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

• 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

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

• Commands:

  nothing

• Check:

  local:~$ ssh root@localhost -p 9999

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

• Commands:

  nothing

• Check:

  local:~$ ssh [email protected] -p 9999

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

• Commands:

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

• Check:

  local:~$ ssh root@localhost -p 9991

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

• 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
