      Description

      Steps to Reproduce:

      1. With the above installed, create a job with "Execute Docker command" which does:

      Pull Image

      Name: owasp/zap2docker-weekly
      Tag: latest
      Registry: [blank[ or Docker
      Docker Registry URL; https://hub.docker.com/r/owasp/zap2docker-weekly/
      Registry Credentials: [none]

      2. In Jenkins, click "Build Now"

      Actual Results:

      I get the following stack trace/exception:

          This ended up being my mistake, of course - I hadn't specified the Docker REST API url/endpoint.
