Root Cause

Init container exits with non-zero status. Main containers won't start until all init containers complete successfully.

generic

Workarounds

  1. 92% success Check init container logs to find the failure reason 
    kubectl logs <pod> -c <init-container-name> to see why it failed

    Sources: https://kubernetes.io/docs/tasks/debug/debug-application/debug-init-containers/

  2. 88% success Verify init container dependencies are available (database, service, config) 
    Common pattern: init container waits for a service. Check if the dependency service exists and is reachable

    Sources: https://kubernetes.io/docs/concepts/workloads/pods/init-containers/#understanding-init-containers

Dead Ends

Common approaches that don't work:

  1. Skip the init container by moving its logic to the main container 65% fail

    Init containers exist for a reason — race conditions and dependency ordering break without them

  2. Delete and recreate the pod repeatedly 85% fail

    Init container will fail again with the same config — underlying issue isn't resolved
