###Jenkins with Docker-in-Docker The Jenkins-with-Docker-in-Docker container image is a standardized continuous integration environment with both Jenkins and Docker-in-Docker. This means it had all the benefits of an easily transportable docker container, plus it then has built in capability to build docker containers from within. It also features CNTLM as a local proxy that can be enabled and configured via the use of environment variables passed in at runtime, this means you can grabs things directly from your local network (with NoProxy) and then also go out to your network proxy for anything else.

####Usage You can build the image with a docker build command, such as:

docker build --rm=true -t your-registry/jenkins:latest

After you have a completed docker image, you can then run with the container with the following run command: (config in square brackets is optional)

sudo docker run -d --name=jenkins --privileged -v /opt/jenkins:/var/jenkins_home \
  [-e DOCKER_OPTS="--dns x.x.x.x"] [-e HTTP_PROXY="x.x.x.x" -e HTTP_PROXY_PORT="xxxx"] \
  [-e NO_PROXY_LIST="localhost, 127.0.0.*, foo.bar, bar.foo"] -p 80:8080 your-registry/jenkins:latest

Note. the /var/jenkins_home volume mount is required for persistant configuration/projects/builds/modules.

####Requirements Unable the pinpoint the exact version, however, the use of docker-in-docker has been known to crash with older host kernels, try to use something newer, such as 3.16+
