Etcd proxies are deployed on each node in the `k8s-cluster` group. A proxy is |
|
|
|
a separate etcd process. It has a `localhost:2379` frontend and all of the etcd |
|
|
|
cluster members as backends. Note that the `access_ip` is used as the backend |
|
|
|
IP, if specified. Frontend endpoints cannot be accessed externally as they are |
|
|
|
bound to a localhost only. |

The `etcd_access_endpoint` fact provides an access pattern for clients. And the |

flannel networking plugin always uses a single `--etcd-server` endpoint! |
