Have you applied to dockerhub to exempt the openwhisk org from their new-ish rate limiting? Travis tests (or any tests on a shared infrastructure) will begin to routinely fail because of this: > > docker: toomanyrequests: You have reached your pull rate limit. You may > increase the limit by authenticating and upgrading: > https://www.docker.com/increase-rate-limit. > > This, for example, can happen when pulling the openwhisk/standalone image, or any of the action/skeleton base images, as part of automated tests.
