Changing permissions for /var/lib/docker (self.docker)

submitted 1 year ago by aseriesoftubes to c/docker

4 comments fedilink hide all child comments

Is it a bad idea to recursively change the permissions for the /var/lib/docker directory? That directory is owned by root:root and the permissions are rwx--x---.

I'm hoping to be able to access my named volumes without using sudo so that I can easily back them up.

Only one way to find out :D

I mean in test, definitely in test not production I swear. I'm staying late working on unrelated projects.

Why are your named volumes related to /var/lib/docker at all?

If you want to back up the data, you just need to access wherever the host directory is.

/some/home/directory:/container/directory

You only need access to that host directory and back that up?

I think you’re thinking of bind mounts. Named volumes live in /var/lib/docker/volumes.

Gotcha - my mistake.
