description: >
|
|
This template will boot a Docker swarm cluster. A swarm cluster is made up
|
|
of several master nodes, and N agent nodes. Every node in the cluster,
|
|
including the master, is running a Docker daemon and a swarm agent
|
|
advertising it to the cluster. The master is running an addition swarm
|
|
master container listening on port 2376. By default, the cluster is made
|
|
up of one master node and one agent node.
