Apache Maven is a software project management and comprehension tool. Based on the concept of a project object model (POM), Maven can manage a project's build, reporting and documentation from a central piece of information.
You can run a Maven project by using the Maven Docker image directly,
passing a Maven command to docker run
:
docker run -it --rm --name my-maven-project -v "$(pwd)":/usr/src/mymaven -w /usr/src/mymaven maven:3.3-jdk-8 mvn clean install
This is a base image that you can extend, so it has the bare minimum packages needed. If you add custom package(s) to the Dockerfile
, then you can build your local Docker image like this:
docker build --tag my_local_maven:3.6.0-jdk-8 .
You can build your application with Maven and package it in an image that does not include Maven using multi-stage builds.
# build
FROM maven
WORKDIR /usr/src/app
COPY pom.xml .
RUN mvn -B -e -C -T 1C org.apache.maven.plugins:maven-dependency-plugin:3.0.2:go-offline
COPY . .
RUN mvn -B -e -o -T 1C verify
# package without maven
FROM openjdk
COPY --from=0 /usr/src/app/target/*.jar ./
The local Maven repository can be reused across containers by creating a volume and mounting it in /root/.m2
.
docker volume create --name maven-repo
docker run -it -v maven-repo:/root/.m2 maven mvn archetype:generate # will download artifacts
docker run -it -v maven-repo:/root/.m2 maven mvn archetype:generate # will reuse downloaded artifacts
Or you can just use your home .m2 cache directory that you share e.g. with your Eclipse/IDEA:
docker run -it --rm -v "$PWD":/usr/src/mymaven -v "$HOME/.m2":/root/.m2 -v "$PWD/target:/usr/src/mymaven/target" -w /usr/src/mymaven maven mvn clean package
The $MAVEN_CONFIG
dir (default to /root/.m2
) could be configured as a volume so anything copied there in a Dockerfile at build time is lost.
For that reason the dir /usr/share/maven/ref/
exists, and anything in that directory will be copied on container startup to $MAVEN_CONFIG
.
To create a pre-packaged repository, create a pom.xml
with the dependencies you need and use this in your Dockerfile
.
/usr/share/maven/ref/settings-docker.xml
is a settings file that changes the local repository to /usr/share/maven/ref/repository
,
but you can use your own settings file as long as it uses /usr/share/maven/ref/repository
as local repo.
COPY pom.xml /tmp/pom.xml
RUN mvn -B -f /tmp/pom.xml -s /usr/share/maven/ref/settings-docker.xml dependency:resolve
To add your custom settings.xml
file to the image use
COPY settings.xml /usr/share/maven/ref/
For an example, check the tests
dir
Maven needs the user home to download artifacts to, and if the user does not exist in the image an extra
user.home
Java property needs to be set.
For example, to run as user 1000
mounting the host' Maven repo
docker run -v ~/.m2:/var/maven/.m2 -ti --rm -u 1000 -e MAVEN_CONFIG=/var/maven/.m2 maven mvn -Duser.home=/var/maven archetype:generate
The maven
images come in many flavors, each designed for a specific use case.
This is the defacto image. If you are unsure about what your needs are, you probably want to use this one. It is designed to be used both as a throw away container (mount your source code and start the container to start your app), as well as the base to build other images off of.
Build with the usual
docker build -t maven .
Tests are written using bats under the tests
dir.
Use the env var TAG to choose what image to run tests against.
TAG=jdk-11 bats tests
or run all the tests with
for dir in $(/bin/ls -1 -d */ | grep -v tests); do TAG=$(basename $dir) bats tests; done
Bats can be easily installed with brew install bats
on OS X.
Note that you may first need to:
git submodule init
git submodule update
