Docker Image Example

This is an example on how you could create your own Docker Image For Apache ActiveMQ Artemis based on CentOS or Debian (JDK 8) or AdoptOpen JDK 11 (Ubuntu).

Preparing

Use the script ./prepare-docker.sh as it will copy the docker files under the binary distribution.

Below is shown the command to prepare the build of the Docker Image starting from the local distribution (from the source codes of ActiveMQ Artemis)

# Prepare for build the Docker Image from the local distribution. Replace the 
# {local-distribution-directory} with your directory.
$ ./prepare-docker.sh --from-local-dist --local-dist-path {local-distribution-directory}

The output of the previous command is shown below.

$ ./prepare-docker.sh --from-local-dist --local-dist-path ../artemis-distribution/target/apache-artemis-2.17.0-SNAPSHOT-bin/apache-artemis-2.17.0-SNAPSHOT

Using Artemis dist: ../artemis-distribution/target/apache-artemis-2.17.0-SNAPSHOT-bin/apache-artemis-2.17.0-SNAPSHOT
Clean up the ../artemis-distribution/target/apache-artemis-2.17.0-SNAPSHOT-bin/apache-artemis-2.17.0-SNAPSHOT/docker directory
Docker file support files at : ../artemis-distribution/target/apache-artemis-2.17.0-SNAPSHOT-bin/apache-artemis-2.17.0-SNAPSHOT/docker
../artemis-distribution/target/apache-artemis-2.17.0-SNAPSHOT-bin/apache-artemis-2.17.0-SNAPSHOT/docker
├── Dockerfile-eclipse-temurin-11
├── Dockerfile-centos
├── Dockerfile-debian
└── docker-run.sh

0 directories, 4 files

Well done! Now you can continue with the Docker image build.
Building the Docker Image:
  Go to ../artemis-distribution/target/apache-artemis-2.17.0-SNAPSHOT-bin/apache-artemis-2.17.0-SNAPSHOT where you prepared the binary with Docker files.

  # Go to ../artemis-distribution/target/apache-artemis-2.17.0-SNAPSHOT-bin/apache-artemis-2.17.0-SNAPSHOT
  $ cd ../artemis-distribution/target/apache-artemis-2.17.0-SNAPSHOT-bin/apache-artemis-2.17.0-SNAPSHOT

  # For Debian
  $ docker build -f ./docker/Dockerfile-debian -t artemis-debian .

  # For CentOS
  $ docker build -f ./docker/Dockerfile-centos -t artemis-centos .

  # For AdoptOpen JDK 11
  $ docker build -f ./docker/Dockerfile-eclipse-temurin-11 -t artemis-eclipse-temurin-11 .

Note: -t artemis-debian, -t artemis-centos and artemis-eclipse-temurin-11 are just
tag names for the purpose of this guide

For more info read the readme.md

The command to prepare the build of the Docker Image starting from the official release of ActiveMQ Artemis is shown below

# Prepare for build the Docker Image from the release version. Replace the
# {release-version} with the version that you want 
$ ./prepare-docker.sh --from-release --artemis-version {release-version}

The output of the previous command is shown below.

$ ./prepare-docker.sh --from-release --artemis-version 2.16.0

Building

Go to $ARTEMIS_DIST where you prepared the binary with Docker files.

For Debian

From within the $ARTEMIS_DIST folder:

$ docker build -f ./docker/Dockerfile-debian -t artemis-debian .

For CentOS

From within the $ARTEMIS_DIST folder:

$ docker build -f ./docker/Dockerfile-centos -t artemis-centos .

For AdoptOpen JDK 11

From within the $ARTEMIS_DIST folder:

$ docker build -f ./docker/Dockerfile-eclipse-temurin-11 -t artemis-eclipse-temurin-11 .

For AdoptOpen JDK 11 (Build for linux ARMv7/ARM64)

$ docker buildx build --platform linux/arm64,linux/arm/v7 --push -t {your-repository}/apache-artemis:2.17.0-SNAPSHOT -f ./docker/Dockerfile-eclipse-temurin-11 .

Note: -t artemis-debian,-t artemis-centos,artemis-eclipse-temurin-11 are just tag names for the purpose of this guide

Environment Variables

Environment variables determine the options sent to artemis create on first execution of the Docker container. The available options are:

ARTEMIS_USER

The administrator username. The default is artemis.

ARTEMIS_PASSWORD

The administrator password. The default is artemis.

ANONYMOUS_LOGIN

Set to true to allow anonymous logins. The default is false.

EXTRA_ARGS

Additional arguments sent to the artemis create command. The default is --http-host 0.0.0.0 --relax-jolokia. Setting this value will override the default. See the documentation on artemis create for available options.

Final broker creation command:

The combination of the above environment variables results in the docker-run.sh script calling the following command to create the broker instance the first time the Docker container runs:

${ARTEMIS_HOME}/bin/artemis create --user ${ARTEMIS_USER} --password ${ARTEMIS_PASSWORD} --silent ${LOGIN_OPTION} ${EXTRA_ARGS}

Note: LOGIN_OPTION is either --allow-anonymous or --require-login depending on the value of ANONYMOUS_LOGIN.

Mapping point

  • /var/lib/artemis-instance

It's possible to map a folder as the instance broker. This will hold the configuration and the data of the running broker. This is useful for when you want the data persisted outside of a container.

Lifecycle of the execution

A broker instance will be created during the execution of the instance. If you pass a mapped folder for /var/lib/artemis-instance an image will be created or reused depending on the contents of the folder.

Running a CentOS image

The image just created in the previous step allows both stateless or stateful runs. The stateless run is achieved by:

$ docker run --rm -it -p 61616:61616 -p 8161:8161 artemis-centos

The image will also support mapped folders and mapped ports. To run the image with the instance persisted on the host:

docker run -it -p 61616:61616 -p 8161:8161 -v <broker folder on host>:/var/lib/artemis-instance artemis-centos

where <broker folder on host> is a folder where the broker instance is supposed to be saved and reused on each run.
