Step-by-step description of how to run the observer on OS X
The steps described here didn't work for me and it took me quite a bit of fiddling and duckduckgoing around to make the observer work on my machine - I'm running OS X v10.12.3 (16D32). Here's a step-by-step description - mostly take from here - that can be added to the README if you feel it'll help people:
- Make sure the version of the docker image of erlang is >= 19.2
- Install XQuartz if not already installed:
brew install xquartz(at the time of writing the latest version I installed is 2.7.11) - Run XQuartz
- Update preferences 'Security' tab - turn on 'Allow connection from network clients'
- Restart XQuartz and then check to see that it is listening on port 6000:
lsof -i :6000 - Get your local machine's IP:
ip=$(ipconfig getifaddr en0) && echo "My IP is: " + $ip - In the XQuartz terminal run:
xhost + xxx.xxx.xxx.xxx. The output should be something like:xxx.\ xxx.xxx.xxx being added to access control list - Run the docker container:
docker run -it --rm -e DISPLAY=${ip}:0 -v /tmp/.X11-unix:/tmp/.X11-unix erlang
possibly this need special attention; sorry, since I have re-installed Linux on the Mac hardware running natively, I no longer have the osx; will probably find another osx environment soon
👍 for duckduckgoing 😄 .
Just curious, does DISPLAY work for you with localhost:0 instead of the ip?
No localhost doesn't work for me I need to pass the ip

According to https://docs.docker.com/docker-for-mac/networking/, it looks like docker.for.mac.host.internal should always resolve to the host's IP address, but I haven't had a chance to try it yet.
docker.for.mac.host.internal isn't working for me, but the special address 192.168.65.1 appears to be (and I don't need to add anything with xhost). Unfortunately, I'm having a (presumably unrelated) issue where the WX observer app ran once, but has hung every time since.
Never run observer on the Erlang VM which you are running work on - observer crashes all the time and frequently takes down the VM. What's safer is to start a distributed Erlang node, run observer on it, and connect to the VM you want to observe.
