Hmmm… Looks like this has already been attempted here: Anyone got DokuWiki integrated with Nextcloud?
But I don’t really see any movement on this. A flatfile wiki seems like a natural fit for cloud hosting. Could possibly allow for something in workflow to Nuclino, which is a cloud based wiki:
Despite not having a MYSQL requirement, DokuWiki still requires Apache to run on a web server. You can run DokuWiki as a Bitnami instance on your own desktop, but there are many files required as part of install. Then there all the plugins. And if running the Bootstrap 3 framework, even more. I’d love it if there could be integration but I’m not wasting my breath on it.
