Federation in ArtemisCloud

[beaver71]

What is the simplest way to configure federation (see https://activemq.apache.org/components/artemis/documentation/latest/federation-address.html#address-federation) between an ArtemisCloud instance and another external Artemis?
This is a sample configuration for Artemis standard setup (non ArtemisCloud):

	<connectors>
	   <connector name="artemis-external">tcp://<external-address>:61616</connector>
	</connectors>

	<federations>
	   <federation name="artemis-fed" user="***" password="***">
		  <upstream name="artemis-external-up">
			  <static-connectors>
				 <connector-ref>artemis-external</connector-ref>
			  </static-connectors>
			  <policy ref="address-policy"/>
		  </upstream>
		  <address-policy name="address-policy">
			 <include address-match="test" />
		  </address-policy>
	   </federation>
	</federations>

@beaver71 are the ArtemisCloud instance and another external Artemis in the same Kubernetes cluster? If not is the ArtemisCloud instance able to reach the external Artemis?

[beaver71]

No, the artemis external is not in the same k8s cluster but it is reachable by the ArtemisCloud instance

The simplest way to configure federation is by using broker properties, i.e.

apiVersion: broker.amq.io/v1beta1
kind: ActiveMQArtemis
metadata:
  name: artemis-broker
spec:
  brokerProperties:
    - connectorConfigurations.artemis-external.factoryClassName=org.apache.activemq.artemis.core.remoting.impl.netty.NettyConnectorFactory
    - connectorConfigurations.artemis-external.params.host=<external-address>
    - connectorConfigurations.artemis-external.params.port=61616
    - federationConfigurations.artemis-fed.credentials.user=***
    - federationConfigurations.artemis-fed.credentials.password=***
    - federationConfigurations.artemis-fed.addressPolicies.address-policy.includes.just-b.addressMatch=test
    - federationConfigurations.artemis-fed.upstreamConfigurations.artemis-external-up.connectionConfiguration.staticConnectors=artemis-external
    - federationConfigurations.artemis-fed.upstreamConfigurations.artemis-external-up.policyRefs=address-policy

Thanks. I find the configuration via properties very poorly documented and difficult to understand.
For example, where is the connector name "artemis-external" specified?
How can I understand how to configure address policies via broker properties?

[brusdev]

I have just fixed the name of the connector in my example.

The configuration properties are low level, lower level than xml, however it is very powerful; any accessible attribute of the internal org.apache.activemq.artemis.core.config.impl.ConfigurationImpl objects can be modified, for further details see https://activemq.apache.org/components/artemis/documentation/latest/configuration-index.html#broker-properties
