Jenkins 1.642.2
docker-custom-build-environment:1.6.5
The following error happened in my environment which cannot connect to index.docker.io.
$ docker run --rm --entrypoint /bin/true alpine:3.2 Unable to find image 'alpine:3.2' locally Pulling repository docker.io/library/alpine docker: Error while pulling image: Get https://index.docker.io/v1/repositories/library/alpine/images: dial tcp 54.152.78.181:443: getsockopt: connection refused.

It seems that the following pull request is cause of this bug.
https://github.com/jenkinsci/docker-custom-build-environment-plugin/pull/36
The plugin was modified to use external image "alpine:3.2". However, this change is backward incompatible for environments in internal network with private docker registry.
It is internal specification that the plugin uses the image, though building "alpine:3.2" image in a build environment can be a workaround. I think there should be a config option to specify the image for "/sbin/ip".
