kubernetes — error
# Init container failed
Init container failed

What this error means

Init containers run sequentially before the main application containers start. If any init container fails, Kubernetes stops the Pod startup and restarts the init sequence (respecting restart policy). Common failures include command errors, missing dependencies, permission issues, or failed health checks.

Typical symptoms

  • Pod stuck in "Init:0/N" or "InitContainerCrashLoopBackOff" state
  • Pod events show init container exit with error code
  • kubectl logs shows init container failure
  • Application never starts due to init failure
  • Init container cannot find required files or commands
  • Network or storage not ready when init runs
  • Previous init containers completed but next one fails

Common causes

  1. Init container command has syntax error or wrong binary
  2. Required files or volumes not present when init runs
  3. Permission denied accessing files or directories
  4. Dependency service not available or not responding
  5. Init container image missing required tools
  6. Volume mount not ready when init container starts
  7. Environment variables not set correctly
  8. Init container exit code indicates application-specific error

Advanced notes

Init containers sequential. One failure stops rest. Exit code 0 required for success. Use shared volumes for data passing.
