On one hand, this is incredibly cool, and brings some great security.

On the other hand, docker containers on a RPi Zero? What a sad state of affairs we have in 2022.

Why?

Sincere question - AFAIK, Raspberry PI OS is a Linux distribution like any other, with dependency/distribution issues like any other. Why would using Docker on it be a sad state of affairs, in contrast to using it on any other distribution?

Not the OP but maybe bec this is a single use device… why not just install direct on the OS and back the whole thing up?

One reason is that software isn't always distributed in normal distro repositories anymore. People can't (or don't want to) deal with dependency management so they ship an entire (slightly outdated version of an) OS with their application to make deployment foolproof.

The vaultwarden install instructions assume Docker, for example: https://github.com/dani-garcia/vaultwarden. If you want to install native binaries, you're going to have to git fetch/checkout/pull the latest release tag and run `cargo build --features sqlite --release` yourself. Doable in a cronjob, but it'll probably take a compile to build a system like vaultwarden on a low-power ARM core.
