I'm on Linux Arch (Antergos to be precise). Output: Chrome is there. I then tried to start it manually in the shell of the container: # /usr/bin/google-chrome-beta --headless --disable-gpu --remote-debugging-port=9222

Seems the cause is that arch doesn't have userspaces enabled by default. And the arch devs say this isn't going to change by default: https://bugs.archlinux.org/task/36969 That means if I want to use the docker container with arch I have to change my kernel config or run it with "open doors" if I get this right. As my arch machine is only for development I will not change my kernel and just run this project locally without docker. That does it for me. Feel free to close this issue if you don't want to dig deeper into this. |

Seems like the express server can't connect to the chrome dev tools interface?!
