You can upgrade to the latest version of Red Hat Advanced Cluster Security for Kubernetes from a supported older version.

To upgrade Red Hat Advanced Cluster Security for Kubernetes to the latest version, you must perform the following:

  • Backup the Central database

  • Upgrade Central

  • Upgrade the roxctl CLI

  • Upgrade Scanner

  • Verify that all secured clusters are upgraded

Backing up the Central database

You can back up the Central database and use that backup for rolling back from a failed upgrade or data restoration in the case of an infrastructure disaster.

Prerequisites
  • You must have an API token with read permission for all resources of Red Hat Advanced Cluster Security for Kubernetes. The Analyst system role has read permissions for all resources.

  • You have installed the roxctl CLI.

  • You have configured the ROX_API_TOKEN and the ROX_CENTRAL_ADDRESS environment variables.

Procedure
  • Run the backup command:

    • For Red Hat Advanced Cluster Security for Kubernetes 3.0.55 and newer:

      $ roxctl -e "$ROX_CENTRAL_ADDRESS" central backup
    • For Red Hat Advanced Cluster Security for Kubernetes 3.0.54 and older:

      $ roxctl -e "$ROX_CENTRAL_ADDRESS" central db backup

Upgrading the Central cluster

After you have backed up the Central database, the next step is to upgrade the Central cluster. This step includes upgrading Central, the roxctl CLI, and the Scanner.

Upgrading Central

You can update Central to the latest version by downloading and deploying the updated images.

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"}}}]}]}}}}' (1)
    1 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}}]}}}}' (1)
    1 If you use Kubernetes, enter kubectl instead of oc.
    $ oc -n stackrox set image deploy/central central=registry.redhat.io/advanced-cluster-security/rhacs-main-rhel8:3.71.3 (1)
    1 If you use Kubernetes, enter kubectl instead of oc.
    • 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"]}]}' (1)
      1 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 '
      {
      "metadata": {
      "annotations": {
      "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"}}"
      }
      }
      }'
Verification
  • Check that the new pods have deployed:

    $ oc get deploy -n stackrox -o wide (1)
    1 If you use Kubernetes, enter kubectl instead of oc.
    $ oc get pod -n stackrox --watch (1)
    1 If you use Kubernetes, enter kubectl instead of oc.

After you upgrade the roxctl CLI you can upgrade Scanner.

Upgrading Scanner

You can update Scanner to the latest version by using the roxctl CLI.

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.

Procedure
  1. If you have created custom scanner configurations, you must apply those changes before updating the scanner configuration file.

    1. Generate Scanner using the following roxctl command:

      $ roxctl -e "$ROX_CENTRAL_ADDRESS" scanner generate
    2. Apply the TLS secrets YAML file:

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

        $ oc apply -f scanner-bundle/scanner/02-scanner-03-tls-secret.yaml
      • If you use Kubernetes, enter the following command:

        $ kubectl apply -f scanner-bundle/scanner/02-scanner-03-tls-secret.yaml
    3. Apply the Scanner configuration YAML file:

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

        $ oc apply -f scanner-bundle/scanner/02-scanner-04-scanner-config.yaml
      • If you use Kubernetes, enter the following command:

        $ kubectl apply -f scanner-bundle/scanner/02-scanner-04-scanner-config.yaml
  2. Update the Scanner image:

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

      $ oc -n stackrox set image deploy/scanner scanner=registry.redhat.io/advanced-cluster-security/rhacs-scanner-rhel8:3.71.3
    • If you use Kubernetes, enter the following command:

      $ kubectl -n stackrox set image deploy/scanner scanner=registry.redhat.io/advanced-cluster-security/rhacs-scanner-rhel8:3.71.3
  3. Update the Scanner database image:

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

      $ oc -n stackrox set image deploy/scanner-db db=registry.redhat.io/advanced-cluster-security/rhacs-scanner-db-rhel8:3.71.3 init-db=registry.redhat.io/advanced-cluster-security/rhacs-scanner-db-rhel8:3.71.3
    • If you use Kubernetes, enter the following command:

      $ kubectl -n stackrox set image deploy/scanner-db db=registry.redhat.io/advanced-cluster-security/rhacs-scanner-db-rhel8:3.71.3 init-db=registry.redhat.io/advanced-cluster-security/rhacs-scanner-db-rhel8:3.71.3
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

Upgrading to RHACS version 3.71

If you are upgrading to RHACS 3.71 using the roxctl CLI and YAML files, you need to perform some additional steps. The Scanner DB image no longer mounts the scanner-db-password Kubernetes Secret into the db Scanner DB container. Instead, scanner-db-password is only used in the init container, init-db. Therefore, you must add the POSTGRES_PASSWORD_FILE environment variable to the init container configuration. The init container must also mount the scanner-db-tls-volume and scanner-db-password volumes. The following section provides the upgrade steps for RHACS if you are using OpenShift Container Platform or Kubernetes. For more information about init containers, see the Kubernetes documentation.

Prerequisites
  • This procedure assumes the db container in the Scanner DB configuration is at index 0, which is the first entry in the containers list; and the scanner-db-password volume mount is at index 2, which is the third entry.

While this scenario applies to most deployments, check the configuration for Scanner DB before entering these commands. If your values differ, you must adjust the …​/containers/x/volumeMounts/y value in the following commands.

Procedure
  1. Apply the patch:

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

      $ oc -n stackrox patch deployment.apps/scanner-db --patch '{"spec":{"template":{"spec":{"initContainers":[{"name":"init-db","env":[{"name":"POSTGRES_PASSWORD_FILE","value":"/run/secrets/stackrox.io/secrets/password"}],"command":["/usr/local/bin/docker-entrypoint.sh","postgres","-c","config_file=/etc/postgresql.conf"],"volumeMounts":[{"name":"db-data","mountPath":"/var/lib/postgresql/data"},{"name":"scanner-db-tls-volume","mountPath":"/run/secrets/stackrox.io/certs","readOnly":true},{"name":"scanner-db-password","mountPath":"/run/secrets/stackrox.io/secrets","readOnly":true}],"securityContext":{"runAsGroup":70,"runAsNonRoot":true,"runAsUser":70}}]}}}}'
    • If you use Kubernetes, enter the following command:

      $ kubectl -n stackrox patch deployment.apps/scanner-db --patch '{"spec":{"template":{"spec":{"initContainers":[{"name":"init-db","env":[{"name":"POSTGRES_PASSWORD_FILE","value":"/run/secrets/stackrox.io/secrets/password"}],"command":["/usr/local/bin/docker-entrypoint.sh","postgres","-c","config_file=/etc/postgresql.conf"],"volumeMounts":[{"name":"db-data","mountPath":"/var/lib/postgresql/data"},{"name":"scanner-db-tls-volume","mountPath":"/run/secrets/stackrox.io/certs","readOnly":true},{"name":"scanner-db-password","mountPath":"/run/secrets/stackrox.io/secrets","readOnly":true}],"securityContext":{"runAsGroup":70,"runAsNonRoot":true,"runAsUser":70}}]}}}}'
  2. Remove the path:

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

      $ oc -n stackrox patch deployment.apps/scanner-db --type json --patch '[{"op":"remove","path":"/spec/template/spec/containers/0/volumeMounts/2"}]'
    • If you use Kubernetes, enter the following command:

      $ kubectl -n stackrox patch deployment.apps/scanner-db --type json --patch '[{"op":"remove","path":"/spec/template/spec/containers/0/volumeMounts/2"}]'

Verifying the Central cluster upgrade

After you have upgraded both Central and Scanner, verify that the Central cluster upgrade is complete.

Procedure
  • Check the Central logs:

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

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

    If you are using Kubernetes, enter the following command:

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

Upgrading all secured clusters

After upgrading Central services, you must upgrade all secured clusters.

  • If you are using automatic upgrades:

    • Update all your secured clusters by using automatic upgrades.

    • Skip the instructions in this section and follow the instructions in the Verify upgrades and Revoking the API token sections.

  • If you are not using automatic upgrades, you must run the instructions in this section on all secured clusters including the Central cluster.

    • To ensure optimal functionality, use the same RHACS version for your secured clusters and the cluster on which Central is installed.

To complete manual upgrades of each secured cluster running Sensor, Collector, and Admission Controller, follow the instructions in this section.

Update readiness probes

If you are upgrading from a version below Red Hat Advanced Cluster Security for Kubernetes 3.65.0, you must run the following additional command to update the readiness probe path. If you are running a higher version than 3.65, skip this step.

Procedure
  • Update the readiness probe path:

    $ oc -n stackrox patch deploy/sensor -p '{"spec":{"template":{"spec":{"containers":[{"name":"sensor","readinessProbe":{"httpGet":{"path":"/ready"}}}]}}}}' (1)
    1 If you use Kubernetes, enter kubectl instead of oc.

Updating OpenShift security context constraints

Depending on the version of Red Hat Advanced Cluster Security for Kubernetes you are upgrading to, you must update certain OpenShift Container Platform security context constraints (SCCs).

Run the commands in this section only if you are using Red Hat Advanced Cluster Security for Kubernetes with OpenShift Container Platform. Otherwise, skip the instructions in this section.

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:

    1. Run the following commands to update Central:

Updating other images

You must update the sensor, collector and compliance images on each secured cluster when not using automatic upgrades.

If you are using Kubernetes, use kubectl instead of oc for the commands listed in this procedure.

Procedure
  1. Update the Sensor image:

    $ oc -n stackrox set image deploy/sensor sensor=registry.redhat.io/advanced-cluster-security/rhacs-main-rhel8:3.71.3 (1)
    1 If you use Kubernetes, enter kubectl instead of oc.
  2. Update the Compliance image:

    $ oc -n stackrox set image ds/collector compliance=registry.redhat.io/advanced-cluster-security/rhacs-main-rhel8:3.71.3 (1)
    1 If you use Kubernetes, enter kubectl instead of oc.
  3. Update the Collector image:

    $ oc -n stackrox set image ds/collector collector=registry.redhat.io/advanced-cluster-security/rhacs-collector-rhel8:3.71.3 (1)
    1 If you use Kubernetes, enter kubectl instead of oc.

    If you are using the collector slim image, run the following command instead:

    $ oc -n stackrox set image ds/collector collector=registry.redhat.io/advanced-cluster-security/rhacs-collector-slim-rhel8:{rhacs-version}
  4. Update the admission control image:

    $ oc -n stackrox set image deploy/admission-control admission-control=registry.redhat.io/advanced-cluster-security/rhacs-main-rhel8:3.71.3

Verifying secured cluster upgrade

After you have upgraded secured clusters, verify that the updated pods are working.

Procedure
  • Check that the new pods have deployed:

    $ oc get deploy,ds -n stackrox -o wide (1)
    1 If you use Kubernetes, enter kubectl instead of oc.
    $ oc get pod -n stackrox --watch (1)
    1 If you use Kubernetes, enter kubectl instead of oc.

Rolling back Central

You can roll back to a previous version of Central if the upgrade to a new version is unsuccessful.

Rolling back Central normally

You can roll back to a previous version of Central if upgrading Red Hat Advanced Cluster Security for Kubernetes fails.

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 (1)
    1 If you use Kubernetes, enter kubectl instead of oc.

Rolling back Central forcefully

You can use forced rollback to roll back to an earlier version of Central (after the Central service starts).

Using forced rollback to switch back to a previous version might result in loss of data and functionality.

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 (1)
      1 If you use Kubernetes, enter kubectl instead of oc.
    • To forcefully rollback to a specific version:

      1. Edit Central’s ConfigMap:

        $ oc -n stackrox edit configmap/central-config (1)
        1 If you use Kubernetes, enter kubectl instead of oc.
      2. Update the value of the maintenance.forceRollbackVersion key:

        data:
          central-config.yaml: |
            maintenance:
              safeMode: false
              compaction:
                 enabled: true
                 bucketFillFraction: .5
                 freeFractionThreshold: 0.75
              forceRollbackVersion: <x.x.x.x> (1)
          ...
        1 Specify the version that you want to roll back to.
      3. Update the Central image version:

        $ oc -n stackrox \ (1)
          set image deploy/central central=registry.redhat.io/advanced-cluster-security/rhacs-main-rhel8:<x.x.x.x> (2)
        
        1 If you use Kubernetes, enter kubectl instead of oc.
        2 Specify the version that you want to roll back to. It must be the same version that you specified for the maintenance.forceRollbackVersion key in the central-config config map.

Verifying upgrades

The updated Sensors and Collectors continue to report the latest data from each secured cluster.

The last time Sensor contacted Central is visible in the RHACS portal.

Procedure
  1. On the RHACS portal, navigate to Platform ConfigurationSystem Health.

  2. Check to ensure that Sensor Upgrade shows clusters up to date with Central.

Revoking the API token

For security reasons, Red Hat recommends that you revoke the API token that you have used to complete Central database backup.

Prerequisites
  • After the upgrade, you must reload the RHACS portal page and re-accept the certificate to continue using the RHACS portal.

Procedure
  1. On the RHACS portal, navigate to Platform ConfigurationIntegrations.

  2. Scroll down to the Authentication Tokens category, and click API Token.

  3. Select the checkbox in front of the token name that you want to revoke.

  4. Click Revoke.

  5. On the confirmation dialog box, click Confirm.
