Are you tired of dealing with the frustrating issue of your local broker.xml file being modified by the ActiveMQ Artemis container? Well, worry no more! In this comprehensive guide, we’ll walk you through the process of mounting your local broker.xml file to an ActiveMQ Artemis container, ensuring that your local file remains unchanged.
Why Mount a Local broker.xml File?
Before we dive into the solution, let’s understand why you would want to mount a local broker.xml file to an ActiveMQ Artemis container. Here are a few reasons:
- Customization: By mounting a local
broker.xmlfile, you can customize the configuration of your ActiveMQ Artemis broker to suit your specific needs. - Development and Testing: Mounting a local
broker.xmlfile allows you to test and develop your application with a specific configuration, which can then be easily swapped out for a production-ready configuration. - Version Control: By keeping your
broker.xmlfile under version control, you can track changes and collaborate with others on your team more effectively.
Docker and Volumes: A Quick Primer
Before we continue, let’s take a brief look at Docker and volumes. Docker is a containerization platform that allows you to package, ship, and run applications in containers. Containers are lightweight and portable, making them ideal for development and deployment. Volumes, on the other hand, are directories that are shared between the host machine and the container. This allows you to persist data even if the container is deleted or recreated.
What is a Container Volume?
A container volume is a directory that is shared between the host machine and the container. When you mount a volume, you’re essentially creating a shared directory that can be accessed from both the host machine and the container. This allows you to persist data, such as configuration files, even if the container is deleted or recreated.
Mounting a Local broker.xml File to an ActiveMQ Artemis Container
Now that we’ve covered the basics, let’s get started with mounting a local broker.xml file to an ActiveMQ Artemis container.
Step 1: Create a Local broker.xml File
Create a new file named broker.xml in a directory of your choice (e.g., /path/to/config). Populate the file with your desired configuration settings.
<configuration xmlns="urn:activemq:artemis">
<core>
<queues>
<queue name="myQueue" />
</queues>
</core>
</configuration>
Step 2: Create a Docker Compose File
Create a new file named docker-compose.yml in a directory of your choice (e.g., /path/to/project). Populate the file with the following contents:
version: '3'
services:
artemis:
image: vromero/activemq-artemis:2.17.0
volumes:
- ./config:/opt/activemq-artemis/config:ro
ports:
- "8161:8161"
- "61616:61616"
In this example, we’re using the vromero/activemq-artemis:2.17.0 image and mapping the ./config directory on the host machine to the /opt/activemq-artemis/config directory inside the container. The :ro flag specifies that the volume should be mounted as read-only, ensuring that the container cannot modify the local file.
Step 3: Start the Container
Open a terminal and navigate to the directory where your docker-compose.yml file is located. Run the following command to start the container:
docker-compose up -d
This command will start the container in detached mode, which means it will run in the background.
Step 4: Verify the Configuration
Open a web browser and navigate to http://localhost:8161/console. You should see the ActiveMQ Artemis console. Click on the “Browse” tab and select the “myQueue” queue that we defined in our broker.xml file.
Verify that the queue has been created successfully by checking the “Messages” tab.
Troubleshooting Tips
If you’re experiencing issues with your local broker.xml file being modified by the container, here are a few troubleshooting tips to keep in mind:
- Check the volume permissions: Make sure that the volume is mounted with the correct permissions. In our example, we used the
:roflag to ensure that the volume is mounted as read-only. - Verify the container logs: Check the container logs for any errors or warnings related to the
broker.xmlfile. You can do this by running the commanddocker-compose logs -f artemis. - Check the file permissions: Make sure that the local
broker.xmlfile has the correct permissions. You can check the file permissions by running the commandls -l /path/to/config/broker.xml.
Conclusion
In this article, we’ve covered the steps to mount a local broker.xml file to an ActiveMQ Artemis container, ensuring that your local file remains unchanged. By following these steps and troubleshooting tips, you should now be able to customize and persist your ActiveMQ Artemis configuration with ease.
Remember to keep your broker.xml file under version control, and don’t hesitate to reach out if you have any further questions or concerns.

Frequently Asked Question
Get the answers to your burning questions about mounting local broker.xml to ActiveMQ Artemis container!
Why does the ActiveMQ Artemis container change my local broker.xml file?
By default, the ActiveMQ Artemis container will overwrite your local broker.xml file with its own configuration. This is because the container is designed to deploy a self-contained broker configuration. To prevent this, you can use a volume mount to persist your local configuration.
How do I mount my local broker.xml file to the ActiveMQ Artemis container?
You can mount your local broker.xml file to the container using a Docker volume mount. For example, you can use the following command: docker run -v /path/to/local/broker.xml:/etc/artemis/broker.xml -p 61616:61616 activemq/artemis. This will mount your local broker.xml file to the container’s configuration directory.
What happens if I don’t mount my local broker.xml file to the container?
If you don’t mount your local broker.xml file to the container, the container will use its own default configuration. This means that any customizations you’ve made to your local broker.xml file will be lost when the container starts. Additionally, any changes you make to the container’s configuration will not be persisted across container restarts.
Can I use a different configuration file name instead of broker.xml?
Yes, you can use a different configuration file name instead of broker.xml. However, you’ll need to specify the configuration file name using the --broker-config option when starting the container. For example: docker run -v /path/to/local/config.xml:/etc/artemis/config.xml -p 61616:61616 activemq/artemis --broker-config /etc/artemis/config.xml.
What are some common issues that can occur when mounting a local broker.xml file to the ActiveMQ Artemis container?
Some common issues that can occur when mounting a local broker.xml file to the ActiveMQ Artemis container include incorrect file permissions, incorrect file paths, and configuration file format errors. Additionally, if the container is not able to read the mounted file, it may fall back to its own default configuration.
