Authenticate to Docker Hub so that you can get higher pull rate limits.

oc create secret docker-registry docker-hub \ \
  --docker-username=youhoo \

oc secrets link default docker-hub --for=pull,mount
oc secrets link builder docker-hub --for=pull,mount

If you still get ImagePullBackOff and all that crap:

  • Find out which ServiceAccount your app is using: oc get deploy -o yaml then look for serviceAccount and make sure you’ve linked the Secret to the correct ServiceAccount.
  • Check that the secret has been linked to the ServiceAccount correctly: oc get sa default -o yaml - the registry secret should be listed in the list of secrets and imagePullSecrets.
