Run the image on mac

On mac, first make sure XQuartz is running

open -a XQuartz
# In XQuartz -> Preferences > Security, make sure the tick "Allow connections from network clients" is ON.

Then set DISPLAY options. Verifu

# Its either of these. Check which one return IP addr.
ipconfig getifaddr en1
ipconfig getifaddr en0

# Run appropriate
xhost + `ipconfig getifaddr en1`
xhost + `ipconfig getifaddr en0`

Then make alias and run

alias dr='docker run -ti --rm -e DISPLAY=$(ipconfig getifaddr en1):0 -v /tmp/.X11-unix:/tmp/.X11-unix -v $PWD:/home/developer/work --name ubuntu_relax tlinnet/docker_relax'

# Start relax
dr relax

# Start relax in GUI
dr relax -g

# Start OpenDX
dr dx

# Try OpenMPI
dr mpirun --version
dr mpirun -np 2 echo "hello world"
dr mpirun --report-bindings -np 2 echo "hello world"

To make this easier, consider adding this to HOME/.bash_profile

# Start docker, if it is not running
alias drdocker='open -a /Applications/Docker.app/Contents/MacOS/Docker'
# Start  XQuartz, if it is not running
alias drx='open -a XQuartz; xhost + `ipconfig getifaddr en1`'
# Alias the docker run command
alias dr='docker run -ti --rm -e DISPLAY=$(ipconfig getifaddr en1):0 -v /tmp/.X11-unix:/tmp/.X11-unix -v $PWD:/home/developer/work --name ubuntu_relax tlinnet/docker_relax'
