How do I troubleshoot my Kubernetes deployment issues?

To troubleshoot Kubernetes deployment issues, start by checking the status of your pods using kubectl get pods. What specific issues are you facing?

Some of my pods are in a CrashLoopBackOff state. What does that mean?

A CrashLoopBackOff means that your pod is crashing repeatedly. You can check the logs with kubectl logs <pod-name> to see what’s causing the crash.

I checked the logs, and it says there's a missing environment variable. How can I fix that?

You can update your deployment to include the missing environment variable. Use kubectl edit deployment <deployment-name> to modify it.

Thanks! How can I apply the changes without downtime?

You can use rolling updates by updating the deployment with kubectl apply -f <deployment-file.yaml>. This will ensure zero downtime.
