nixos-config

Initial nixos configs. I don’t really know what I’m doing.

Notes:

  • This repo should be checked out to $HOME/nixos-config
  • /etc/nixos/ should be empty except for a symlink to $HOME/nixos-config/flake.nix
  • nixos-rebuild switch should then work without extra args due to the above symlink
  • Same as nixos-rebuild switch --flake $HOME/nixos-config/#
  • nix flake update to update the lock file
  • System specific configs go in nixos-config/systems/<hostname>/default.nix and then imported in flake.nix
  • nix fmt to format entire flake using configured formatter (alejandra)
  • Docker containers are run via Arion, which generates and runs (via systemd units) docker-compose files

Proxmox

Generate a Proxmox LXC CT template

nix run github:nix-community/nixos-generators -- --format proxmox-lxc
  • If we don’t have a local nix install handy, but do have docker installed:
docker run --name nix_generators -it nixos/nix nix run --extra-experimental-features "nix-command flakes" github:nix-community/nixos-generators -- --format proxmox-lxc
docker cp nix_generators:/nix/store/dsl5vzvb1y9ifjf24mkc9ibra7yymp4z-tarball/tarball/nixos-system-x86_64-linux.tar.xz .  # replace with path from command above
docker rm nix_generators
  • Then load the template into proxmox and create a new container, etc…

Generate a Proxmox image

nix build .#nix-shitfucker
# Image generated to ./result/vzdump-qemu-nix-shitfucker.vma.zst
scp ./result/vzdump-qemu-nix-shitfucker.vma.zst pve:/mnt/pve/sh2-nfs/dump/
ssh pve qmrestore /mnt/pve/sh2-nfs/dump/vzdump-qemu-nix-shitfucker.vma.zst 130 --unique true
