Edge-LB

Edge-LB is the load balancer that comes with DC/OS Enterprise. See the DC/OS Enterprise documentation on how to install Edge-LB.

Create a config.yaml file with the following Edge-LB configuration. This configuration works with the rolling blue-green sample.

---
pools:
  - name: myapp-prod-pool
    count: 1
    haproxy:
      frontends:
        - bindPort: 80
          protocol: HTTP
          linkBackend:
            defaultBackend: myapp-prod
      backends:
        - name: myapp-prod
          protocol: HTTP
          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 configure the instances in the server groups of the myapp-prod cluster in a round-robin sequence.
