image: Image config is empty for gcr.io/google_containers/pause-amd64 #395
Description
When running kubeadm 1.7 on top of CRI-O, as a test for kubeadm tries to start a dummy pod where the pod is made of one single container. The latter is suppose to run the gcr.io/google_containers/pause-amd64:3.0 image which happens to be a pause one:
ocic image status -id ff37f71df8d20abd11690fa791d3e29742a319caa3dc0e0d9d3fc1b976df73df
ID: ff37f71df8d20abd11690fa791d3e29742a319caa3dc0e0d9d3fc1b976df73df
Tag: gcr.io/google_containers/pause-amd64:latest
Tag: gcr.io/google_containers/pause-amd64:3.0
Tag: gcr.io/google_containers/pause-amd64
Size: 751477
Unfortunately, pkg/storage/runtime:createContainerOrPodSandbox() gets an empty blob for that image. When adding some debug to createContainerOrPodSandbox, we see that len(configBlob) is 0 for that specific image.
docker inspect on a gcr.io/google_containers/pause-amd64 gives:
