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 --cluster-advertise flag.

$ dockerd -H=<node_ip:2376> --cluster-advertise=<node_ip:2376> --cluster-store etcd://<etcd_ip1>,<etcd_ip2>/<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 --cluster-advertise flag.

$ dockerd -H=<node_ip:2376> --cluster-advertise=<node_ip:2376> --cluster-store 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 --cluster-advertise flag.

$ dockerd -H=<node_ip:2376> --cluster-advertise=<node_ip:2376> --cluster-store zk://<zk_addr1>,<zk_addr2>/<path>
