Place swarm worker nodes in maintenance mode

How to place swarm worker nodes in maintenance mode for patching etc

vagrant@swarm1010:~$ docker node ls

Show service  

docker service ls

 docker service ps east-webservers –filter DESIRED-STATE=running

Placing a worker node in DRAIN will shut all the container in that node and move it to peer nodes

vagrant@swarm1010:~$ docker node update swarm1012 –availability drain 

docker service ps east-webservers –filter DESIRED-STATE=running

There are no containers running on swarm1012
