### Run services on predefined networks
You can create services on the predefined docker networks `bridge` and `host`.
```bash
$ docker service create --name my-service \
--network host \
--replicas 2 \
busybox top
```
### Swarm networks with local scope drivers
You can create a swarm network with local scope network drivers. You do so
by promoting the network scope to `swarm` during the creation of the network.
You will then be able to use this network when creating services.
```bash
$ docker network create -d bridge \
--scope swarm \
--attachable \
swarm-network
```
For network drivers which provide connectivity across hosts (ex. macvlan), if
node specific configurations are needed in order to plumb the network on each
host, you will supply that configuration via a configuration only network.
When you create the swarm scoped network, you will then specify the name of the
network which contains the configuration.
```bash
node1$ docker network create --config-only --subnet 192.168.100.0/24 --gateway 192.168.100.115 mv-config
node2$ docker network create --config-only --subnet 192.168.200.0/24 --gateway 192.168.200.202 mv-config
node1$ docker network create -d macvlan --scope swarm --config-from mv-config --attachable swarm-network
```
