问题
I'm building a test project that requires a module outside of the project directory. The project folder is in docker, and I would like to bind that module directory to the docker container of my project. Is it even possible to do it? Or am I asking the wrong question? By the way, I'm still new to docker so I'm just trying things out.

My understand is, you need mount the host folder to the container. So try this:
docker run -v /host/project_folder:/container/project -t avian/project_image bash
explanation
-v- --volume=[] Bind mount a volume/host/project_folder- host server's folder/container/project- container's folder
Update:
The latest docker version (v1.9.1) support a new command volume. So you should be easier to manage volume in docker.
# For example, I need attach a volume to mysql container.
docker volume create --name mysql-data
docker run --name mysql -v mysql-data:/var/lib/mysql -e MYSQL_ROOT_PASSWORD=my-secret-pw -d mysql
With that, you can delete container mysql any time, without lost your database data.

You can use the -v option to mount a volume (e.g. your folder) into the container. More details can be found in the docs.
E.g., from ghost blog platform's Dockerfile example:
docker run -v /data/ghost:/var/lib/ghost -d ghost
Which maps /data/ghost on the local drive to /var/lib/ghost inside the container.
You can also specify another docker container as the source of the data using --volumes-from option.
