Three, docker Swarm cluster of commonly used commands
[root @ docker01 ~] # information docker node ls # View cluster (can only be viewed on the manager role of the host)
[root @ docker01 ~] # Docker the Swarm the Join-token worker # If the latter need to join the worker side, you can do this command to view the token (ie command to be executed when added)
[root @ docker01 ~] # Docker the Join the Swarm # above-token manager, manager to join the end, you can execute this command to view the token.
[root @ docker01 ~] # docker service scale web05 = dynamic expansion 6 # container and volume reduction
[root @ docker01 ~] # docker service ps web01 # container runs view created which node
[root @ docker01 ~] # docker service ls # View created service
# will docker03 out of this cluster
[root @ docker03 ~] # docker swarm leave # docker03 out of this cluster
[root @ docker01 ~] # docker node rm docker03 # then removed docker03 on the role of manager server
[ root @ docker01 ~] # docker node promote docker02 # docker02 will upgrade from worker to manager.
# After the upgrade docker02 status to Reachable
[root @ docker01 ~] # Docker --availability Drain docker01 the Node Update
# do not run after setting the host docker01 container, but the container has been running and does not stop
