This project sets up a Docker Swarm Mode cluster. It will create X managers (defaults to 1) and Y workers (defaults to 1).


Just start your cluster with vagrant up to kick in with the default setup. To modify the number of managers and workers edit the Vagrant file and modify the appropriate constants in the beginning of the file:


Adding Managers and Workers

If additional managers and/or workers need to be added to an existing swarm just update the same variables as shown above and run vagrant up again. The new nodes will be added to the swarm.


To start from scratch make sure to remove the 'swarm-token' folder which will be created by the first manager started. Something like the following would make sense:

vagrant destroy --force
rm -rf swarm-token

This folder is used to store the tokens (managers and workers) for joining the swarm.
