Is CentOS8 will support confluence?
Quick answer: probably; may take a little fiddling.
The friction points are net, when the distro wants to do something the app stack wants otherwise. If I were trying to do an commercial-grade install fast in one shot, I'd allocate a half-day on tap for each of a Centos-Guy, java / app server-guy, and postgresql-guy.
Friction Points (Anybody, correct me if needed):
- Java versions: go with the default confluence install, with bundled run-time. Plan to monitor in case system updates bigfoot that. A "JRE / Tomcat, smart guy" can be useful for app server install and parameters.
- Database, if postgreSQL: go with the distro bundled or sourced package, or the project bundled package for that distro. Postgresql does backward compantibility well. I have always run later versions than Atlassian specifies, with 0 problems. YMMV
- "Just do it", the dbms configs in the setup guide: sort sequence, character encoding, etc. A "postgresql smart guy" is almost required, particularly for identity-wrangling and access. The identity, access, n network visibility is most of where the distro smart-guy is useful, too.
- App client weirdness: can come in if the distro likes or presumes particular browsers or browser configrations.
- System Service Wrangling: is often casual about bigfooting things that aren't done their way; annoying when their way is new, and they blow up backward compatibility. Java, app server, dbms, identity services and more are services that might get bigfooted this way.
- You can get clipped by resource allocation n use monitoring, and service blocking, without immediately knowing it.
This sounds like a lot, but it's typical for any commercial-grade stack. And the Atlassian tools tend to have more transparency than most others, so it's easier to wrangler. YMMV.
