Dev Services for AMQP

Dev Services for AMQP automatically starts an AMQP 1.0 broker in dev mode and when running tests. So, you don’t have to start a broker manually. The application is configured automatically.

Enabling / Disabling Dev Services for AMQP

Dev Services for AMQP is automatically enabled unless:

  • quarkus.amqp.devservices.enabled is set to false

  • the amqp-host or amqp-port is configured

  • all the Reactive Messaging AMQP channels have the host or port attributes set

Dev Services for AMQP relies on Docker to start the broker. If your environment does not support Docker, you will need to start the broker manually, or connect to an already running broker. You can configure the broker access using the amqp-host, amqp-port, amqp-user and amqp-password properties.

Shared broker

Most of the time you need to share the broker between applications. Dev Services for AMQP implements a service discovery mechanism for your multiple Quarkus applications running in dev mode to share a single broker.

Note
 Dev Services for AMQP starts the container with the quarkus-dev-service-amqp label which is used to identify the container.

If you need multiple (shared) brokers, you can configure the quarkus.amqp.devservices.service-name attribute and indicate the broker name. It looks for a container with the same value, or starts a new one if none can be found. The default service name is amqp.

Sharing is enabled by default in dev mode, but disabled in test mode. You can disable the sharing with quarkus.amqp.devservices.shared=false.

Setting the port

By default, Dev Services for AMQP picks a random port and configures the application. You can set the port by configuring the quarkus.amqp.devservices.port property.

Configuring the image

Dev Services for AMQP uses activemq-artemis-broker images. You can configure the image and version using the quarkus.amqp.devservices.image-name property:

quarkus.amqp.devservices.image-name=quay.io/artemiscloud/activemq-artemis-broker:latest
