Docker swarm can be on one server?

Hello. I am learning docker currently and I am asking if it is possible to run the whole docker swarm on one server? (I believe the minimum is two; for master and node) I have spare machine at home and I want to try this.

This is only temporary and then I will scale it after I do the testing.

Note: I will run this on Kubuntu 18.04.


Hi, yes this is possible.

The minimum requirements are if you are planning to use high availability.
So there is no issues on running a single node swarm
