Readiness probe failed|Liveness probe failed
Fixes
- 1.Verify the probe endpoint returns 200 when the app is healthy
- 2.Increase initialDelaySeconds if the app needs more startup time
- 3.Check the probe port matches the container's listening port
- 4.Add timeoutSeconds if the health endpoint is slow
