docker swarm

A container orchestration tool. More information: https://docs.docker.com/engine/swarm/.

• Initialize a swarm cluster:
  docker swarm init
• Display the token to join a manager or a worker:
  docker swarm join-token {{worker|manager}}
• Join a new node to the cluster:
  docker swarm join --token {{token}} {{manager_node_url:2377}}
• Remove a worker from the swarm (run inside the worker node):
  docker swarm leave
• Display the current CA certificate in PEM format:
  docker swarm ca
• Rotate the current CA certificate and display the new certificate:
  docker swarm ca --rotate
• Change the valid period for node certificates:
  docker swarm update --cert-expiry {{hours}}h{{minutes}}m{{seconds}}s
