Docker in Docker for bugzoo iteractions #5

I have a docker container that runs Bugzoo and I'm getting what seem to be socket issues - see below.
If I need to run bugzoo in another docker container, is there something I'm missing in my docker set up to enable this?
I'm running the encapsulating docker container with --privileged
The following trace happens after my script runs bugzoo source add <mysrc> <mysrc_path> in the docker container.

It looks like you've run into the problem of trying to interact with Docker whilst inside a Docker container. There are two common solutions to the problem. One solution is overkill and should be avoided at all costs (dind: Docker-in-Docker). The other, saner, solution is to mount the Docker socket (whose absence is causing the exception that you're seeing) into the BugZoo container via volume mounting:

$ docker run -v /var/run/docker.sock:/var/run/docker.sock --rm -it bugzoo

(Note: there are a couple of places where BugZoo interacts with Docker via the CLI rather than its HTTP interface. To avoid any issues, you'll probably want to install Docker inside the BugZoo container -- don't worry, that's not a Docker-in-Docker solution :slight_smile:.)
