Container repeatedly restarting
Back-off restarting failed container|restartCount:\s*[5-9]|restartCount:\s*\d{2,}
Fixes
- 1.Check previous container logs: kubectl logs pod --previous
- 2.Inspect exit code: kubectl describe pod name (look for Exit Code)
- 3.Verify environment variables and secrets are set correctly
- 4.Check if the container exits immediately due to wrong CMD
