X11 Dockerfile README
This Dockerfile just provides an example of what libraries should be added to have a functioning X11 system. Note that using X11 windows from Docker requires X11 be installed and linked on the host; this can be non-trivial, particularly on non-Linux hosts.
On a Ubuntu Linux host, I find the following command works. Note that we can use the R function capabilities()
to confirm X11 support.
As this Dockerfile is just here for illustrative purposes, there is no pre-built or version-tagged image for X11 on the Hub, but the image can be quickly built from the Dockerfile here.
docker build -t rocker/x11 .
XSOCK=/tmp/.X11-unix && XAUTH=/tmp/.docker.xauth && xauth nlist :0 | sed -e "s/^..../ffff/" | xauth -f $XAUTH nmerge - && docker run -v $XSOCK:$XSOCK -v $XAUTH:$XAUTH -e XAUTHORITY=$XAUTH -e DISPLAY=$DISPLAY --rm -it rocker/x11 R -e "capabilities()"
