votes

I am using the docker-custom-build-environment-plugin (https://wiki.jenkins-ci.org/display/JENKINS/CloudBees+Docker+Custom+Build+Environment+Plugin) to build a maven job inside a docker container.

I have done the following setup as shown in this image: enter image description here

This is the result in the console log:

$ docker inspect maven:3.3.3-jdk-8

The advice from https://www.cloudbees.com/blog/templating-jenkins-build-environments-docker-containers on using their plugin is to base your slaves off evarga/jenkins-slave

The Dockerfile that you've based it off has some key differences such as the creation of the creation of the jenkins user and starting the sshd daemon. So if you're going to start off from your own image, base it off the evarga image first.
