An example showing three inter-connected deployments in separate namespaces. This could easily be adapted to work with three separate clusters, as the inter-router connection is done over external routes.

Startup cluster, e.g.:

  oc cluster up

Create three projects called cluster-a, cluster-b and cluster-local. For each project:

• create a secret called qdr-internal-cert containing the internal tls certificates and key to use between routers

• create a configmap called qdr-config containing the router config to use (i.e. qdrouterd.conf.a, qdrouterd.conf.b or qdrouterd.conf.local as appropriate)

• create deployment, secret and route (using qdr.yaml.a, qdr.yaml.b or qdr.yaml.local as appropriate)

This can all be done by running the setup script. NOTE: you will have to edit the yaml files to replace the hostname with something suitable for your environment.

To verify:

  qdstat -b $(oc get service messaging -n cluster-a -o jsonpath='{.spec.clusterIP}') -n
  qdstat -b $(oc get service messaging -n cluster-b -o jsonpath='{.spec.clusterIP}') -n
  qdstat -b $(oc get service messaging -n cluster-local -o jsonpath='{.spec.clusterIP}') -n

The certificates can be generated using the generate_certs script, though the subject should be changed to match the hostname used for the routes.
