# Apache ActiveMQ Artemis Container Image
2020-07-17 15:47:47 +02:00

This is a container Image of Apache ActiveMQ Artemis that can be used inside Kubernetes.
# 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 the 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.
