You can, but it’s complicated. You can search here for “multisite”. A somewhat easier, though less efficient, solution would be to run 4 standalone containers on separate ports and run Nginx or CaddyServer in front of them.
It’s not mandatory, but recommended, for goodies like…
2 more years of support
if you use nginx as a reverse proxy, HTTP2 will work
Discourse only has one version, the awesome version , and it’s on GitHub! It doesn’t come with any plugins (except for some former plugins that are now considered part of core), but installing a plugin is easy and most plugins are free software
The one-click install works, but has some quirks – I’d recommend that you follow our instructions instead, which require no Ruby or Docker experience at all. These instruction should work fine on any VPS host supporting Docker

Keep in mind, unless you’re visiting /admin/upgrade all the time, you’re not on the “bleeding edge”. You’ll be notified when a new point update is released, and that’s usually every few weeks. So not quite “bleeding edge”.
