Docker, perfect for test-driving Jenkins

When Jenkins 2.0 was released I wanted to take it for a test drive, the perfect way to do this was through Docker. Docker means zero commitment to installing packages and configuring your system. Even installing Java could take you on a 30-60min hour detour, Official, prebuilt images in the Docker Hub completely eliminates that and gives you near instant access to pre-packaged software.

I started off by looking at the official instructions for starting a Jenkins 2.0 container. They give 3-4 variations of the docker run command but this can be made much simpler through the use of Docker Compose and a docker-compose.yml file.

Jenkins Slave Docker images:

You can pull these images straight from the public Docker Hub to be used as Jenkins slave agents.

Jenkins slave images have been trimmed down to 150mb from 650mb+ by switching to Alpine Linux.
