More Information

Private Network

coreos-cluster-cli now supports adding a --private-network [guid] to each machine on the cluster, and will bind etcd to this private network. This is only available for performance type clusters. To get the guid of a private network in the desired region, please access the rackspace control panel.

Adding to an existing cluster

You can now provide the --discovery-service-url [url] of an existing cluster. Doing so will add --num-nodes to the current cluster, instead of registering a new cluster.

Cloud Monitoring

If you provide --monitoring-token [token] to your call, all of the created nodes will be registered with Cloud Monitoring. You can get an existing Cloud Monitoring token via the API: http://docs.rackspace.com/cm/api/v1.0/cm-devguide/content/service-agent-tokens.html#service-agent-token-list
