Prepare the management virtual machines for maintenance
Use this procedure to drain the management virtual machine to safely evict all of your pods before you perform maintenance on the management virtual machine.
Steps
- Log in to the primary management virtual machine.
- Type kubectl get nodes to list all of the nodes.
-
Identify the node scheduled for maintenance from above, and type
kubectl drain <node> --ignore-daemonsets --delete-emptydir-data to drain the node.
The node will cordoned, which will mark the node as unschedulable and prevent the scheduler from placing new pods onto that node.NOTE:PowerFlex Manager could be inaccessible for five to ten minutes.
- Perform maintenance procedures.
- Type kubectl uncordon <node> to uncordon the node.
