kubectl cordon

Mark a node as unschedulable, preventing new pods from being assigned to it. See also: kubectl uncordon. More information: https://kubernetes.io/docs/reference/kubectl/generated/kubectl_cordon/.

• Mark a node as unschedulable:

kubectl cordon {{node_name}}

• Mark multiple nodes as unschedulable:

kubectl cordon {{node_name1 node_name2 ...}}

• Mark a node as unschedulable in a specific context:

kubectl cordon {{node_name}} --context {{context_name}}

• Mark nodes matching a label selector as unschedulable:

kubectl cordon {{[-l|--selector]}} {{label_key}}={{label_value}}

• Preview the changes without actually cordoning the nodes (dry run):

kubectl cordon {{node_name}} --dry-run={{none|server|client}}
