:snowflake: Ryan4Yin's Nix Config :snowflake:
This repository is home to the nix code that builds my systems.
## Why Nix?
Nix allows for easy-to-manage, collaborative, reproducible deployments. This means that once something is setup and configured once, it works forever. If someone else shares their configuration, anyone can make use of it.
**Want to know Nix in detail? Looking for a beginner-friendly tutorial or best practices? Check out [NixOS & Nix Flakes Book - 🛠️ ❤️ An unofficial & opinionated :book: for beginners](https://github.com/ryan4yin/nixos-and-flakes-book)!**
> If you're using macOS, you can also check out [ryan4yin/nix-darwin-kickstarter](https://github.com/ryan4yin/nix-darwin-kickstarter) for a quick start.

## How to Deploy this Flake?
> Note: you should NOT deploy this flake directly on your machine, it contains my hardware information and personal information which is not suitable for you. You may use this repo as a reference to build your own configuration.
After installing NixOS with `nix-command` & `flake` enabled, follow the steps below to deploy this flake.
For NixOS, use the following commands:
```bash
# deploy one of the configuration based on the hostname
sudo nixos-rebuild switch --flake .#ai_i3
# we can also deploy using `make`, which is defined in Makefile
make i3
# or we can deploy with details
make i3-debug
```
For MacOS, use the following commands:
```bash
# deploy the darwin configuration(harmonicia)
make ha
# deploy with details
make ha-debug
```
## Install Apps from Flatpak
We can install apps from flathub, which has a lot of apps that are not supported well in nixpkgs.
```bash
# Add the Flathub repository
flatpak remote-add --if-not-exists flathub https://flathub.org/repo/flathub.flatpakrepo
# install apps from flathub
flatpak install netease-cloud-music-gtk
# install 3d printer slicer - cura
flatpak install flathub com.ultimaker.cura
# or you can search apps from flathub
flatpak search
# search on website is also supported: https://flathub.org/
```
## How to create & managage VM from this flake?
use `aquamarine` as an example, we can create a virtual machine with the following command:
```shell
# 1. generate a proxmox vma image file
nom build .#aquamarine # `nom`(nix-output-monitor) can be replaced by the standard command `nix`
# 2. upload the genereated image to proxmox server's backup directory `/var/lib/vz/dump`
# please replace the vma file name with the one you generated in step 1.
scp result/vzdump-qemu-aquamarine-nixos-23.11.20230603.dd49825.vma.zst root@192.168.5.174:/var/lib/vz/dump
# 3. the image we uploaded will be listed in proxmox web ui's this page: [storage 'local'] -> [backups], we can restore a vm from it via the web ui now.
```
Once the virtual machine `aquamarine` is created, we can deploy updates to it with the following commands:
```shell
# 1. add the ssh key to ssh-agent
ssh-add ~/.ssh/ai-idols
# 2. deploy the configuration to the remote host, using the ssh key we added in step 1
# and the username defaults to `$USER`, it's `ryan` in my case.
nixos-rebuild --flake .#aquamarine --target-host aquamarine --build-host aquamarine switch --use-remote-sudo --verbose
# or we can replace the command above with the following command, which is defined in Makefile
make aqua
```
The commands above will build & deploy the configuration to `aquamarine`, the build process will be executed on `aquamarine` too, and the `--use-remote-sudo` option indicates that we will use `sudo` on the remote host.
