Evacuating pods is the process of moving all of the pods on a node to another node. Before pods can be evacuated, the node must be marked as unscheduable.
A node contains one or more pods, and each pod contains one or more containers.
The oc adm drain command can be used to evacuate the pods on a node. In this example, the pods on node001 and node002 will be moved to another node.
oc adm drain node001 node002
