## Prerequisites
|
2023-11-05 18:03:44 +00:00
|
|
|
|
2023-11-15 12:24:06 +00:00
|
|
|
1. Install the Nix package manager or NixOS ([link](https://nixos.org/download))
|
|
|
|
|
2. Enable flake and nix commands ([link](https://nixos.wiki/wiki/Flakes#Enable_flakes_permanently_in_NixOS))

## Bootstrapping
|

|
|
We bootstrap our servers using [nixos-anywhere](https://github.com/nix-community/nixos-anywhere).
|
2023-11-15 12:24:06 +00:00
|
|
|
This reformats the hard disk of the server and installs a fresh NixOS.
|
|
|
|
|
Additionally, it deploys an age identity, which is later used for decrypting secrets.

⚠️ This will wipe your server completely ⚠️

|
|
|
1. Make sure you can decrypt the Sops-encrypted secrets in `secrets/`. You can test this by running `sops -d secrets/serverKeys.yaml`.
|
2023-11-15 12:24:06 +00:00
|
|
|
2. Ensure you have root SSH access to the server.
|

|
|
|
3. Run nixos-anywhere: `nix run '.#bootstrap' <servername> <hostname>`

|
To deploy all servers at once: `nix run 'nixpkgs#deploy-rs' -- '.#' -k`
|
|
|
|
|
To deploy only one server: `nix run 'nixpkgs#deploy-rs' -- -k --targets '.#<host>'`

## Known bugs

|
### Rsync not available during bootstrap
|
|
|
|
|
|
|
|
|
|
The `rsync` command was removed from recent NixOS ISO which causes nixos-anywhere to fail when copying extra files.
|
|
|
|
|
See [this](https://github.com/nix-community/nixos-anywhere/issues/260) issue.
|
|
|
|
|
Solution is to execute `nix-env -iA nixos.rsync` on the host.
