How to create Discourse mirror in Tor .onion domain?

[Centurion]

Hello!

Sorry for the arrogance, but there is very little information and there is no one to ask.

I saw forum Whonix use Discourse and have .onion mirror. I’m to use Discourse in Docker and try create .onion mirror, but nothing works

Please, maybe you share manual how you can do it?

My steps:

1. apt install tor
2. edit file /etc/tor/torrc

HiddenServiceDir /var/lib/tor/hidden_service/
HiddenServicePort 80 127.0.0.1:8080
HiddenServiceVersion 3

3. restart

systemctl restart tor
systemctl enable tor

4. check my onion domain

cat /var/lib/tor/hidden_service/hostname

5. go to cd /var/discourse/ and edit app.yml
   add templates web.onion.template.yml
   add DISCOURSE_ONION look like:

DISCOURSE_HOSTNAME example.com
DISCOURSE_ONION example.onion

6. ./launcher rebuild app

After these settings, the forum is not available in clearnet and in Tor. Maybe I need change post?
