I just wanted to show off a cool project I've found recently. Dashy is a very customizable dashboard that works perfectly for self-hosting projects. You can monitor any service that is reachable via http/https and use widgets like the universal web search interface, I've enabled in my installation.
I only use it as a glorified startup page for my browsers with the search function, but to give you an idea of what's possible, you can take a look at some more creative examples as well.
What's the benefit of having Baikal when you can use Nextcloud's CalDAV/CardDAV?
What is the Nextcloud AIO maintanance for?
Nextcloud AIO is just a link (just the local IP+port) to the maintenance interface of my NC installation. The officially supported docker image of Nextcloud (link here) has a built-in maintenance interface which allows you to update the installation and all dependencies.
Because Nextcloud is more complicated to maintain (especially when you have a lot of apps installed), I have split all that functionality across multiple smaller services. Baikal, WebDAV, Vaultwarden and Freshrss are technically not needed if I use Nextcloud apps, but all of those services are easily configurable as docker containers and if one of them fails, none of the others are affected. If I use Nextcloud for everything and treat it as a monolithic service, I would lose all functionality if the service fails. Because of that, I only use Nextcloud's core functionality, which is syncing files across devices and automatically uploading all the pictures I take with my phone. For everything else, I have a dedicated service that is easier to set up and maintain.
Understood, thank you for the information.
FYI, Syncthing is even lighter on resources if all you need from Nextcloud is syncing across devices.
