"Atleast" isn't a word.
I looked at wiki.js and I don't understand why you wouldn't just install Mediawiki. It only takes a few minutes and wiki.js doesn't look any more sophisticated at a glance.
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.
There are still plenty of not sane container builds that don't make it easy. If I need to checkout a git repo and mount a path into the container it's not sane. Pulling an image and starting a docker-compose should be all that's needed.
The only reason I recommended DO is it’s just simple and not too expensive. But your point is fair.
