docker-plugin: Registry Credentials Not Used To Pull (build step)

Jobs that are configured to use a “Build / Publish Docker Image” build step with registry credentials do not appear to be using the credentials when pulling the parent image (the “FROM” in the Dockerfile).

Plugin version: 1.1.1 Jenkins version: 2.89.2 Docker version: 1.13.1 Docker API Jenkins plugin version: 3.0.14

Console output says:

15:43:06 Docker Build

I’m not sure if the plugin is passing the credentials to the API plugin or not. If it is and the issue is really withe API plugin please let me know and I’ll open the issue over there.
