Backing Up and Restoring a Docker Swarm
For the last six months, the Acme Anvil Corporation has been migrating some of their bare metal infrastructure to Docker containers. A schism has developed between the members of your team on whether to use Docker Swarm or Kubernetes. To settle the dispute, your manager has decided to create a series of challenges. You have been tasked with creating a demo on how to back up and restore a Docker swarm. You are to set up a Docker swarm with 3 nodes, scale the backup service up to 3 nodes, and back up your master node and restore it to a backup instance.
