Debugging workflow:

  • kubectl get
    • Do I see the resources I expect?
    • What are their states?
  • kubectl describe
    • What are the events?
    • Does the describe line up with your manifest?
  • kubectl logs
    • Are there errors in the logs?
    • Are your requests making it to the application?
  • read manifests
    • Understand the system holistically

Common helpful questions:

  • How do labels work/what are your labels doing?
  • Can you trace a request from your laptop to the application?
