Storage volumes provide a powerful and flexible way to add persistent storage to your containers, but what if you need to share storage volumes across multiple Docker hosts, such as a Swarm cluster? In this lab, you will have the opportunity to work with a simple method of creating shared volumes usable across multiple swarm nodes using the sshfs volume driver.

Docker swarm is an orchestration tool, similar to Kubernetes, but simpler to set up and manage. It doesn't come with a shared storage solution out of the box, so that is something you need to take care for yourself.
