Swarm, yesterday
For the very first example, we'll run the easiest possible configuration of a Swarm v1 cluster locally to get a taste of how "old" Swarms worked (and still works). This tiny cluster will have the following features:
- Made of four nodes of 1CPU, 1GB of memory each, it will consist of an infrastructure of four CPUs and 4GB of memory available in total
- Each node will run on VirtualBox
- Each node is connected to each other on the local VirtualBox network
- No discovery service is involved: a static

Our cluster will look similar to the following diagram. Four Engines will be connected to each other through port 3376 in a mesh. Beyond the Docker engine, ...
