Debugging with kubectl¶

Overview¶

kubectl provides several commands that help diagnose problems in Kubernetes clusters.

These commands allow users to inspect resource status, view logs, and interact with running containers.

List cluster resources:

kubectl get pods

List nodes:

kubectl get nodes

List services:

kubectl get services

Inspect Resource Details

View detailed information:

kubectl describe pod <pod-name>

This command shows:

View Logs

Inspect container logs:

kubectl logs <pod-name>

Stream logs in real time:

kubectl logs -f <pod-name>

Run Commands Inside Containers

Open a shell:

kubectl exec -it <pod-name> -- /bin/bash

Run a command:

kubectl exec <pod-name> -- ls

View Cluster Events

Check recent cluster events:

kubectl get events

Events can reveal scheduling failures, image pull issues, and container crashes.
