Am I the only person left who simply has a web server? Untar Mediawiki, edit a few config variables, run an established database script, and off you go. Maybe I'm wildly out of touch, but I don't see why everything has to be a container or a monthly paid service around here.
I get it for something like an email server, where misconfiguration could lead to your server being a zombie, but I don't get it for something like a wiki.
