Chapter 2. Manually upgrading using the roxctl CLI
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
2.1. Backing up the Central database Copia collegamentoCollegamento copiato negli appunti!
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 hasread
permissions for all resources. -
You have installed the
roxctl
CLI. -
You have configured the
ROX_API_TOKEN
and theROX_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
$ roxctl -e "$ROX_CENTRAL_ADDRESS" central backup
Copy to Clipboard Copied! Toggle word wrap Toggle overflow For Red Hat Advanced Cluster Security for Kubernetes 3.0.54 and older:

2.2.3.1. Upgrading to RHACS version 3.71 Copia collegamentoCollegamento copiato negli appunti!
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 atindex 0
, which is the first entry in thecontainers
list; and thescanner-db-password
volume mount is atindex 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
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}}]}}}}'

2.3. Upgrading all secured clusters Copia collegamentoCollegamento copiato negli appunti!
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.
2.3.1. Update readiness probes Copia collegamentoCollegamento copiato negli appunti!
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"}}}]}}}}'
$ oc -n stackrox patch deploy/sensor -p '{"spec":{"template":{"spec":{"containers":[{"name":"sensor","readinessProbe":{"httpGet":{"path":"/ready"}}}]}}}}'

2.3.2. Updating OpenShift security context constraints Copia collegamentoCollegamento copiato negli appunti!
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:

2.4. Rolling back Central Copia collegamentoCollegamento copiato negli appunti!
You can roll back to a previous version of Central if the upgrade to a new version is unsuccessful.
2.4.1. Rolling back Central normally Copia collegamentoCollegamento copiato negli appunti!
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

2.4.2. Rolling back Central forcefully Copia collegamentoCollegamento copiato negli appunti!
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

2.5. Verifying upgrades Copia collegamentoCollegamento copiato negli appunti!
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
-
On the RHACS portal, navigate to Platform Configuration
System Health. - Check to ensure that Sensor Upgrade shows clusters up to date with Central.
2.6. Revoking the API token Copia collegamentoCollegamento copiato negli appunti!
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
-
On the RHACS portal, navigate to Platform Configuration
Integrations. - Scroll down to the Authentication Tokens category, and click API Token.
- Select the checkbox in front of the token name that you want to revoke.
- Click Revoke.
- On the confirmation dialog box, click Confirm.
