containership has two modes it can run in: leader & follower
You'll need at least one leader host for the cluster to function, and a minimum of 3 for true high availability.
Follower hosts are where your containers will actually be placed and will run. The specs on these servers should be great enough to fit all of the containers/applications you plan to run.
For a small test deployment with under 10 followers, you can get away with running your leaders on the smallest DigitalOcean droplets without any problems. Once you get up into larger number of follower hosts the hardware requirements of the leaders will change, but not significantly.
