Maven extended Docker images

This project provide container images that extend official maven images. They are build with S6 overlay to provide :

• wget
• Git
• Docker client

The easiest way to use it is to define wrapper bash functions in .bashrc ou .zshrc that bind mount the needed directories and sets the UID/GID .

docker-mvn() (
  docker run --rm -it \
    --env S6_LOGGING=1 \
    --env S6_BEHAVIOUR_IF_STAGE2_FAILS \
    --volume "${HOME}/.m2":"/home/user/.m2" \
    --volume "${HOME}/.ssh":"/home/user/.ssh" \
    --volume "${HOME}/.gitconfig":"/home/user/.gitconfig" \
    --volume "$(pwd)":"/usr/src/mymaven" \
    --workdir /usr/src/mymaven \
    --env PUID="$(id -u)" -e PGID="$(id -g)" \
    --env MAVEN_CONFIG=/home/user/.m2 \
    "${MAVEN_IMAGE:-"brunoe/maven"}" \
    runuser --user user \
    --group user \
    -- mvn --errors --threads 1C --color always --strict-checksums \
    -Duser.home=/home/user \
    "$@"
)

docker-mvn-8() (MAVEN_IMAGE=brunoe/maven:8 docker-mvn $@)
docker-mvn-11() (MAVEN_IMAGE=brunoe/maven:11 docker-mvn $@)
docker-mvn-17() (MAVEN_IMAGE=brunoe/maven:17 docker-mvn $@)
docker-mvn-19() (MAVEN_IMAGE=brunoe/maven:19 docker-mvn $@)

It can then used in place of the mvn command without need to installe Java or Maven.
