What is it?

Opinionated docker image based on the Debian docker image debian:stable-slim to build native Linux binaries from Java Maven projects using GraalVM native-image feature.

The image comes pre-installed with latest releases of:

• Apache Maven
• bash-funk Bash toolbox with adaptive Bash prompt
• Docker CE command line client
• git command line client
• GraalVM Java 17 with native-image extension.
• upx executable packer

Usage

Building a local Maven project

To build a Maven project located on your local workstation with via this docker image you can do:

1. On Linux:

   $ cd ~/myproject
   $ docker run --rm -it \
     -v $PWD:/mnt/myproject:rw \
     -w /mnt/myproject \
     wiradikusuma/graalvm-maven-for-quarkus:latest-java17 \
     mvn clean package

2. On Windows:

   C:> cd C:\Users\MyUser\myproject
   C:\Users\MyUser\myproject> docker run --rm -it ^
     -v /c/Users/MyUser/myproject:/mnt/myproject:rw ^
     -w /mnt/myproject ^
     wiradikusuma/graalvm-maven-for-quarkus:latest-java17 ^
     mvn clean package

Also checkout the example project which provides convenient batch/bash script wrappers and outlines how to do compile Java projects to native Linux binaries.

Using custom Maven settings.xml

You can use a custom Maven settings.xml by mounting it to /root/.m2/settings.xml

    $ cd ~/myproject
    $ docker run --rm -it \
      -v /path/to/my/settings.xml:/root/.m2/settings.xml:ro \
      -v $PWD:/mnt/myproject:rw \
      -w /mnt/myproject \
      wiradikusuma/graalvm-maven-for-quarkus:latest-java17 \
      mvn clean package

Running docker commands inside the container

This image has the docker command line client installed, which allows you to run other docker containers as part of your build toolchain using a docker-out-of-docker (DooD) approach by mounting the /var/run/docker.sock into the container.

$ cd ~/myproject
$ docker run --rm -it \
  -v /var/run/docker.sock:/var/run/docker.sock:rw \
  -v $PWD:/mnt/myproject:rw \
  wiradikusuma/graalvm-maven-for-quarkus:latest-java17 \
  docker run --rm hello-world

Caching local Maven repository between runs

You can a local folder to /root/.m2/repository to cache the downloaded artifacts between Maven runs

    $ cd ~/myproject
    $ docker run --rm -it \
      -v /path/to/my/local/repository:/root/.m2/repository:rw \
      -v $PWD:/mnt/myproject:rw \
      -w /mnt/myproject \
      wiradikusuma/graalvm-maven-for-quarkus:latest-java17 \
      mvn clean package
