    iface eth0 inet static
    address 172.16.197.11
    netmask 255.255.255.0
    gateway 172.16.197.254
    EOT
  
    service networking restart
    service docker restart

  docker -H=tcp://172.16.197.11:2375 run -d swarm join --advertise=172.16.197.11:2375 consul://172.16.197.10:8500

daemon.json

{
