Deuxfleurs on NixOS!

This repository contains code to run Deuxfleur's infrastructure on NixOS.

It sets up the following:

  • A Wireguard mesh between all nodes
  • Consul, with TLS
  • Nomad, with TLS

The following scripts are available here:

  • deploy_nixos, the main script that updates the NixOS config
  • genpki.sh, a script to generate Consul and Nomad's TLS PKI (run this once only)
  • deploy_pki, a script that sets up all of the TLS secrets
  • upgrade_nixos, a script to upgrade NixOS
  • tlsproxy.sh, a script that allows non-TLS access to the TLS-secured Consul and Nomad, by running a simple local proxy with socat
  • tlsenv.sh, a script to be sourced (source tlsenv.sh) that configures the correct environment variables to use the Nomad and Consul CLI tools with TLS

Stuff should be started in this order:

  • app/core
  • app/frontend
  • app/garage-staging

At this point, we are able to have a systemd service called mountgarage that mounts Garage buckets in /mnt/garage-staging. This is used by the following services that can be launched afterwards:

  • app/im
