# 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.
|
||
|
|
|
||
|
|
```bash
|
||
|
|
$ 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.
|
||
|
|
|
||
|
|
```bash
|
||
|
|
$ 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.
|
||
|
|
|
||
|
|
```bash
|
||
|
|
$ docker daemon -H=<node_ip:2376> --discovery-address=<node_ip:2376> --discovery-backend zk://<zk_addr1>,<zk_addr2>>/<path>
|
||
|
|
```
