Chapter 7. Connecting to external services
You can connect a router to an external service such as a message broker. The services may be running in the same OpenShift cluster as the router network, or running outside of OpenShift.
Prerequisites
- You must have access to a message broker.
Procedure
This procedure describes how to connect a router to a broker and configure a link route to connect messaging clients to it.
Start editing the
InterconnectCustom Resource YAML file that describes the router deployment that you want to connect to a broker.$ oc edit -f router-mesh.yaml
In the
specsection, configure the connection and link route.Sample
router-mesh.yamlfileapiVersion: interconnectedcloud.github.io/v1alpha1 kind: Interconnect metadata: name: router-mesh spec: ... connectors: 1 - name: my-broker host: broker port: 5672 routeContainer: true linkRoutes: 2 - prefix: q1 direction: in connection: my-broker - prefix: q1 direction: out connection: my-broker

- The connection to be used to connect this router to the message broker. The Operator will configure this connection from every router defined in this router deployment to the broker. If you only want a single connection between the router network and the broker, then configure a
listenerinstead of a connector and have the broker establish the connection. - 2
- The link route configuration. It defines the incoming and outgoing links and connection to be used to connect messaging applications to the message broker.
Verify that the router has established the link route to the message broker.
