-# PVV NixOS configs
-
-## Hvordan endre på ting
-
-Før du endrer på ting husk å ikke putte ting som skal være hemmelig uten å først lese seksjonen for hemmeligheter!
-
-Etter å ha klonet prosjektet ned og gjort endringer kan du evaluere configene med:
-
-`nix flake check --keep-going`
-
-før du bygger en maskin med:
-
-`nix build .#<maskinnavn>`
-
-hvis du vil være ekstra sikker på at alt bygger så kan du kjøre:
-
-`nix build .` for å bygge alle de viktige maskinene.
-
-NB: Dette kan ta opp til 30 minutter avhengig av hva som ligger i caches
-
-Husk å hvertfall stage nye filer om du har laget dem!
-
-Om alt bygger fint commit det og push til git repoet.
-Det er sikkert lurt å lage en PR først om du ikke er vandt til nix enda.
-
-Innen 24h skal alle systemene hente ned den nye konfigurasjonen og deploye den.
-
-Du kan tvinge en maskin til å oppdatere seg før dette ved å kjøre:
-`nixos-rebuild switch --update-input nixpkgs --update-input nixpkgs-unstable --no-write-lock-file --refresh --upgrade --flake git+https://git.pvv.ntnu.no/Drift/pvv-nixos-config.git`
-
-som root på maskinen.
-
-Hvis du ikke har lyst til å oppdatere alle pakkene (og kanskje måtte vente en stund!) kan du kjøre
-
-`nixos-rebuild switch --override-input nixpkgs nixpkgs --override-input nixpkgs-unstable nixpkgs-unstable --flake git+https://git.pvv.ntnu.no/Drift/pvv-nixos-config.git`
-
-## Seksjonen for hemmeligheter
-
-For at hemmeligheter ikke skal deles med hele verden i git - eller å være world
-readable i nix-storen, bruker vi [sops-nix](https://github.com/Mic92/sops-nix)
-
-For å legge til secrets kan du kjøre f.eks. `sops secrets/jokum/jokum.yaml`
-Dette vil dekryptere filen og gi deg en text-editor du kan bruke for endre hemmelighetene.
-
-Et nix shell med dette verktøyet inkludert ligger i flaket og shell.nix og kan aktiveres med:
-
-`nix-shell` eller `nix develop`. Vi anbefaler det siste.
-I tilegg kan du sette opp [direnv](https://direnv.net/) slik at dette skjer automatisk
-
-for å få tilgang til å lese/skrive hemmeligheter må du spørre noen/noe som har tilgang til hemmelighetene
-om å legge til age eller pgp nøkkelen din i [`.sops.yaml`](https://git.pvv.ntnu.no/Drift/pvv-nixos-config/src/main/.sops.yaml)
-
-Denne kan du generere fra ssh-nøkkelene dine eller lage en egen nøkkel.
-
-### Legge til flere keys
-
-Gjør det som gir mening i .sops.yml
-
-Etter det kjør `sops updatekeys secrets/host/file.yml`
-
-MERK at det ikke er `sops -r` som BARE roterer nøkklene for de som allerede er i secretfila

+# Miscellaneous development notes
+
+This document contains a bunch of information that is not particularly specific to the pvv nixos config,
+but concerns technologies we use often or gotchas to be aware of when working with NixOS. A lot of the information
+here is already public information spread around the internet, but we've collected some of the items we use often
+here.
+
+## The firewall
+
+`networking.firewall` is a NixOS module that configures `iptables` rules on the machine. It is enabled by default on
+all of our machines, and it can be easy to forget about it when setting up new services, especially when we are the
+ones creating the NixOS module.
+
+When setting up a new service that listens on a TCP or UDP port, make sure to add the appropriate ports to either
+`networking.firewall.allowedTCPPorts` or `networking.firewall.allowedUDPPorts`.
+
+You can list out the current firewall rules by running `sudo iptables -L -n -v` on the machine.
+
+## Finding stuff
+
+Finding stuff, both underlying implementation and usage is absolutely crucial when working on nix.
+Oftentimes, the documentation will be outdated, lacking or just plain out wrong. These are some of
+the techniques we have found to be quite good when working with nix.
+
+### [ripgrep](https://github.com/BurntSushi/ripgrep)
+
+ripgrep (or `rg` for short) is a tool that lets you recursively grep for regex patters in a directory.
+
+It is great for finding references to configuration, and where and how certain things are used. It is
+especially great when working with [nixpkgs](https://github.com/NixOS/nixpkgs), which is quite large.
+
+### GitHub Search
+
+When trying to set up a new service or reconfigure something, it is very common that someone has done it
+before you, but it has never been documented anywhere. A lot of Nix code exists on GitHub, and you can
+easily query it by using the `lang:nix` filter in the search bar.
+
+For example: https://github.com/search?q=lang%3Anix+dibbler&type=code
+
+## rsync
+
+`rsync` is a tool for synchronizing files between machines. It is very useful when transferring large
+amounts of data from a to b. We use it for multiple things, often when data is produced or stored on
+one machine, and we want to process or convert it on another. For example, we use it to transfer gitea
+artifacts, to transfer gallery pictures, to transfer minecraft world data for map rendering, and more.
+
+Along with `rsync`, we often use a lesser known tool called `rrsync`, which you can use inside an ssh
+configuration (`authorized_keys` file) to restrict what paths a user can access when connecting over ssh.
+This is useful both as a security measure, but also to avoid accidental overwrites of files outside the intended
+path. `rrsync` will use chroot to restrict what paths the user can access, as well as refuse to run arbitrary commands.
+
+## `nix repl`
+
+`nix repl` is an interactive REPL for the Nix language. It is very useful for experimenting with Nix code,
+and testing out small snippets of code to make sure it behaves as expected. You can also use it to explore
+NixOS machine configurations, to interactively see that the configuration evaluates to what you expect.
+
+```
+# While in the pvv-nixos-config directory
+nix repl .
+
+# Upon writing out the config path and clickin [Tab], you will get autocompletion suggestions:
+nix-repl> nixosConfigurations.bekkalokk.config.services.nginx.virtualHosts.
+nixosConfigurations.bekkalokk.config.services.nginx.virtualHosts._
+nixosConfigurations.bekkalokk.config.services.nginx.virtualHosts.bekkalokk.pvv.ntnu.no-nixos-metrics

+nixosConfigurations.bekkalokk.config.services.nginx.virtualHosts.www.pvv.ntnu.no
+nixosConfigurations.bekkalokk.config.services.nginx.virtualHosts.www.pvv.org
+```
+
+## `nix why-depends`
+
+If you ever wonder why a certain package is being used as a dependency of another package,
+or another machine, you can use `nix why-depends` to find the dependency path from one package to another.
+This is often useful after updating nixpkgs and finding an error saying that a certain package is insecure,
+broken or whatnot. You can do something like the following
+
+```bash
+# Why does bekkalokk depend on openssl?
+nix why-depends .#nixosConfigurations.bekkalokk.config.system.build.toplevel .#nixosConfigurations.bekkalokk.pkgs.openssl
+
+# Why does bekkalokk's minecraft-server depend on zlib? (this is not real)
+nix why-depends .#nixosConfigurations.bekkalokk.pkgs.minecraft-server .#nixosConfigurations.bekkalokk.pkgs.zlib
+```
+
+## php-fpm
+
+php-fpm (FastCGI Process Manager) is a PHP implementation that is designed for speed and production use. We host a bunch
+of different PHP applications (including our own website), and so we use php-fpm quite a bit. php-fpm typically exposes a
+unix socket that nginx will connect to, and php-fpm will then render php upon web requests forwarded from nginx and return
+it.
+
+php-fpm has a tendency to be a bit hard to debug. It is not always very willing to spit out error messages and logs, and so
+it can be a bit hard to figure out what's up when something goes wrong. You should see some of the commented stuff laying around
+in the website code on bekkalokk for examples of how to configure php-fpm for better logging and error reporting.

+# Development - working on the PVV machines
+
+This document outlines the process of editing our NixOS configurations, and testing and deploying said changes
+to the machines. Most of the information written here is specific to the PVV NixOS configuration, and the topics
+will not really cover the nix code itself in detail. You can find some more resources for that by either following
+the links from the *Upstream documentation* section below, or in [Miscellaneous development notes](./development-misc.md).
+
+## Editing nix files
+
+> [!WARN]
+> Before editing any nix files, make sure to read [Secret management and `sops-nix`](./secret-management.md)!
+> We do not want to add any secrets in plaintext to the nix files, and certainly not commit and publish
+> them into the common public.
+
+The files are plaintext code, written in the [`Nix` language](https://nix.dev/manual/nix/stable/language/).
+
+Below is a list of important files and directories, and a description of what they contain.
+
+### `flake.nix`
+
+The `flake.nix` file is a [nix flake](https://wiki.nixos.org/wiki/Flakes) and makes up the entrypoint of the
+entire configuration. It declares what inputs are used (similar to dependencies), as well as what outputs the
+flake exposes. In our case, the most important outputs are the `nixosConfigurations` (our machine configs), but
+we also expose custom modules, packages, devshells, and more. You can run `nix flake show` to get an overview of
+the outputs (however you will need to [enable the `nix-flakes` experimental option](https://wiki.nixos.org/wiki/Flakes#Setup)).
+
+You will find that a lot of the flake inputs are the different PVV projects that we develop, imported to be hosted
+on the NixOS machines. This makes it easy to deploy changes to these projects, as we can just update the flake input
+to point to a new commit or version, and then rebuild the machines.
+
+A NixOS configuration is usually made with the `nixpkgs.lib.nixosSystem` function, however we have a few custom wrapper
+functions named `nixosConfig` and `stableNixosConfig` that abstracts away some common configuration we want on all our machines.
+
+### `values.nix`
+
+`values.nix` is a somewhat rare pattern in NixOS configurations around the internet. It contains a bunch of constant values
+that we use throughout the configuration, such as IP addresses, DNS names, paths and more. This not only makes it easier to
+change the values should we need to, but it also makes the configuration more readable. Instead of caring what exact IP any
+machine has, you can write `values.machines.name.ipv4` and abstract the details away.
+
+### `base`
+
+The `base` directory contains a bunch of NixOS configuration that is common for all or most machines. Some of the config
+you will find here sets defaults for certain services without enabling them, so that when they are enabled in a machine config,
+we don't need to repeat the same defaults over again. Other parts actually enable certain services that we want on all machines,
+such as `openssh` or the auto upgrade timer.
+
+### Vendoring `modules` and `packages`
+
+Sometimes, we either find that the packages or modules provided by `nixpkgs` is not sufficient for us,
+or that they are bugged in some way that can not be easily overrided. There are also cases where the
+modules or packages does not exist. In these cases, we tend to either copy and modify the modules and
+packages from nixpkgs, or create our own. These modules and packages end up in the top-level `modules`
+and `packages` directories. They are usually exposed in `flake.nix` as flake outputs `nixosModules.<name>`
+and `packages.<platform>.<name>`, and they are usually also added to the machines that need them in the flake.
+
+In order to override or add an extra package, the easiest way is to use an [`overlay`](https://wiki.nixos.org/wiki/Overlays).
+This makes it so that the package from `pkgs.<name>` now refers to the modified variant of the package.
+
+In order to add a module, you can just register it in the modules of the nixos machine.
+In order to override a module, you also have to use `disabledModules = [ "<path-relative-to-nixpkgs/modules>" ];`.
+Use `rg` to find examples of the latter.
+
+Do note that if you believe a new module to be of high enough quality, or the change you are making to be
+relevant for every nix user, you should strongly consider also creating a PR towards nixpkgs. However,
+getting changes made there has a bit higher threshold and takes more time than making changes in the PVV config,
+so feel free to make the changes here first. We can always remove the changes again once the upstreaming is finished.
+
+### `users`, `secrets` and `keys`
+
+For `users`, see [User management](./users.md)
+
+For `secrets` and `keys`, see [Secret management and `sops-nix`](./secret-management.md)
+
+### Collaboration
+
+We use our gitea to collaborate on changes to the nix configuration. Every PVV maintenance member should have
+access to the repository. The usual workflow is that we create a branch for the change we want to make, do a bunch
+of commits and changes, and then open a merge request for review (or just rebase on master if you know what you are doing).
+
+### Upstream documentation
+
+Here are different sources of documentation and stuff that you might find useful while
+writing, editing and debugging nix code.
+
+ - [nixpkgs repository](https://github.com/NixOS/nixpkgs)
+
+This is particularly useful to read the source code, as well as upstreaming pieces of code that we think
+everyone would want
+
+ - [NixOS search](https://search.nixos.org/)
+
+This is useful for searching for both packages and NixOS options.
+
+ - [nixpkgs documentation](https://nixos.org/manual/nixpkgs/stable/)
+ - [NixOS documentation](https://nixos.org/manual/nixos/stable/)
+ - [nix (the tool) documentation](https://nix.dev/manual/nix/stable/)
+
+All of the three above make up the official documentation with all technical
+details about the different pieces that makes up NixOS.
+
+ - [The official NixOS wiki](https://wiki.nixos.org)
+
+User-contributed guides, tips and tricks, and whatever else.
+
+ - [nix.dev](https://nix.dev)
+
+Additional stuff
+
+ - [Noogle](https://noogle.dev)
+
+This is useful when looking for nix functions and packaging helpers.
+

+After editing the nix files on a certain branch, you will want to test and deploy the changes to the machines.
+Unfortunately, we don't really have a good setup for testing for runtime correctness locally, but we can at least
+make sure that the code evaluates and builds correctly before deploying.
+
+To just check that the code evaluates without errors, you can run:
+
+```bash
+nix flake check
+# Or if you want to keep getting all errors before it quits:
+nix flake check --keep-going
+```
+
+> [!NOTE]
+> If you are making changes that involves creating new nix files, remember to `git add` those files before running
+> any nix commands. Nix refuses to acknowledge files that are not either commited or at least staged. It will spit
+> out an error message about not finding the file in question.
+
+### Building machine configurations
+
+To build any specific machine configuration and look at the output, you can run:
+
+```bash
+nix build .#nixosConfigurations.<machine-name>.config.system.build.toplevel
+# or just
+nix build .#<machine-name>
+```
+
+This will create a symlink name `./result` to a directory containing the built NixOS system. It is oftentimes
+the case that config files for certain services only end up in the nix store without being put into `/etc`. If you wish
+to read those files, you can often find them by looking at the systemd unit files in `./result/etc/systemd/system/`.
+(if you are using vim, `gf` or go-to-file while the cursor is over a file path is a useful trick while doing this).
+
+If you have edited something that affects multiple machines, you can also build all important machines at once by running:
+
+```bash
+nix build .#
+```
+
+> [!NOTE]
+> Building all machines at once can take a long time, depending on what has changed and whether you have already
+> built some of the machines recently. Be prepared to wait for up to an hour to build all machines from scratch
+> if this is the first time.
+
+### Deploying to machines
+
+> [!WARN]
+> Be careful to think about state when testing changes against the machines. Sometimes, a certain change
+> can lead to irreversible changes to the data stored on the machine. An example would be a set of database
+> migrations applied when testing a newer version of a service. Unless that service also comes with downwards
+> migrations, you can not go back to the previous version without losing data.
+
+To deploy the changes to a machine, you should first SSH into the machine, and clone the pvv-nixos-config
+repository unless you have already done so. After that, checkout the branch you want to deploy from, and rebuild:
+
+```bash
+# Run this while in the pvv-nixos-config directory
+sudo nixos-rebuild switch --update-input nixpkgs --update-input nixpkgs-unstable --no-write-lock-file --refresh --flake .# --upgrade
+```
+
+This will rebuild the NixOS system on the current branch and switch the system configuration to reflect the new changes.
+
+Note that unless you eventually merge the current changes into `main`, the machine will rebuild itself automatically and
+revert the changes on the next nightly rebuild (tends to happen when everybody is asleep).
+
+### Forcefully reset to `main`
+
+If you ever want to reset a machine to the `main` branch, you can do so by running:
+
+```bash
+nixos-rebuild switch --update-input nixpkgs --update-input nixpkgs-unstable --no-write-lock-file --refresh --upgrade --flake git+https://git.pvv.ntnu.no/Drift/pvv-nixos-config.git
+```
+
+This will ignore the current branch and just pull the latest `main` from the git repository directly from gitea.
+You can also use this command if there are updates on the `main` branch that you want to deploy to the machine without
+waiting for the nightly rebuild.

+# Secret management and `sops-nix`
+
+Nix config is love, nix config is life, and publishing said config to the
+internet is not only a good deed and kinda cool, but also encourages properly
+secured configuration as opposed to [security through obscurity](https://en.wikipedia.org/wiki/Security_through_obscurity).
+That being said, there are some details of the config that we really shouldn't
+share with the general public. In particular, there are so-called *secrets*, that is
+API keys, passwords, tokens, cookie secrets, salts, peppers and jalapenos that we'd
+rather keep to ourselves. However, it is not entirely trivial to do so in the NixOS config.
+For one, we'd have to keep these secrets out of the public git repo somehow, and secondly
+everything that is configured via nix ends up as world readable files (i.e. any user on the
+system can read the file) in `/nix/store`.
+
+In order to solve this, we use a NixOS module called [`sops-nix`](https://github.com/Mic92/sops-nix)
+which uses a technology called [`sops`](https://github.com/getsops/sops) behind the scenes.
+The idea is simple: we encrypt these secrets with a bunch of different keys and store the
+encrypted files in the git repo. First of all, we encrypt the secrets a bunch of time with
+PVV maintenance member's keys, so that we can decrypt and edit the contents. Secondly, we
+encrypt the secrets with the [host keys]() of the NixOS machines, so that they can decrypt
+the secrets. The secrets will be decrypted and stored in a well-known location (usually `/run/secrets`)
+so that they do not end up in the nix store, and are not world readable.
+
+This way, we can both keep the secrets in the git repository and let multiple people edit them,
+but also ensure that they don't end up in the wrong hands.
+
+## Adding a new machine
+
+In order to add a new machine to the nix-sops setup, you should do the following:
+
+```console
+# Create host keys (if they don't already exist)
+ssh-keygen -A -b 4096
+
+# Derive an age-key from the public host key
+nix-shell -p ssh-to-age --run 'cat /etc/ssh/ssh_host_ed25519_key.pub | ssh-to-age'
+
+# Register the age key in .sops.yaml
+vim .sops.yaml
+```
+
+The contents of `.sops.yaml` should look like this:
+
+```yaml
+keys:
+  # Users
+  ...
+
+  # Hosts
+  ...
+  - &host_<machine_name> <public_age_key>
+
+creation_rules:
+  ...
+
+  - path_regex: secrets/<machine_name>/[^/]+\.yaml$
+    key_groups:
+    - age:
+      - *host_<machine_name>
+      - ... user keys
+    - pgp:
+      - ... user keys
+```
+
+> [!NOTE]
+> Take care that all the keys in the `age` and `pgp` sections are prefixed
+> with a `-`, or else sops might try to encrypt the secrets in a way where
+> you need both keys present to decrypt the content. Also, it tends to throw
+> interesting errors when it fails to do so.
+
+```console
+# While cd-ed into the repository, run this to get a shell with the `sops` tool present
+nix-shell
+```
+
+Now you should also be able to edit secrets for this machine by running:
+
+```
+sops secrets/<machine_name>/<machine_name>.yaml
+```
+
+## Adding a user
+
+Adding a user is quite similar to adding a new machine.
+This guide assumes you have already set up SSH keys.
+
+```
+# Derive an age-key from your key
+# (edit the path to the key if it is named something else)
+nix-shell -p ssh-to-age --run 'cat ~/.ssh/id_ed25519.pub | ssh-to-age'
+
+# Register the age key in .sops.yaml
+vim .sops.yaml
+```
+
+The contents of `.sops.yaml` should look like this:
+
+```yaml
+keys:
+  # Users
+  ...
+  - &user_<user_name> <public_age_key>
+
+  # Hosts
+  ...
+
+creation_rules:
+  ...
+
+  # Do this for all the machines you are planning to edit
+  # (or just do it for all machines)
+  - path_regex: secrets/<machine_name>/[^/]+\.yaml$
+    key_groups:
+    - age:
+      - *host_<machine_name>
+      - ... user keys
+      - *host_<user_name>
+    - pgp:
+      - ... user keys
+```
+
+Now that sops is properly configured to recognize the key, you need someone
+who already has access to decrypt all the secrets and re-encrypt them with your
+key. At this point, you should probably [open a PR](https://docs.gitea.com/usage/issues-prs/pull-request)
+and ask someone in PVV maintenance if they can checkout the PR branch, run the following
+command and push the diff back into the PR (and maybe even ask them to merge if you're feeling
+particularly needy).
+
+```console
+sops updatekeys secrets/*/*.yaml
+```
+
+## Updating keys
+
+> [!NOTE]
+> At some point, we found this flag called `sops -r` that seemed to be described to do what
+> `sops updatekeys` does, do not be fooled. This only rotates the "inner key" for those who
+> already have the secrets encrypted with their key.
+
+Updating keys is done with this command:
+
+```console
+sops updatekeys secrets/*/*.yaml
+```
+
+However, there is a small catch. [oysteikt](https://git.pvv.ntnu.no/oysteikt) has kinda been
+getting gray hairs lately, and refuses to use modern technology - he is still stuck using GPG.
+This means that to be able to re-encrypt the sops secrets, you will need to have a gpg keychain
+with his latest public key available. The key has an expiry date, so if he forgets to update it,
+you should send him and angry email and tag him a bunch of times in a gitea issue. If the key
+is up to date, you can do the following:
+
+```console
+# Fetch gpg (unless you have it already)
+nix-shell -p gpg
+
+# Import oysteikts key to the gpg keychain
+gpg --import ./keys/oysteikt.pub
+```
+
+Now you should be able to run the `sops updatekeys` command again.

+# User management
+
+Due to some complications with how NixOS creates users compared to how we used to
+create users with the salt-based setup, the NixOS machine users are created and
+managed separately. We tend to create users on-demand, whenever someone in PVV
+maintenance want to work on the NixOS machines.
+
+## Setting up a new user
+
+You can find the files for the existing users, and thereby examples of user files
+in the [`users`](../users) directory. When creating a new file here, you should name it
+`your-username.nix`, and add *at least* the following contents:
+
+```nix
+{ pkgs, ... }:
+{
+  users.users."<username>" = {
+    isNormalUser = true;
+    extraGroups = [
+      "wheel" # In case you wanna use sudo (you probably do)
+      "nix-builder-users" # Arbitrary access to write to the nix store
+    ];
+
+    # Any packages you frequently use to manage servers go here.
+    # Please don't pull gigantonormous packages here unless you
+    # absolutely need them, and remember that any package can be
+    # pulled via nix-shell if you only use it once in a blue moon.
+    packages = with pkgs; [
+      bottom
+      eza
+    ];
+
+    # Not strictly needed, but we recommend adding your public SSH
+    # key here. If it is not present, you will have to log into the
+    # machine as 'root' before setting your password for every NixOS
+    # machine you have not logged into yet.
+    openssh.authorizedKeys.keys = [
+      "ssh-ed25519 AAAAC3NzaC1lZDI1NTE5AAAAIIjiQ0wg4lpC7YBMAAHoGmgwqHOBi+EUz5mmCymGlIyT my-key"
+    ];
+  };
+}
+```
+
+The file will be picked up automatically, so creating the file and adding the
+contents should be enough to get you registered. You should
+[open a PR](https://docs.gitea.com/usage/issues-prs/pull-request) with the new
+code so the machines will be rebuilt with your user present.
+
+See also [Secret Management](./secret-management.md) for how to add your keys to the
+system that lets us add secrets (API keys, password, etc.) to the NixOS config.
