Upgrading the MarkLogic root image to rootless

To upgrade the MarkLogic image from root to rootless:

1. Set the rootToRootlessUpgrade flag in the values.yaml to true:

   Copy

   rootToRootlessUpgrade: true
   

2. Update the image.tag in the values.yaml file to the rootless MarkLogic version to upgrade to:

   Copy

   repository: marklogicdb/marklogic-db
   tag: <11.2.0-ubi-rootless>
   

3. Upgrade the Helm Chart using the helm upgrade command with the release name, chart name, and values.yaml:

   Copy

   helm upgrade <release-name> <chart-name>  -n <release-namespace>
   

4. Use this command to start the upgrade. The command will delete the pod with the smallest ordinal that is a MarkLogic bootstrap host:

   Copy

   kubectl delete pod <pod-name> -n <release-namespace>
   

   For example:

   Copy

   kubectl delete pod dnode-group-marklogic-0
   

5. Once the pod is terminated, a new pod is created with a rootless MarkLogic version. Monitor the pod status with this command:

   Copy

   kubectl get pods --nampespace=<your-namespace> -w
   

6. As soon as all pods are back running, verify the upgrade by checking the permissions on volume mounts or by running the required tests.

   Note:

   If rootToRootlessUpgrade is set to true and the image tag is not rootless, then this error message is displayed:

   ERROR: Root to Rootless Upgrade is supported only if rootToRootlessUpgrade flag is true and image type is rootless.
