PyCharm SDK using Docker

The image is built by defining the user of the host system. We could use /etc/passwd and /etc/group but if home path of users is exotic or shell not defined in image, it could not work. For shake of simplicity, we define a user inside the docker. If a volume is mounted, the user should have same uid/gid than on the host.

The command id helps to find user's informations :

id -un # name of user
id -u  # UID
id -gn # name of main group
id -g  # GID    

To build the image (behind a proxy) :

docker build -t pycharm \
  --build-arg http_proxy=${http_proxy} \
  --build-arg https_proxy=${https_proxy} \
  --build-arg ftp_proxy=${ftp_proxy} \
  --build-arg no_proxy=${no_proxy} \
  --build-arg user=$(id -un) \
  --build-arg uid=$(id -u) \
  --build-arg group=$(id -gn) \
  --build-arg gid=$(id -g) \
  .

We can use docker-compose but variables are not expanded.

To run the image :

docker run -it --rm \
  --name pycharm
  -e DISPLAY=$(uname -n):0.0 \
  -v ${HOME}:/home/$(id -un) \
  pycharm

X server should be enabled
