PyCharm add remote Python interpreter inside the Docker

Question

So I have set up a docker on my laptop. I'm using Boot2Docker so I have one level of indirection to access the docker. In PyCharm, I can set a remote python interpreter via SSH but I'm not sure how to do it for dockers that can only be accessed via Boot2Docker?

So your container will have to be running SSH and exposed to the boot2docker/virtualbox host and you connect to the boot2docker/virtualbox host's exposed ssh port via PyCharm to connect up to your remote Python interpreter. — James Mills

Thank you. I'll give it a research on how to forward the SSH. — Sam R.

@JamesMills, thank you so much. Why don't you post it as answer? And what if I run my container as daemon with a webserver running? Can I attach to a running container instead of run cuz I already have run it? — Sam R.

@JamesMills got two downvotes and a close vote with no comment as to why they think so. Weirdos are everywhere. — Sam R.

Okay so to answer your question(s):

In PyCharm, I can set a remote python interpreter via SSH but I'm not sure how to do it for dockers that can only be accessed via Boot2Docker?

You need:

To ensure that you have SSH running in your container

There are many base images that include SSH. See: Dockerizing an SSH Daemon

Expose the SSH service to the Boot2Docker/VirtualBox VM.

docker run -d -p 2222:22 myimage ...
Setup PyCharm to connect to your Boot2Docker/VirtualBox VM.

boot2docker ip

Attaching to a running container is easy too!

$ boot2docker ssh
$ docker exec -i -t <cid> /bin/bash

Where <cid> is the Container ID or Name (if you used --name.

Installed sshd and run the services via supervisord and now I'm able to connect to interpreter. Thanks James.

Did you manage to debug a python class using the remote interpreter? i'm able to connect to the interpreter when running a class, however when trying to debug it fails trying to open additional ports.

What is the failure messages and what ports is it trying to open? (I'm ignorant of PyCharm and I don't actually use it).
