rovigattibetacom/java21-artemis-mq repository overview

⁠Java 21 and Artemis Mq

An Alpine based image that relies on Java 21 and Artemis Mq to provide a simple and plain message broker

⁠Usage

Once the image is pulled from the Docker Hub, it's possible to launch it with Dockerfile or with Docker Compose by the setup of the entrypoint.

⁠Broker implementation

This command defines the message broker implementation
"/home/artemio/apache-artemis-2.53.0/bin/artemis" create /home/artemio/broker --name brokerArtemio --user admin --password <admin Password> --role admins --silent --require-login --http-host 0.0.0.0 --no-autocreate --verbose;

--no-autocreate doesn't allow to create new queue/topic forcing to use the ones defined in the broker.xml files of the broker implementation.

⁠Broker implementation abstract setup

This command
mv /home/artemio/supporto/broker.xml /home/artemio/broker/etc ;
overrides the broker.xml files of the broker implementation following the abstract setup I created this image for
-coda01 anycast queue creation
-topicArtemio multicast topic creation
-allowing guests type user to read/write queue (anycast) and topic (multicast)

⁠Custom queues and topics

To define custom queues or topics refers to this options of the broker instance creation (section above)
--queues <queue name> --addresses <topic name>

⁠Guests type user definition and starting Artemis

This command will define a new guests type user then starting artemis "/home/artemio/broker/bin/artemis-service" start; "/home/artemio/broker/bin/artemis" user add --user-command-user <guests user name> --user-command-password <guests user password> --role guests --user admin --password <admin Password>; "/home/artemio/broker/bin/artemis-service" stop; /home/artemio/broker/bin/artemis" run;

⁠Out of the box homage

I chose artemio as linux user name also to pay homage to the main character of "Il Ragazzo di Campagna" italian milestone movie called Artemio
