Restart

  1. Restart a cluster.

    kubectl apply -f - <<EOF
apiVersion: apps.kubeblocks.io/v1alpha1
kind: OpsRequest
metadata:
  name: mycluster-restart
  namespace: demo
spec:
  clusterName: mycluster
  type: Restart
  restart:
  - componentName: be
EOF

  2. Check the pod and operation status to validate the restarting.

    kubectl get pod -n demo

kubectl get ops ops-restart -n demo

    During the restarting process, there are two status types for pods.

    • STATUS=Terminating: it means the cluster restart is in progress.
    • STATUS=Running: it means the cluster has been restarted.

  1. Configure the values of components and ttlSecondsAfterSucceed and run the command below to restart a specified cluster.

    kbcli cluster restart mycluster -n demo --components="starrocks" --ttlSecondsAfterSucceed=30
    • components describes the component name that needs to be restarted.
    • ttlSecondsAfterSucceed describes the time to live of an OpsRequest job after the restarting succeeds.

  2. Validate the restarting.

    Run the command below to check the cluster status to check the restarting status.

    kbcli cluster list mycluster -n demo
>
NAME        NAMESPACE   CLUSTER-DEFINITION     VERSION             TERMINATION-POLICY   STATUS    CREATED-TIME
mycluster   demo        starrocks               starrocks-3.1.1    Delete               Running   Jul 17,2024 19:06 UTC+0800
    • STATUS=Updating: it means the cluster restart is in progress.
    • STATUS=Running: it means the cluster has been restarted.
