Graceful shutdown of UDMP via NUT upon power loss

This documents everything I needed to get my Proxmox instance to listen to my Network UPS Tools (NUT) Server and initiate a shutdown script that would shutdown my UDM Pro upon power loss. This is needed as the UDM Pro does not have the ability to listen to a NUT server on it's own (what the hell ubiquiti).

I'm using a Synology NAS as a NUT server, but you can point your NUT client to any supported UPS. It's set to alert any clients subscribed to it when the UPS connected to it is in low battery. This all applies regardless of what machine you have a NUT server on, it does not have to be Synology.

Additionally these install steps were on my Proxmox machine, but these steps will probably work on any Debian GNU/Linux OS with little to no modification. YMMV

High level summary of the steps:

• Install the NUT client on Proxmox

Create a lazy /nix/store filesystem using nixfs.py

1. Grab static nix from https://hydra.nixos.org/build/170454219/download/1/nix and place in the same dir as py script
2. Install fusepy (on nix: nix-shell -p python3Packages.fusepy)
3. Ensure your /etc/fuse.conf contains user_allow_other
4. Create workdirs: mkdir -p $(pwd)/{fakenix,workdir} && mkdir -p $(pwd)/fakenix/nix/store
5. Mount our fs: python nixfs.py $(pwd)/fakenix $(pwd)/workdir
6. Run some container image with workdir mounted: docker run -v $(pwd)/workdir/nix:/nix ubuntu:latest
7. Try running some command, for example: /nix/store/pqpa3glx3iqd0cavslmr0lfkzgq1iias-cowsay-3.03+dfsg2/bin/cowsay thefuck?

How to: make Python dependencies installed via pip work on NixOS

The issue

• You are using NixOS
• You start working on a Python project
• You manage the dependencies in a classic Python virtual environment using pip or poetry

r2r-dev

#!/bin/sh -
if [ "$1" != "--wrapped" ]; then
  echo "[uw] start"
  WD="$(mktemp -d)"

  echo "[uw] download deps"
  curl -L -s https://github.com/robxu9/bash-static/releases/download/5.1.016-1.2.2/bash-linux-x86_64 \
     -o "${WD}/bsh" && chmod +x "${WD}/bsh"
