Prometheus runs as a pod and only has Tailscale routes to the three k8s nodes it runs on (isaiah, jeremiah, zeke) plus hosea. Scraping genesis, exodus, and linode via *.shire-zebra.ts.net fails instantly (~1ms, connection refused) because those Tailscale routes don't exist inside the cluster network. Fix by host type: - k8s nodes (isaiah, jeremiah, zeke, hosea): keep Tailscale hostnames - LAN hosts (genesis): use LAN IP 10.42.1.5 - Roaming/VPS (exodus, linode): use Tailscale IPs directly (100.x.x.x) since they have no fixed LAN address but the k8s nodes do route to other Tailscale IPs via the subnet router Apply same logic to kea, dnsmasq (genesis-only jobs) and the systemd/ping exporter jobs.
This is a unified repo to contain my personal configurations for NixOS machines.
How To Use This
Go through the normal process to setup a NixOS system during installation.
- Boot from an appropriate medium
- Parition the drives
- Mount them
- Before you generate out the configuration, clone this repoistory to your /etc/nixos folder
- Run the configuration generator. It should only genreate the hardware-configuration.nix file, which this repo gitignores
- Create a folder and file with the machine name in
hosts/<machine>/default.nix - Add
hosts/default.nixan appropriate entry for the machine you are building - Create a file
home/hosts/<machine>/default.nixwith the new machine name as well
Adding new hosts
To add a new host, create a folder in the directory hosts/ that matches the name of
the target system. Each host must contain, minimally, a default.nix file that serves
as the basis of configuring that host.
Test build a VM for your system
