Suspend Reconciliation

Instructions on how to temporarily pause the Operator's automated management of a specific resource for maintenance or troubleshooting.

Suspended state

When a resource is suspended, all operations performed by the operator are disabled, including but not limited to:

• Provisioning

• Upgrades

• Volume resize

• Galera cluster recovery

More specifically, the reconciliation loop of the operator is omitted, anything part of it will not happen while the resource is suspended. This could be useful in maintenance scenarios, where manual operations need to be performed, as it helps prevent conflicts with the operator.

Suspend a resource

Currently, only MariaDB and MaxScale resources support suspension. You can enable it by setting suspend=true:

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

This results in the reconciliation loop being disabled and the status being marked as Suspended:

kubectl get mariadbs
NAME             READY   STATUS      PRIMARY           UPDATES                   AGE
mariadb-galera   True    Suspended   mariadb-galera-0  ReplicasFirstPrimaryLast  12m

To re-enable it, simply remove the suspend setting or set it to suspend=false.
