container with maven and docker compose
Full Description

Docker image which includes maven + docker binaries

This image can be used as docker image to run maven builds and create docker images during that build.

As the maven:3-jdk-8 docker image does not include docker binaries
mvn package docker:build will fail. Therefor I modified the container and installed the docker binaries.

This excellent article from jpetazzo
describes why it is not recommended to run docker within docker for CI servers. Instead he suggests to run docker with
docker run -v /var/run/docker.sock:/var/run/docker.sock ... to give the container access to the Docker socket and
therefor is able to start containers.

This can also be used with the gitlab runner executing the ci jobs. All we need to do is to update the `
~/.gitlab-runner/config.toml file. The important part is the volume declaration.

[[runners]]
  ...
  [runners.docker]
    host = "tcp://192.168.99.100:2376"
    tls_cert_path = "/Users/twalter/.docker/machine/machines/default"
    tls_verify = true
    image = "twalter/mvn-docker"
    privileged = false
    volumes = ["/cache","/var/run/docker.sock:/var/run/docker.sock"]

How to run this container?

docker run -v /var/run/docker.sock:/var/run/docker.sock -it twalter/maven-docker /bin/bash
