       -o com.docker.network.bridge.name=docker_gwbridge \
     docker_gwbridge

--- In manager node
$ sudo docker swarm init --advertise-addr MANGER_IP_ADDRESS

--- In worker node
$ sudo docker swarm join --token TOKEN_KEY MANGER_IP_ADDRESS:2377

--- Verify
$ sudo docker node ls

--- Set overlay network
$ sudo docker network \
       create \
       --attachable \
       --driver=overlay \
