# docker build -t emacs29:ubuntu -f emacs29-ubuntu.dockerfile .
# docker run --rm -d --name emacs -eDISPLAY=$DISPLAY -v /tmp/.X11-unix/:/tmp/.X11-unix/ -t emacs29:ubuntu
# You can mount your host directory if you need:
   # docker run --rm -d --name emacs -eDISPLAY=$DISPLAY  -v /path/to/host/dir:/path/inside/container  -v /tmp/.X11-unix/:/tmp/.X11-unix/ -t emacs29:ubuntu
   # this assumes your host user id (i.e. 1000) exists in container
# docker exec -it emacs bash OR docker exec -u 0 -it emacs bash (to login as root)
# Then simply do `doom run`

# Once this container is running, you can either run emacs from within it or copy /opt/emacs folder to your host and run emacs from there.
# If you do the latter, make sure to do `export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/opt/emacs/shared-libs` first.
# Copying from container to host will only work if both have same glibc version.
#   In order to find glic version, run this command on host and guest: `ldd --version`
