How do I delete a Docker Volume?

Use `docker volume rm `. You can also run `docker volume prune` to permanently delete ALL volumes that are not currently attached to a running container. Be extremely careful with prune, as it deletes data.

Can two containers share the same Volume?

Absolutely. You can run two separate containers and pass `-v my-data:/data` to both of them. They will both read and write to the exact same shared folder. This is useful for worker containers processing files uploaded by a web container.

What is a 'tmpfs' mount?

It's a third, rarer type of mount. A `tmpfs` mount stores data in the Host's RAM, not the hard drive. It is blazing fast but completely disappears the moment the container stops. It is useful for highly secure cryptographic keys that you never want written to disk.
