# 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.
|
|
|
|
```bash
|
|
$ 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.
|
|
|
|
```bash
|
|
$ 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.
|
|
|
|
```bash
|
|
$ dockerd -H=<node_ip:2376> --cluster-advertise=<node_ip:2376> --cluster-store zk://<zk_addr1>,<zk_addr2>/<path>
|
|
```
