Mount host directory into a docker container run from within docker container

Question

I have some unusual case. Namely, I run a docker container, let us call it container1 and I mount docker socket from my host into it: -v /var/run/docker.sock:/var/run/docker.sock.

Then, from within a container1 I want to run another container, let us call it container2. As I have a host's docker socket mounted, I can do that with ease.

Now the question: how can I mount a directory from my host inside container2?

Since you mounted the docker socket, what you do wiht docker in container1 is just like what you do on the host. If you need to mount a directory from host to container2, just use -v /path/on/host:/target. Because it's the docker running on the host, that's going to interpret /path/on/host

OMG. I have spent a couple of hours totally confusing what a host is... Sorry.

Critically, the docker run -v option or API equivalent always takes physical-host paths: you cannot bind-mount a directory from container1 into container2.
