docker run python from container

Question

I took over a project which requires the usage of docker to setup the development environment. The project wiki is primarily written for use with coreos and one of the setup steps involved running a python script.

I'm using boot2docker and realised that there's no python pre-installed with the tcl. However, the image that I've pulled from the project repository comes with python27.

How do I use the python interpreter from the container without having to type docker exec everytime?

Also, how do I access the project code in the boot2docker vm (not docker) instance locally so that I can do development on an IDE?

Ha, most of the time people want to close Docker questions on SO and send them to SF :) — Adrian Mouat

@Thomasleveil I know. But have a look at the number of Docker questions with a close flag (probably from the same one or two users to be fair). — Adrian Mouat

What about opening a shell in that container instead?

docker exec -it <your container id> /bin/bash -l

and then from there use python.

I'm not using boot2docker myself but from this note, it seems it can be done given that the files on your host are in the /Users (OSX) or C:\Users (Windows) directory

Note: If you are using Boot2Docker, your Docker daemon only has limited access to your OSX/Windows filesystem. Boot2Docker tries to auto-share your /Users (OSX) or C:\Users (Windows) directory - and so you can mount files or directories using docker run -v /Users/<path>:/<container path> ... (OSX) or docker run -v /c/Users/<path>:/<container path ... (Windows). All other paths come from the Boot2Docker virtual machine's filesystem.
