Managing Kubernetes nodes involves several key tasks, including inspecting, labeling, cordoning, draining, and uncordoning nodes. Here’s a brief overview of each:
1. Inspecting Nodes
To view the status and details of nodes:
kubectl get nodes
kubectl describe node <node-name>
2. Labeling Nodes
You can add labels to nodes for organization and scheduling:
kubectl label nodes <node-name> <label-key>=<label-value>
3. Cordon a Node
To prevent new pods from being scheduled on a node:
kubectl cordon <node-name>
4. Drain a Node
To safely evict all pods from a node for maintenance:
kubectl drain <node-name> --ignore-daemonsets
5. Uncordon a Node
To allow scheduling on a previously cordoned node:
kubectl uncordon <node-name>
