          balance: roundrobin
          servers:
            - type: AGENT_IP
              framework:
                value: marathon
              task:
                value: "^myapp-prod-v[0-9]+\\.my-dcos-account$"
                match: REGEX
              port:
                name: web
- Launch the configuration with the following command:
 
dcos edgelb config config.yaml
Edge-LB will round-robin over the instances in the server groups of the myapp-prod cluster.
