cookiecutter-pycharm-remote-docker

PyCharm project template for development in remote docker environment using Cookiecutter

• You can simplify PyCharm configurations every time and start development with remote docker quickly.
• The Run/Debug configuration of Dockerfile, sample python script, unittest and sphinx document is already created.
• nvidia-docker is supported. It will be useful in a project like Deep Learning and Computer Vision.

Requirements

• Cookiecutter >= 1.4 (install cookiecutter)
• PyCharm Professional >= 2018.2
  • Docker-based interpreters is supported only in PyCharm Professional

Getting Started

Configure the Docker daemon connection settings

In order to connect to remote docker api from PyCharm, you first need to enable remote api of dockerd.This setting is set only once on the remote machine.

Please see the following article and set it up.

• Docker - How do I enable the remote API for dockerd

(Optional) Configuring for using nvidia-docker

If you want to use nvidia-docker, change the default value of docker runtime by making the following settings.

$ sudo vi /etc/docker/daemon.json$ cat /etc/docker/daemon.json{    "default-runtime": "nvidia",    "runtimes": {        "nvidia": {            "path": "nvidia-container-runtime",            "runtimeArgs": []        }    }}$ sudo systemctl daemon-reload$ sudo service docker restart$ docker info | grep -i runtimeRuntimes: nvidia runcDefault Runtime: nvidia #=> OK !

Next, register the remote docker api in PyCharm.

• Add new Docker configuration (e.g. Docker-remote) and set as follows.
  • This name is used later.

Generate Project

Please run cookiecutter [email protected]:tkat0/cookiecutter-pycharm-remote-docker.git

By answering some questions, project directory are automatically generated.

• python_version: python version installed with pyenv.
• timezone: This is set to match the timezone of host and container in the remote server.
• remote_docker_name: You should set the same name set in PyCharm in the previous section (e.g. Docker-remote).
• remote_uid: This is set to match the file permissions of host and container in the remote server.

To change the default value, you can create a config yaml file.

PyCharm Settings

Configuring Synchronization with remote server

• Open Preferences > Build, Execution, Deployment > Deployment and find remote server.
• Enter User name and Password, click Test Connection button and confirm that you can connect.

• To Upload repository to remote server, select project root directory, right click and click Deployment > Upload to remote

By default, changed files automatically upload.If you don't like it, open Build, Execution, Deployment > Deployment > Options and set Upload changed files automatically to the default server to Never

Build docker image on remote server
