VS Code Devcontainer and Docker Image for Coding in R, Python, and Latex

Introduction

This Ubuntu based docker image intends to deliver a fully isolated dev environment for Python, R and Latex. Extend it as needed by adding or removing components.

It's intended that you use this image with a VS Code Devcontainer. VS Code will automatically install all required extensions for code formatting, linting, execution and debugging.

Contents

  • R 4.X.X
  • Texlive 2020.X
  • Python 3.8.X

Setup using VS-Code

System requirements

Getting Started

  • Fork the berrij/devenv github repository.
  • Clone the forked repository.
  • Open the repository inside VS Code and install the recommended extensions.
  • VS Code should ask you if you want to reopen the workspace in a container. It will automatically download the latest master build, install extensions, and mount your current workspace.

SSH and GPG Keys

Look here on how to forward your lokal keys into the container.

Without VS-Code:

You may need to run:

xhost local:root

locally to grant access to the local x11 display server. This is necessary for R graphics devices to work.

Run using:

docker run -it --rm --network=host -e DISPLAY -v /tmp/.X11-unix:/tmp/.X11-unix dev_env:latest

Explanation:

-it             
# Interactive Mode, launches a shell

--rm            
# Automatically remove the container when it exits

--network=host  
# Configures the network of the Docker container to use   the host network. This is the simplest way to get access to X11

-e DISPLAY      
# Sets the DISPLAY variable to :0. Works ins most cases.

-v /tmp/.X11-unix:/tmp/.X11-unix dev_env:latest
# Mounts the local .x11 server into the container

Remove Old Docker Images

You likely want to add a cronjob to delete old docker images and containers. You can do so the following way:

Edit your crontab with:

crontab -e

Then add the following line:

* */6 * * * /usr/bin/docker system prune -a --force --filter "until=240h"

This will remove all unused images not just dangling ones as long as they are older than 10 days.
