Notes on Nextcloud (App nextcloud)¶
How to install Nextcloud “apps”¶
First, let’s be clear about our terminology:
- In UBOS terminology, Nextcloud is an App, like Wordpress or Mediawiki.
- In UBOS terminology, anything that adds functionality to an App is called an Accessory.
- Nextcloud doesn’t call itself an app. Instead, it calls code that adds functionality to Nextcloud (like the Nextcloud calendar or address book) an app.
Armed with this understanding, how does one install what Nextcloud calls an app, and what UBOS calls a Nextcloud Accessory? Usually, you would log into your Nextcloud installation as administrator, navigating to the “apps” pages, and pick install new ones from there.
This is not how it works on UBOS.
Example: let’s say you want to use the Nextcloud “Calendar” app for your Site. When you create the Site with ubos-admin createsite, you specify nextcloud as your app, and nextcloud-calendar as an Accessory. You can specify multiple Accessories.
Here’s the reason why: UBOS cannot manage Apps that change their code base without UBOS knowing, and that’s what would be happening if Nextcloud got to add “apps” aka Accessories to itself. And: UBOS curates Accessories, so you can be fairly certain that the ones provided through UBOS actually work.
