    Pause/resume Percona XtraDB Cluster¶

    There may be external situations when it is needed to shutdown the Percona XtraDB Cluster for a while and then start it back up (some works related to the maintenance of the enterprise infrastructure, etc.).

    The deploy/cr.yaml file contains a special spec.pause key for this. Setting it to true gracefully stops the cluster:

    spec:
      .......
      pause: true
    

    Pausing the cluster may take some time, and when the process is over, you will see only the Operator Pod running:

    $ kubectl get pods
    NAME                                               READY   STATUS    RESTARTS   AGE
    percona-xtradb-cluster-operator-79966668bd-rswbk   1/1     Running   0          12m
    

    To start the cluster after it was shut down just revert the spec.pause key to false.

    Starting the cluster will take time. The process is over when all Pods have reached their Running status:

    NAME                                               READY   STATUS    RESTARTS   AGE
    cluster1-haproxy-0                                 2/2     Running   0          6m17s
    cluster1-haproxy-1                                 2/2     Running   0          4m59s
