You can create a Docker volume using the docker volume create command, or automatically by mounting a volume when running a container with the -v or --mount flag.
Docker provides multiple ways to create volumes depending on your workflow and whether you need to manage the volume separately from containers. You can explicitly create a named volume before using it, or let Docker create a volume automatically when you first reference it in a container run command. Both approaches result in volumes stored in Docker's managed storage area (/var/lib/docker/volumes/ on Linux).
Named volumes (
docker volume create) give you explicit control over volume names and options, making them easier to reference later in multiple containers .Anonymous volumes (just
-v /container/path) create volumes with random names, useful for temporary data where you don't need to reference the volume by name .Automatic named volumes (mount a non-existent volume name) create the volume if it doesn't exist when you first run a container, combining convenience with identifiable names .
After creation, volumes appear in docker volume ls and can be managed independently of containers. They persist even after all containers using them are removed, until you explicitly delete them with docker volume rm or docker volume prune. You can also back up, restore, and migrate volumes using temporary containers that mount both the volume and a host directory for the backup archive.
