Running Docker w/bind mounts inside the runner

[glenn-lytx]

Howdy,

I can't seem to do a bind mount a directory inside the runner itself. Use case would be to use a golang container, bind mount the source repo, and then build the artifact. Example:

docker run -v ~/bin:/root/bin:rw -it alpine sh

Works fine on a straight Docker host, and I'll see files under /root/bin inside the container. But when I run the same command on the runner I see nada.

I'm assuming this has something to do w/running Docker against the socket inside of Docker. Any ideas?

After some research it's the dind sidecar. To solve basically just share anything in /runner and it works.
