25.08 version update guide

This guide illustrates, step by step, how to update to 25.8.0 from previous versions.

• Uninstall you current mariadb-enterprise-operator for preventing conflicts:

helm uninstall mariadb-enterprise-operator

Alternatively, you may only downscale and delete the webhook configurations:

kubectl scale deployment mariadb-enterprise-operator --replicas=0
kubectl scale deployment mariadb-enterprise-operator-webhook --replicas=0
kubectl delete validatingwebhookconfiguration mariadb-enterprise-operator-webhook
kubectl delete mutatingwebhookconfiguration mariadb-enterprise-operator-webhook

• Upgrade mariadb-enterprise-operator-crds to 25.8.0:

helm repo update mariadb-enterprise-operator
helm upgrade --install mariadb-enterprise-operator-crds  mariadb-enterprise-operator/mariadb-enterprise-operator-crds --version 25.8.0

• The Galera data-plane must be updated to the 25.8.0 version.

If you want the operator to automatically update the data-plane (i.e. init and agent containers), you can set updateStrategy.autoUpdateDataPlane=true in your MariaDB resources:

apiVersion: enterprise.mariadb.com/v1alpha1
kind: MariaDB
metadata:
  name: mariadb-galera
spec:
  updateStrategy:
+   autoUpdateDataPlane: true

Alternatively, you can also do this manually:

apiVersion: enterprise.mariadb.com/v1alpha1
kind: MariaDB
metadata:
  name: mariadb
spec:
  galera:
    agent:
-      image: docker.mariadb.com/mariadb-enterprise-operator:1.0.0
+      image: docker.mariadb.com/mariadb-enterprise-operator:25.8.0
    initContainer:
-      image: docker.mariadb.com/mariadb-enterprise-operator:1.0.0
+      image: docker.mariadb.com/mariadb-enterprise-operator:25.8.0

• Upgrade mariadb-enterprise-operator to 25.8.0:

helm repo update mariadb-enterprise-operator
helm upgrade --install mariadb-enterprise-operator mariadb-enterprise-operator/mariadb-enterprise-operator --version 25.8.0 

• If you previously decided to downscale the operator, make sure you upscale it back:

kubectl scale deployment mariadb-enterprise-operator --replicas=1
kubectl scale deployment mariadb-enterprise-operator-webhook --replicas=1

• If you previously set updateStratety.autoUpdateDataPlane=true, you may consider reverting the changes once the upgrades have finished:

apiVersion: enterprise.mariadb.com/v1alpha1
kind: MariaDB
metadata:
  name: mariadb-galera
spec:
  updateStrategy:
+   autoUpdateDataPlane: false
-   autoUpdateDataPlane: true
