Plot R graphics through Docker

docker-compose.yml

version: '3.8'
services:
  
  # The service below does the same as:
  #  docker run -i -t --rm -e DISPLAY=$DISPLAY -u docker -v /tmp/.X11-unix:/tmp/.X11-unix:ro --name="r" rocker/r-base
  # 
  # which can be run with:
  # docker-compose run --rm r
  
  r:
    image: rocker/r-base
    container_name: r
    stdin_open: true # docker run -i
    tty: true        # docker run -t
    user: docker
    environment:
      - DISPLAY=$DISPLAY
    volumes: 
      - "/tmp/.X11-unix:/tmp/.X11-unix:ro"

Plot R graphics through Docker.md

To run the container do:

docker-compose run --rm r

Once you have the container running, enter the command below in the R console to show some graphics

demo(graphics)

If you don't see anything, probably X11 does not have the permission to access the socket, so give it permission by running:

xhost +si:localuser:username

Run the container and demo(graphics) again.
