Top 5 Kubernetes Errors and How to Fix Them Like a Pro

Here is detailed description with troubleshooting tips:

1. Resource Exhausted Error: Occurs when pods exceed allocated CPU or memory resources.​
2. CrashLoopBackOff: Pods crash repeatedly due to application errors or misconfigurations.
3. ImagePullBackOff: Kubernetes fails to pull container images, often due to incorrect image names or authentication issues.​
4. Pending Pods: Pods remain unscheduled because of insufficient resources or node selector constraints.​
5. Service Not Found: Services are unreachable due to misconfigurations or missing endpoints.​

Troubleshooting Tips:

• Use kubectl describe pod <pod-name> to inspect pod events and identify issues.​
• Check container logs with kubectl logs <pod-name> for error messages.​
• Monitor resource usage using kubectl top pod and kubectl top node.​
• Verify service configurations and endpoints with kubectl get svc and kubectl get endpoints.​
• Adjust resource requests and limits in deployment specifications to prevent resource exhaustion.​
  

By systematically addressing these common errors, you can enhance the stability and reliability of your Kubernetes deployments.
