I had a really high load on my Mac Mini Server. As it is a Late 2014 with only two CPU-Cores, everything hurts which makes the Server slow.

Image Description

What is Docker Swarm Mode?

A swarm is a cluster of Docker engines, or nodes, where you deploy services.

What is a 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'.
