Requirements for Jenkins agent in docker container

[Zach LaCelle]

Hello,

What does Jenkins need to run jobs in a Docker container? I know that the jenkinsci/slave Docker image works, but if I want to create a new image based off of a different origin, what process, environment variables, etc need to be running?

This would be using the "Docker Attach" methodology, but I assume the list is similar for SSH (minus the SSH server).

For example, looks like it needs:

* openjdk 8

* a Jenkins user/group

* slave.jar at /usr/share/jenkins/slave.jar

* /home/jenkins/.jenkins

* /home/jenkins/agent

* WORKDIR set to /home/jenkins

* ENV AGENT_WORKDIR set to /home/jenkins/agent
