Troubleshooting

Sometimes things go wrong. This guide is aimed at making them right. It has two sections:

• Troubleshooting your application - Useful for users who are deploying code into Kubernetes and wondering why it is not working.
• Troubleshooting your cluster - Useful for cluster administrators and people whose Kubernetes cluster is unhappy.

You should also check the known issues for the release you're using.

Getting help

If your problem isn't answered by any of the guides above, there are variety of ways for you to get help from the Kubernetes community.

Questions

The documentation on this site has been structured to provide answers to a wide range of questions. Concepts explain the Kubernetes architecture and how each component works, while Setup provides practical instructions for getting started. Tasks show how to accomplish commonly used tasks, and Tutorials are more comprehensive walkthroughs of real-world, industry-specific, or end-to-end development scenarios. The Reference section provides detailed documentation on the Kubernetes API and command-line interfaces (CLIs), such as kubectl.
