Chapter 2. Manually upgrading using the roxctl CLI

Prerequisites

• If you deploy images from a private image registry, first push the new image into your private registry, and then replace your image registry for the commands in this section.

Procedure

• Run the following commands to upgrade Central:

  $ oc -n stackrox patch deploy/central -p '{"spec":{"template":{"spec":{"containers":[{"name":"central","env":[{"name":"ROX_NAMESPACE","valueFrom":{"fieldRef":{"fieldPath":"metadata.namespace"}}}]}]}}}}'

  If you use Kubernetes, enter kubectl instead of oc.

  $ oc -n stackrox patch deployment/scanner -p '{"spec":{"template":{"spec":{"containers":[{"name":"scanner","securityContext":{"runAsUser":65534}}]}}}}'

  Important

  • If you are upgrading from Red Hat Advanced Cluster Security for Kubernetes 3.65.0, you must run the following additional command to create the stackrox-central-diagnostics role:

    $ oc -n stackrox patch role stackrox-central-diagnostics -p '{"rules":[{"apiGroups":["*"],"resources":["deployments","daemonsets","replicasets","configmaps","services"],"verbs":["get","list"]}]}'

    If you use Kubernetes, enter kubectl instead of oc.

  • If you have not installed Red Hat Advanced Cluster Security for Kubernetes by using Helm or Operator, and you want to enable authentication using the OpenShift OAuth server, you must run the following additional command:

    $ oc -n stackrox set env deploy/central ROX_ENABLE_OPENSHIFT_AUTH=true

    $ oc -n stackrox patch serviceaccount/central -p '
    {

    "serviceaccounts.openshift.io/oauth-redirecturi.main": "sso/providers/openshift/callback",
    "serviceaccounts.openshift.io/oauth-redirectreference.main": "{"kind":"OAuthRedirectReference","apiVersion":"v1","reference":{"kind":"Route","name":"central"}}"
    }
    }
    }'

Prerequisites

• If you deploy images from a private image registry, you must first push the new image into your private registry, then edit the commands in the following section to use the name of your private image registry.

Verification

• Check that the new pods have deployed successfully:

  • If you use OpenShift Container Platform, enter the following command:

    $ oc get pod -n stackrox --watch

  • If you use Kubernetes, enter the following command:

    $ kubectl get pod -n stackrox --watch

Procedure

• Check the Central logs:

  If you are using OpenShift Container Platform, enter the following command:

  $ oc logs -n stackrox deploy/central -c central

  Copy to Clipboard Toggle word wrap

  If you are using Kubernetes, enter the following command:

  $ kubectl logs -n stackrox deploy/central -c central

Procedure

• Red Hat Advanced Cluster Security for Kubernetes 3.64.0 renames the SCCs. If you are upgrading from a version below Red Hat Advanced Cluster Security for Kubernetes 3.64.0, you must delete and reapply the SCCs, otherwise, skip this step:

Prerequisites

• You must be using Red Hat Advanced Cluster Security for Kubernetes 3.0.57.0 or higher.
• Before you can perform a rollback, you must have free disk space available on your persistent storage. Red Hat Advanced Cluster Security for Kubernetes uses disk space to keep a copy of databases during the upgrade. If the disk space is not enough to store a copy and the upgrade fails, you will not be able to roll back to an earlier version.

Procedure

• Run the following command to roll back to a previous version when an upgrade fails (before the Central service starts):

  $ oc -n stackrox rollout undo deploy/central

Prerequisites

• You must be using Red Hat Advanced Cluster Security for Kubernetes 3.0.58.0 or higher.
• Before you can perform a rollback, you must have free disk space available on your persistent storage. Red Hat Advanced Cluster Security for Kubernetes uses disk space to keep a copy of databases during the upgrade. If the disk space is not enough to store a copy and the upgrade fails, you will not be able to roll back to an earlier version.

Procedure

• Run the following commands to perform a forced rollback:

  • To forcefully rollback to the previously installed version:

    $ oc -n stackrox rollout undo deploy/central
