This leverages recent additions to libkv enabling client
authentication via TLS so the discovery back-end can be locked
down with mutual TLS. Example usage:
docker daemon [other args] \
--cluster-advertise 192.168.122.168:2376 \
--cluster-store etcd://192.168.122.168:2379 \
--cluster-store-opt kv.cacertfile=/path/to/ca.pem \
--cluster-store-opt kv.certfile=/path/to/cert.pem \
--cluster-store-opt kv.keyfile=/path/to/key.pem

Discovery
Docker comes with multiple Discovery backends.
Backends
Using etcd
Point your Docker Engine instances to a common etcd instance. You can specify
the address Docker uses to advertise the node using the --discovery-address
flag.
$ docker daemon -H=<node_ip:2376> --discovery-address=<node_ip:2376> --discovery-backend etcd://<etcd_ip>/<path>
Using consul
Point your Docker Engine instances to a common Consul instance. You can specify
the address Docker uses to advertise the node using the --discovery-address
flag.
$ docker daemon -H=<node_ip:2376> --discovery-address=<node_ip:2376> --discovery-backend consul://<consul_ip>/<path>
Using zookeeper
Point your Docker Engine instances to a common Zookeeper instance. You can specify
the address Docker uses to advertise the node using the --discovery-address
flag.
$ docker daemon -H=<node_ip:2376> --discovery-address=<node_ip:2376> --discovery-backend zk://<zk_addr1>,<zk_addr2>>/<path>
