However, there can be frustrating moments, such as when your log outputs don’t show what you expect. One common error users encounter is the dreaded "Error from server (NotFound): pods 'install-ingress' not found". If you've found yourself in this situation, don’t worry!

The primary reason for this error is that Kubernetes commands often assume the default namespace unless otherwise specified. In your case, the install-ingress pod is located in the gitlab-managed-apps namespace, but since you did not provide the namespace in your kubectl logs command, Kubernetes was searching for the pod in the default namespace, where it does not exist. The Solution Specifying the Namespace To successfully access the logs of the install-ingress pod, you need to include the -n flag followed by the namespace name in your command. Here's how to do it: [[See Video to Reveal this Text or Code Snippet]] Key Takeaways Always check the namespace: When working with multiple namespaces in Kubernetes, remember to specify the namespace when pulling logs for pods. Default Namespace: If the namespace is not specified, commands will use the default namespace. Therefore, always verify where your pods are located using the kubectl get pods --all-namespaces command. Correct command: Use the format kubectl logs -f POD_NAME -n NAMESPACE to fetch logs from any specific namespace. Conclusion The "pod not found" error you experienced is a common hurdle in Kubernetes administration, but with the right approach, it can be easily resolved. Remember to always specify the namespace when you are working with resources that are not in the default namespace. Now, with this knowledge, you can confidently navigate your Kubernetes pods and access the logs you need without issues. By keeping these tips in mind, you'll be able to troubleshoot similar issues in the future with greater ease. Happy Kubernetes management!
