Discourse + ActivityPub plugin

[rmdes]

There is a new plugin for Discourse that make each category available as an "actor" that can be followed on the fediverse. (NodeBB is also getting there by the way)
so I was wondering if it could be possible to package it by default, so that each server admin could enable it if they wish so ?

the plugin dropped on the discourse main forum 8 days ago : https://meta.discourse.org/t/activitypub-plugin/266794
here are the how to install plugins : https://meta.discourse.org/t/install-plugins-in-discourse/19157
here is the code of the plugin itself : https://github.com/discourse/discourse-activity-pub

I have not tested this locally or anything, but it appears that the plugin could be packaged and enabled on demand ?

Can't you install it anyway? Not sure how that works on Cloudron

[rmdes]

@murgero Trying now, will document it here

So apparently it installs but then, it fails the migration, but I'm not sure it's because of the plugin, I've seen these errors popup when I installed this fresh discourse instance :
for some reasons it fails to connect to the mongodb service or something similar, but again, this was even before touching the plugin install..
something is odd, because this is a fresh install.
still investigating

cd /app/code/plugins
git clone https://github.com/discourse/discourse-activity-pub
cd /app/code
bundle exec rake plugin:install_gems['discourse-activity-pub'] 

# the line below will force assets to be rebuilt on next application restart
rm -rf /run/discourse/public/assets/*

I've checked the full log, since the app install, and even during the installation steps, it was outputting this kind of errors

2023-06-23T14:51:30.000Z => Healtheck error: Error: connect ECONNREFUSED 172.18.20.85:80
2023-06-23T14:51:40.000Z => Healtheck error: Error: connect ECONNREFUSED 172.18.20.85:80

2023-06-23T14:51:50.000Z => Healtheck error: Error: connect ECONNREFUSED 172.18.20.85:80

not sure if it's related, but this error keeps going, even tho I managed to login, change root email etc..

@rmdes For discourse, I would hold on a bit since it has issue with installing plugins in general. Discourse has moved on to 3.0 and needs redis 7. The new Cloudron releas will bring Redis 7. Our e2e has almost passed, so a Cloudron release will happen soon.

oh neat !! I'll wait, this is nothing urgent, just curious to see what forums/activitypub could do in the current reddit mess
