Quickstart Docker Swarm
What is Docker Swarm Mode?
A swarm is a cluster of Docker engines, or nodes, where you deploy services.
What is a node?
A node is an instance of the Docker engine participating in the swarm. You can also think of this as a Docker node.
You can run one or more nodes on a single physical computer or cloud server, but production swarm deployments typically include Docker nodes distributed across multiple physical and cloud machines.
That means I can create a Docker Swarm with my '6-Node Cluster of Raspberries'.
