Resources

Images

This image was created in order to be used in a CI/CD environment like Gitlab CI or Travis, so that you don't have to reinstall testing and dev packages.

For an RStudio session from the browser

Point your browser to localhost:8787 and login with the username "rstudio" and the PASSWORD=123. You should now have running RStudio session, and access to the directory (-v for volume) you mounted.

For package development

Commit a new image from a container

# Find the container you want to commit
docker ps
docker commit -m "<optional message>" <container's sha> <new image's name>

Tips for windows users

• What works on Unix systems may not work on Windows, and typing paths "like/this" works better than like/this.
• PowerShell terminal often works better than other terminals. Sometimes it works well to first launch a bash terminal.

Start by reviewing the Docker and R resources, images, commands, and Windows notes listed in the issue. No repository file, test, or specific documentation change is identified, so the scope and completion criteria would need to be established before implementation.
