In this chapter, we will learn the secrets of Docker volumes. We will learn how to use folders on your workstation inside of your Docker containers, and we will learn how to create and use persistent volumes, allowing multiple containers to share data. We will learn how to clean up after unused volumes. And, to round out this chapter, we will learn how to create data-volume containers to become the source of volumes for other containers.

In this chapter, we will cover the following topics:
