pycharm-docker-via-ssh

Connect to a Python interpreter inside the docker container which is running on the remote server

Dockerfile modification

  • Install OpenSSH:

    apt-get update && apt-get install -y openssh-server

  • Create sshd folder. Required to start a SSH daemon:

    mkdir /var/run/sshd

  • Setting a password (current yourpass) that will be used during logging:

    RUN echo 'root:yourpass' | chpasswd

  • Allow logging under the root:

    RUN sed -i 's/PermitRootLogin prohibit-password/PermitRootLogin yes/' /etc/ssh/sshd_config

  • SSH login fix. Otherwise user is kicked off after login:

    RUN sed 's@session\s*required\s*pam_loginuid.so@session optional pam_loginuid.so@g' -i /etc/pam.d/sshd

  • Docker port opening:

    EXPOSE 22

  • Start the SSH service as a daemon:

    CMD ["/usr/sbin/sshd", "-D"]

Docker container start: make build && make run

Use cases

In order to demonstrate, the host port (to docker) is specified as in the Makefile: 9999.

Docker is runnig locally

  • Commands:

    nothing

  • Check:

    local:~$ ssh root@localhost -p 9999

    docker:~$ python /pycharm-docker-via-ssh/src/test.py

Docker is running on the remote ml1 server on the same network

  • Commands:

    nothing

  • Check:

    local:~$ ssh root@xx.xx.xx.xx -p 9999

    docker:~$ python /pycharm-docker-via-ssh/src/test.py

Docker is running on the remote ml1 server on another network

  • Commands:

    local:~$ ssh -L 9991:localhost:9999 ml1

  • Check:

    local:~$ ssh root@localhost -p 9991

    docker:~$ python /pycharm-docker-via-ssh/src/test.py

Docker is running on the remote mlx server, which can be accessed through a ml1 transit server

  • Commands:

    mlx:~$ ssh -R 9992:localhost:9999 ml1

    local:~$ ssh -L 9991:localhost:9992 ml1

  • Check:

    local:~$ ssh root@localhost -p 9991

    docker:~$ python /pycharm-docker-via-ssh/src/test.py

Etc... In the PyCharm configuration, connect to the docker through the localhost and the desired port. Use root username and password which which is defined in Dockerfile
