Docker Volume Basics

Volumes are the preferred method of maintaining persistent data in Docker. In this lesson, we will begin learning how to use the volume subcommand to list, create, and remove volumes.

Step 1: List all Docker volume commands:

docker volume --help

• create: Create a volume.

• inspect: Display detailed information on one or more volumes.

• ls: List volumes.

• prune: Remove all unused local volumes.

• rm: Remove one or more volumes.

Step 2: List all volumes on a host:

docker volume ls

Step 3: Create two new volumes:

docker volume create test-volume1

docker volume create test-volume2

Step 4: Get the flags available when creating a volume:

docker volume create -h

Step 5: Inspecting a volume:

docker volume inspect test-volume1

Step 6: Deleting a volume:

docker volume rm test-volume1

Removing all unused volumes:

docker volume prune
