Drainage Tasks

Check Items

An unfinished drainage task is detected in the cluster, which may resume after the upgrade. If this happens, running pods will be evicted, which could impact your services.

Solution

1. Configure the kubectl command. For details, see Connecting to a Cluster Using kubectl.
2. Check if there are any drainage tasks in progress.

   kubectl get drainage

   Delete the drainage resources and perform the pre-upgrade check again.

3. Run the following command to delete a drainage task:

   kubectl delete drainage {Name of the drainage task}
