Persistent storage with docker

dwtbf

How do I do? I setup ghost blog, but read there's a way to persist storage in shared folder, but I don't get how it's done, could someone explain like I'm 5?

You can either mount a local directory or let docker create a new volume, which is like a directory but managed by docker.

docker run -v /local/path:/container/path imagename

This will mount the /local/path at /container/path.

docker run -v foo:/container/path imagename

This will create a new volume named foo and mount it at /container/path.

All of this is documented at https://docs.docker.com/engine/tutorials/dockervolumes/

If you're using the offical ghost image, the correct path to mount in the container would be /var/lib/ghost.
