Install Discourse for Development using Docker is Failed

I fail…
Install Discourse for Development using Docker

  • clone Discourse
git clone https://github.com/discourse/discourse.git ~/discourse
  • start dev
cd discourse
./bin/docker/boot_dev --init
./bin/docker/unicorn

open a browser on http://localhost:9777 and I don’t should see Discourse.
why??

(It was changed to 9777 due to port collision.)

Detail :

y@y-VirtualBox:~/discourse$ sudo ./bin/docker/unicorn -x

Is it running?

Looks like it to me. Have you checked for port 9777 being closed on the dev machine?

docker stop discourse_dev??

I don’t know
Please explain

9777 포트 제대로 열려있는지 확인 하시랍니다.

netstat -nl | grep 9777

하셔서 뭔가 걸리는게 있는지 확인 해 보세요.

Originally, the crash occurred at 9292, and it was changed to 9777
