Obtain the latest stable image with:

docker pull ghcr.io/berrij/devenv:latest

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 is 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.

• R 4.X.X
• Texlive 2022
• Python 3.8.X

• Install Git
• Install VS-Code
• Install Docker Desktop

• 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.

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

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.

docker run -it --rm --network=host -e DISPLAY -v /tmp/.X11-unix:/tmp/.X11-unix ghcr.io/berrij/devenv:dev

-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

You can check the disk usage of Docker by running:

docker system df

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:

0 18 * * 5 /usr/bin/docker system prune --all --volumes --force

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

When using this image with the .devcontainer.json as a devcontainer, a local volume extensions_cache / extensions_cache_insiders will be created for storing container extensions between container runs. If extensions are updated in the .devcontainer.json this volume has to be deleted:

docker volume rm extensions_cache
docker volume rm extensions_cache_insiders
