OTA Updates

[mayankchhabra]

We need a way for the users to reliably update their umbrel node over-the-air.

Whenever a new release of umbrel-compose is made, it should prompt the user on his dashboard about the new update, and should only install the update after the user explicitly confirms.

The update prompt should also include a changelog listing all the changes.

My experience with mender.io didn't bear much fruit in this regard, as mender only allows a maximum of 24 hours for the update to be deployed on a device after it's been released (as their product is focused on IoT devices and not end-user interactive devices).

Nonetheless, the update scripts that I wrote when testing mender's update module can still very much be used by our custom solution.

Or just take a diff of whats on master or a tagged version for docker-compose and apply the patch if the user agrees

So flow would be.

1. Fetch docker-compose to a temporary location (eg. docker-compose.yml.ota)
2. Apply all configuration changes (RPCPASS and RPCPORT) to the file
3. do a diff between the two files and make a patch file
4. If the patch file exists, as the user to do an update

I haven't worked with patch files yet, so not sure how it works. But here was my approach:
https://github.com/mayankchhabra/umbrel-compose/blob/8d61be12f49adbb34c1a7507986939d003c942aa/update-scripts/install.sh#L42

to make a patchfile

diff -u docker-compose.yml docker-compose.yml.new > version.patch

version.patch contains ALL the changes.

Applying the patch

patch docker-compose version.patch
