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?

  • A remote python interpreter a running container? – James Mills Jun 16 '15 at 21:36

    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 Jun 16 '15 at 21:40
  • Thank you. I'll give it a research on how to forward the SSH. – Sam R. Jun 16 '15 at 21:43
  • @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. Jun 16 '15 at 21:47
  • @JamesMills got two downvotes and a close vote with no comment as to why they think so. Weirdos are everywhere. – Sam R. Jun 16 '15 at 22:00
  • I'm upvoting this because this was a good question. 3 people also favourited so I don't know what's going on. – SARose Dec 26 '15 at 01:49

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. – Sam R. Jun 17 '15 at 20:41
  • 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. – Elad92 Jul 02 '15 at 16:36
  • 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*). – James Mills Jul 02 '15 at 23:48
