Root Cause

Kubernetes cannot pull the container image from the registry.

generic

Workarounds

  1. 93% success Verify image name and tag exist in the registry: docker pull <image> 
    Test from a machine with registry access to confirm image exists
  2. 95% success Create or update imagePullSecrets for private registries 
    kubectl create secret docker-registry regcred --docker-server=... --docker-username=... --docker-password=...

Dead Ends

Common approaches that don't work:

  1. Restarting the kubelet 80% fail

    The issue is authentication or image reference, not the kubelet

  2. Waiting for it to resolve itself 85% fail

    ImagePullBackOff has exponential backoff but won't fix auth issues
