- reverse proxy with wireguard tunnel
- restic
- static wireguard mesh
- unified guests interface for microvms and containers with ZFS integration
- zoned nftables
- Secret rekeying, generation and bootstrapping using agenix-rekey
- Remote-unlockable full disk encryption using ZFS on LUKS
- Automatic disk partitioning via disko
- Support for repository-wide secrets at evaluation time (hides PII like MACs)
If you are interested in parts of my configuration,
you probably want to examine the contents of users/, config/, modules/ and hosts/.
Also, a lot of interesting modules have been moved to nixos-extra-modules, a separate repository specifically for reusable stuff.
The full structure of this flake is described in STRUCTURE.md,
but here's a quick breakdown of the what you will find where.
config/ |
global configuration for all hosts |
config/optional/ |
optional configuration included by hosts |
hosts/<hostname> |
top-level configuration for <hostname> |
modules/ |
classical reusable configuration modules |
nix/ |
library functions and flake plumbing |
pkgs/ |
Custom packages and scripts |
secrets/ |
Global secrets and age identities |
users/ |
User configuration and dotfiles |
... incomplete.
- Add to
hostsinflake.nix - Create hosts/
- Fill net.nix
- Fill fs.nix (you need to know the device /dev/by-id paths in advance for partitioning to work!)
- Run
agenix generateandagenix rekey(create's dummy secrets for initial deploy)
- Create a bootable iso disk image with
nix build --print-out-paths --no-link .#images.<target-system>.live-iso, dd it to a stick and boot - (Alternative) Use an official NixOS live-iso and setup ssh manually
- Copy the installer from a local machine to the live system with
nix copy --to <target> .#nixosConfigurationsMinimal.config.system.build.installFromLive
Afterwards:
- Run
install-systemin the live environment, export your zfs pools and reboot - Retrieve the new host identity by using
ssh-keyscan <host/ip> | grep -o 'ssh-ed25519.*' > hosts/<host>/secrets/host.pub - (If the host has guests, also retrieve their identities!)
- Rekey the secrets for the new identity
nix run .#rekey - Deploy again
...
- Generate, edit and rekey secrets with
agenix <generate|edit|rekey>
To be able to decrypt the repository-wide secrets (files that contain my PII and are thus hidden from public view),
you will need to (be me and) add nix-plugins and point it to ./nix/extra-builtins.nix.
The devshell will do this for you automatically. If this doesn't work for any reason, this can also be done manually:
- Get nix-plugins:
NIX_PLUGINS=$(nix build --print-out-paths --no-link nixpkgs#nix-plugins) - Run all commands with
--option plugin-files "$NIX_PLUGINS"/lib/nix/plugins --option extra-builtins-file ./nix/extra-builtins.nix
Generate self-signed cert, e.g. for kanidm internal communication to proxy:
openssl req -x509 -newkey rsa:4096 -sha256 -days 3650 -nodes \
-keyout selfcert.key -out selfcert.crt -subj \
"/CN=example.com" -addext "subjectAltName=DNS:example.com,DNS:sub1.example.com,DNS:sub2.example.com,IP:10.0.0.1"
