Errors

ImagePullBackOff

Container running a pod fails to pull the required image from a container registry.

• When a pod is created, k8s attempts to pull the container image specified in the pod definition from the container registry
  • IF the image is not available or cannot be pulled, k8s stops pulling image and pod will remain in a pending state
    • Root cause could be network connectivity, image name/tag, credential freshness, permissions issues
