policy-compliance-operator-cis-scan.yaml file. For more information on creating policies, see Managing security policies.

For more information about installing and configuring Red Hat Ansible Automation Platform, see Setting up Ansible tasks.

After you log into your Red Hat Advanced Cluster Management hub cluster, select Governance from the navigation menu, and then click on the Policies tab to view the policy tables.

Configure an automation for a specific policy by clicking Configure in the Automation column. You can create automation when the policy automation panel appears. From the Ansible credential section, click the drop-down menu to select an Ansible credential. If you need to add a credential, see Managing credentials overview.

Note: This credential is copied to the same namespace as the policy. The credential is used by the AnsibleJob resource that is created to initiate the automation. Changes to the Ansible credential in the Credentials section of the console is automatically updated.

After a credential is selected, click the Ansible job drop-down list to select a job template. In the Extra variables section, add the parameter values from the extra_vars section of the PolicyAutomation. Select the frequency of the automation. You can select Run once mode, Run everyEvent mode, or Disable automation.

Save your policy violation automation by selecting Submit. When you select the View Job link from the Ansible job details side panel, the link directs you to the job template on the Search page. After you successfully create the automation, it is displayed in the Automation column.

Note: When you delete a policy that has an associated policy automation, the policy automation is automatically deleted as part of clean up.

Your policy violation automation is created from the console.

Complete the following steps to configure a policy violation automation from the CLI:

Customize your local repository by consolidating the stable and community policies into a single folder. Remove the policies you do not want to use. Complete the following steps to customize your local repository:

After you are satisfied with the changes you have made to your directory, commit and push your changes to Git so that they can be accessed by your cluster.

Note: This example is used to show the basics of how to use policies with GitOps, so you might have a different workflow to get changes to your branch.

Complete the following steps:

Your changes are committed.

After you push your changes, you can deploy the policies to your Red Hat Advanced Cluster Management for Kubernetes installation. Post deployment, your hub cluster is connected to your Git repository. Any further changes to your chosen branch of the Git repository is reflected in your cluster.

Note: By default, policies deployed with GitOps use the merge reconcile option. If you want to use the replace reconcile option instead, add the apps.open-cluster-management.io/reconcile-option: replace annotation to the Subscription resource. See Application Lifecycle for more details.

The deploy.sh script creates Channel and Subscription resources in your hub cluster. The channel connects to the Git repository, and the subscription specifies the data to bring to the cluster through the channel. As a result, all policies defined in the specified subdirectory are created on your hub. After the policies are created by the subscription, Red Hat Advanced Cluster Management analyzes the policies and creates additional policy resources in the namespace associated with each managed cluster that the policy is applied to, based on the defined placement rule.

The policy is then copied to the managed cluster from its respective managed cluster namespace on the hub cluster. As a result, the policies in your Git repository are pushed to all managed clusters that have labels that match the clusterSelector that are defined in the placement rule of your policy.

Complete the following steps:

After you run the deploy.sh script, any user with access to the repository can commit changes to the branch, which pushes changes to existing policies on your clusters.

Note: To deploy policies with subscriptions, complete the following steps:

Verify that your changes were applied to your policies from the console. You can also make more changes to your policy from the console, however the changes are reverted when the Subscription is reconciled with the Git repository. Complete the following steps:

Template functions, such as resource-specific and generic lookup template functions, are available for referencing Kubernetes resources on the hub cluster (using the {{hub …​ hub}} delimiters), or managed cluster (using the {{ …​ }} delimiters). See Support for hub cluster templates in configuration policies for more details. The resource-specific functions are used for convenience and makes content of the resources more accessible. If you use the generic function, lookup, which is more advanced, it is best to be familiar with the YAML structure of the resource that is being looked up. In addition to these functions, utility functions like base64enc, base64dec, indent, autoindent, toInt, toBool, and more are also available.

To conform templates with YAML syntax, templates must be set in the policy resource as strings using quotes or a block character (| or >). This causes the resolved template value to also be a string. To override this, consider using toInt or toBool as the final function in the template to initiate further processing that forces the value to be interpreted as an integer or boolean respectively.

In addition to managed cluster templates that are dynamically customized to the target cluster, Red Hat Advanced Cluster Management also supports hub cluster templates to define configuration policies using values from the hub cluster. This combination reduces the need to create separate policies for each target cluster or hardcode configuration values in the policy definitions.

Hub cluster templates are based on Golang text template specifications, and the {{hub … hub}} delimiter indicates a hub cluster template in a configuration policy.

For security, both resource-specific and the generic lookup functions in hub cluster templates are restricted to the namespace of the policy on the hub cluster. View the Comparison of hub and managed cluster templates for additional details.

Important: If you use hub cluster templates to propagate secrets or other sensitive data, the sensitive data exists in the managed cluster namespace on the hub cluster and on the managed clusters where that policy is distributed. The template content is expanded in the policy, and policies are not encrypted by the OpenShift Container Platform ETCD encryption support. To address this, use fromSecret, which automatically encrypts the values from the Secret, or protect to encrypt other values.

Set object templates with a YAML string representation. The object-template-raw parameter is an optional parameter that supports advanced templating use-cases, such as if-else and the range function. The following example is defined to add the species-category: mammal label to any ConfigMap in the default namespace that has a name key equal to Sea Otter:

object-templates-raw: |
  {{- range (lookup "v1" "ConfigMap" "default" "").items }}
  {{- if eq .data.name "Sea Otter" }}
  - complianceType: musthave
    objectDefinition:
      kind: ConfigMap
      apiVersion: v1
      metadata:
        name: {{ .metadata.name }}
        namespace: {{ .metadata.namespace }}
        labels:
          species-category: mammal
  {{- end }}
  {{- end }}

Note: While spec.object-templates and spec.object-templates-raw are optional, one of the two parameter fields must be set.

You can create a security policy from the command line interface (CLI) or from the console.

Required access: Cluster administrator

Important: You must define a placement rule and placement binding to apply your policy to a specific cluster. Enter a valid value for the Cluster selector field to define a PlacementRule and PlacementBinding. See Resources that support support set-based requirements in the Kubernetes documentation for a valid expression.

Learn to update security policies by viewing the following section.

Delete a security policy from the CLI or the console.

Use the pruneObjectBehavior parameter in a configuration policy to clean up resources that are created by the policy. When pruneObjectBehavior is set, the related objects are only cleaned up after the configuration policy (or parent policy) associated with them is deleted. View the following descriptions of the values that can be used for the parameter:

You can set the value directly in the YAML as you create a policy from the CLI. From the console, you can select the value in the Prune Object Behavior section of the Policy templates step.

Notes:

You can create a YAML file for your configuration policy from the command line interface (CLI) or from the console.

If you have an existing Kubernetes manifest, consider using the Policy Generator to automatically include the manifests in a policy. See the Policy Generator documentation. View the following sections to create a configuration policy:

Learn to update configuration policies by viewing the following section.

Delete a configuration policy from the CLI or the console.

See configuration policy samples that are supported by Red Hat Advanced Cluster Management from the CM-Configuration-Management folder.

Alternatively, you can refer to the Table of sample configuration policies to view other configuration policies that are monitored by the controller. For details to manage other policies, refer to Managing security policies.

Use the governance framework to install the gatekeeper operator. Gatekeeper operator is available in the OpenShift Container Platform catalog. See Adding Operators to a cluster in the OpenShift Container Platform documentation for more information.

Use the configuration policy controller to install the gatekeeper operator policy. During the install, the operator group and subscription pull the gatekeeper operator to install it in your managed cluster. Then, the gatekeeper operator creates a gatekeeper CR to configure gatekeeper. View the Gatekeeper operator CR sample.

Gatekeeper operator policy is monitored by the Red Hat Advanced Cluster Management configuration policy controller, where enforce remediation action is supported. Gatekeeper operator policies are created automatically by the controller when set to enforce.

Install the gatekeeper policy by creating a gatekeeper policy from the console. Alternatively, you can view a sample YAML to deploy policy-gatekeeper-operator.yaml.

After you log into your cluster, navigate to the Governance page.

Select Create policy. As you complete the form, select Gatekeeper Operator from the Specifications field. The parameter values for your policy are automatically populated and the policy is set to inform by default. Set your remediation action to enforce to install gatekeeper.

Note: Default values are generated by the operator. See Gatekeeper Helm Chart for an explanation of the optional parameters that can be used for the gatekeeper operator policy.

The Policy Generator and its integration with the Red Hat Advanced Cluster Management application lifecycle subscription GitOps workflow simplifies the distribution of Kubernetes resource objects to managed OpenShift Container Platform clusters, and Kubernetes clusters through Red Hat Advanced Cluster Management policies. In particular, use the Policy Generator to complete the following actions:

The Policy Generator is a Kustomize generator plug-in that is configured with a manifest of the PolicyGenerator kind and policy.open-cluster-management.io/v1 API version.

To use the plug-in, start by adding a generators section in a kustomization.yaml file. View the following example:

generators:
  - policy-generator-config.yaml

The policy-generator-config.yaml file referenced in the previous example is a YAML file with the instructions of the policies to generate. A simple PolicyGenerator configuration file might resemble the following example:

apiVersion: policy.open-cluster-management.io/v1
kind: PolicyGenerator
metadata:
  name: config-data-policies
policyDefaults:
  namespace: policies
  policySets: []
policies:
  - name: config-data
    manifests:
      - path: configmap.yaml

The configmap.yaml represents a Kubernetes manifest YAML file to be included in the policy. Alternatively, you can set the path to a Kustomize directory, or a directory with multiple Kubernetes manifest YAML files. View the following example:

apiVersion: v1
kind: ConfigMap
metadata:
  name: my-config
  namespace: default
data:
  key1: value1
  key2: value2

The generated Policy, along with the generated PlacementRule and PlacementBinding might resemble the following example:

apiVersion: apps.open-cluster-management.io/v1
kind: PlacementRule
metadata:
  name: placement-config-data
  namespace: policies
spec:

        severity: low

Note that all the fields in the policyDefaults section except for namespace can be overridden for each policy.

You can generate a policy that installs OpenShift GitOps by using the Policy Generator. The OpenShift GitOps operator offers the all namespaces installation mode, which is used in the following example. Create a Subscription manifest file called openshift-gitops-subscription.yaml, similar to the following example:

apiVersion: operators.coreos.com/v1alpha1
kind: Subscription
metadata:
  name: openshift-gitops-operator
  namespace: openshift-operators
spec:
  channel: stable
  name: openshift-gitops-operator
  source: redhat-operators
  sourceNamespace: openshift-marketplace

To pin to a specific version of the operator, add the following parameter and value: spec.startingCSV: openshift-gitops-operator.v<version>. Replace <version> with your preferred version.

A PolicyGenerator configuration file is required. Use the configuration file named policy-generator-config.yaml to generate a policy to install OpenShift GitOps on all OpenShift Container Platform managed clusters. See the following example:

apiVersion: policy.open-cluster-management.io/v1
kind: PolicyGenerator
metadata:
  name: install-openshift-gitops
policyDefaults:
  namespace: policies
  placement:
    clusterSelectors:
      vendor: "OpenShift"
  remediationAction: enforce
policies:
  - name: install-openshift-gitops
    manifests:
      - path: openshift-gitops-subscription.yaml

The last required file is kustomization.yaml, which requires the following configuration:

Generated policies from manifests in the OpenShift Container Platform documentation is supported. Any configuration guidance from the OpenShift Container Platform documentation can be applied using the Policy Generator.

For an operator that uses the namespaced installation mode, such as the Compliance Operator, an OperatorGroup manifest is also required.

Create a YAML file with a Namespace, a Subscription, and an OperatorGroup manifest called compliance-operator.yaml. The following example installs these manifests in the compliance-operator namespace:

apiVersion: v1
kind: Namespace
metadata:
  name: openshift-compliance
---
apiVersion: operators.coreos.com/v1
kind: OperatorGroup
metadata:
  name: compliance-operator
  namespace: openshift-compliance
spec:
  targetNamespaces:
    - compliance-operator
---
apiVersion: operators.coreos.com/v1alpha1
kind: Subscription
metadata:
  name: compliance-operator
  namespace: openshift-compliance
spec:
  channel: release-0.1
  name: compliance-operator
  source: redhat-operators
  sourceNamespace: openshift-marketplace

A PolicyGenerator configuration file is required. View the following PolicyGenerator policy example that installs the Compliance Operator on all OpenShift Container Platform managed clusters:

apiVersion: policy.open-cluster-management.io/v1
kind: PolicyGenerator
metadata:
  name: install-compliance-operator
policyDefaults:
  namespace: policies
  placement:
    clusterSelectors:
      vendor: "OpenShift"
  remediationAction: enforce
policies:
  - name: install-compliance-operator
    manifests:
      - path: compliance-operator.yaml

The last required file is kustomization.yaml, which requires the following configuration:

generators:
  - policy-generator-config.yaml

As a result, the generated policy resembles the following file:

apiVersion: apps.open-cluster-management.io/v1
kind: PlacementRule
metadata:
  name: placement-install-compliance-operator
  namespace: policies
spec:
  clusterConditions:
    - status: "True"

When you install an operator with an OperatorGroup manifest, the OperatorGroup must exist on the cluster before the Subscription is created. Use the policy dependency feature along with the Policy Generator to ensure that the OperatorGroup policy is compliant prior to enforcing the Subscription policy.

Set up policy dependencies by listing the manifests in the order that you want. For example, you might want to create the namespace policy first, create the OperatorGroup next, and create the Subscription last.

Enable the policyDefaults.orderManifests parameter and disable policyDefaults.consolidateManifests in the Policy Generator configuration manifest to automatically set up dependencies between the manifests.

OpenShift GitOps, based on ArgoCD, can also be used to generate policies by using the Policy Generator through GitOps. Since the Policy Generator does not come preinstalled in the OpenShift GitOps container image, some customization must take place. In order to follow along, you must have the OpenShift GitOps Operator installed on the Red Hat Advanced Cluster Management hub cluster and be sure to log into the hub cluster.

In order for OpenShift GitOps to have access to the Policy Generator when you run Kustomize, an Init Container is required to copy the Policy Generator binary from the Red Hat Advanced Cluster Management Application Subscription container image to the OpenShift GitOps container. Additionally, OpenShift GitOps must be configured to provide the --enable-alpha-plugins flag when it runs Kustomize. Start editing the OpenShift GitOps argocd object with the following command:

oc -n openshift-gitops edit argocd openshift-gitops

Then modify the OpenShift GitOps argocd object to contain the following additional YAML content. When a new major version of Red Hat Advanced Cluster Management is released and you want to update the Policy Generator to a newer version, you need to update the registry.redhat.io/rhacm2/multicluster-operators-subscription-rhel8 image used by the Init Container to a newer tag. View the following example and replace <version> with 2.7 or your desired Red Hat Advanced Cluster Management version:

apiVersion: argoproj.io/v1alpha1
kind: ArgoCD
metadata:
  name: openshift-gitops
  namespace: openshift-gitops
spec:
  kustomizeBuildOptions: --enable-alpha-plugins
  repo:
    env:
    - name: KUSTOMIZE_PLUGIN_HOME
      value: /etc/kustomize/plugin
    initContainers:
    - args:
      - -c
      - cp /etc/kustomize/plugin/policy.open-cluster-management.io/v1/policygenerator/PolicyGenerator
        /policy-generator/PolicyGenerator
      command:
      - /bin/bash
      image: registry.redhat.io/rhacm2/multicluster-operators-subscription-rhel8:v<version>
      name: policy-generator-install
      volumeMounts:
      - mountPath: /policy-generator
        name: policy-generator
    volumeMounts:
    - mountPath: /etc/kustomize/plugin/policy.open-cluster-management.io/v1/policygenerator
      name: policy-generator
    volumes:
    - emptyDir: {}
      name: policy-generator

Now that OpenShift GitOps can use the Policy Generator, OpenShift GitOps must be granted access to create policies on the Red Hat Advanced Cluster Management hub cluster. Create the ClusterRole resource called openshift-gitops-policy-admin, with access to create, read, update, and delete policies and placements. Refer to the ealier ClusterRole example.

Additionally, create a ClusterRoleBinding object to grant the OpenShift GitOps service account access to the openshift-gitops-policy-admin ClusterRole. Your ClusterRoleBinding might resemble the following resource:

kind: ClusterRoleBinding
apiVersion: rbac.authorization.k8s.io/v1
metadata:
  name: openshift-gitops-policy-admin
subjects:
  - kind: ServiceAccount
    name: openshift-gitops-argocd-application-controller
    namespace: openshift-gitops
roleRef:
  apiGroup: rbac.authorization.k8s.io
  kind: ClusterRole
  name: openshift-gitops-policy-admin
