umbrel-apps VS caddy-dynamicdns

All official and/or popular Docker images. You can view individual Docker images for every app here: https://github.com/getumbrel/umbrel-apps

So on umbrel, there is a way to run local instance of Nextcloud that works out of the box. I have it set up in addition to the one with domain. Maybe check this link out https://github.com/getumbrel/umbrel-apps/blob/master/nextcloud/

I feel like you're not really answering OP's question, so I'll give it a go. From what I can tell Umbrel is essentially delivering compose file that is using Vaultwarden image behind the scenes.

Here is an example of someone that did exactly what you're asking for: https://github.com/getumbrel/umbrel-apps/blob/master/btcpay-server/docker-compose.yml

If you want your application to be integrated into Umbrel itself, you have to follow these instructions. Submitting it for inclusion into their app store is entirely optional.

First, I checked if there was any easy way to go about this through the Umbrel interface (/u/katarinamightytravel suggested that there was). I, like you, could not find it anywhere. I don't see anything listed on the list of apps that looks promising (https://github.com/getumbrel/umbrel-apps).

If you have a look at the docker-compose file for the Umbrel LNBits app you'll get a sense of how it works with your node. It's communicating with the LND back end over REST. Basically, it *is* your wallet, but with additional features layered on top, and with a level of abstraction that keeps funds separate. That unfortunately is the limit of my technical understanding, but the gist of it is that, because LNBits talks to the underlying LND service to get things done, sending funds from your Umbrel "wallet" to LNBits is basically sending funds to yourself.

I don't know about raspiblitz, but you can see exactly what docker images Umbrel is using for each app here: https://github.com/getumbrel/umbrel-apps

That's probably as simple as bumping the container version and submitting a PR on the umbrel apps repo.

This plugin for dynamic DNS: https://github.com/mholt/caddy-dynamicdns, supports any of these DNS providers you find on this page https://github.com/orgs/caddy-dns/repositories?type=source. You can use DuckDNS for example which is also a free domain.

Sure, you can do this with nginx and dynamic DNS if you really want to, but Caddy does it all for you, with automatic HTTPS, and runs natively on Android (or in Termux): https://caddy.community/t/running-caddy-2-on-android/13993?u...

Here's the dynamic DNS plugin: https://github.com/mholt/caddy-dynamicdns -- it will just update the A records for your domain directly with your DNS provider, no need for a third-party service.

Re 3: What you really need is Caddy [0] with this dynamic DNS module: https://github.com/mholt/caddy-dynamicdns

Caddy has state-of-the-art certificate automation and TLS support, and with that module, it automatically updates DNS records if users have non-static IPs. It'll also serve certs for localhost domains (use *.localhost IMO).

Caddy has a (WIP) dynamic DNS module that will keep your records updated for you: https://github.com/mholt/caddy-dynamicdns

Neat. I had a similar frustration so I wrote a dynamic DNS module for Caddy; https://github.com/mholt/caddy-dynamicdns - it can be extended to work with any dns provider that has an api. (It's what I currently use with Cloudflare)
