Many applications may require a connection to an AMQP protocol message broker. score-compose comes with a built-in provider for RabbitMQ using the public docker image.
When this provider is used, it will generate a single RabbitMQ instance with a v-host per AMQP resource definition.
resources:
bus:
type: amqp
The provided outputs are host, port, vhost, username, and password and these can be assembled together into a
URI like amqp://${resources.bus.username}:${resources.bus.password}@${resources.bus.host}:${resources.bus.port}/${resources.bus.vhost}.
The generated user has administrator permissions on the vhost.
For more complicated configuration, it is recommended to copy the default rabbitmq provisioner to your own provisioners file and modify the configuration.
By tagging your amqp resources with the publish-port annotations you can publish the ports on localhost:
resources:
bus:
type: amqp
metadata:
annotations:
"compose.score.dev/publish-port": "5672"
"compose.score.dev/publish-management-port": "15672"While you can add this to your main Score file, it's a good idea to apply this as an --overrides-file.
The default user with username guest, password guest will be available. This is very useful for debugging applications.
