Discourse on a Raspberry Pi | Blog

Maybe hardcode that IP in your local hosts file?


Thanks Falco! I will check that out.


I tried hardcode the IP in my client’s hosts file, and the browser always redirect me to the external connection.
Is it possible to provide more than one domain name to the DISCOURSE_HOSTNAME?
Do i need to set DISCOURSE_FORCE_HTTPS: to false to allow local connection? I got this from one of your article.

I am trying to install Discourse on my Raspberry Pi 4 using Dietpi OS and some apps working with Nginx like Nextcloud. I am trying to use Cloudflared service as a tunnel but after the Discourse installation is complete I can’t access Discourse site and i got 502 bad gateway error.

What kind of customization is required on Nginx? Which port should we use?

I applied this guide but without success

My guide assumes that Discourse is the only app on the Pi, and then runs the tunnel exposing the port 80 that is assigned to the Discourse container.

Running multiple apps that share a reverse proxy, while possible, is a more advanced setup and out of the scope of this guide.

I got this working by setting DISCOURSE_BACKUP_HOSTNAME to machinename.local and DISCOURSE_FORCE_HTTPS to false. Now i can access with my domain name and local network domain name.


Well done. Maybe should be a How To in #howto:admins ?

Thanks @merefield. Sure!
There is one problem when using a backup hostname, the images doesn’t display properly.
If the post’s images created with main hostname and when access with the backup hostname, the images will be missing. This also happens in vice-versa.

What happens when you rebake a Post? (Rebuild HTML)

Perhaps you will need to stick to one access address.

Yeah, Rebuild HTML works. But the vpn access is broken because it depends on the local address (backup hostname).

i guess there is no solution to this…

Will this work on an armv7l?

No it won’t. I did try, but there are some missing packages on the 32 bit ARM debian repositories that made it a no go.
