# Nixified BBB Demo
reproducible development and maintainment
---
### Goals
- Universal development environment
- Usage of Nix development environment
- Reproducible Containerbuilds
- Usage of Nix DockerImage
- Pkging for NixOS
---
### First of all
- What is Nix?
---
- How does it work?
---
---
---
### Enter the development environment
```bash
nix develop
```
---
### Reproducible Containerbuilds
Issue with Docker
---
Most package managers will write files to shared global directories like /usr, /bin, and /etc.
As a user you might manually create rules to improve the behavior of the cache: add your code towards the end of a Dockerfile, or install common libraries in a single RUN instruction, even if thy don’t want them all.

Building Docker Image with Nix
```bash
{
inputs = {
docker-nixpkgs = {
url = "github:nix-community/docker-nixpkgs";
flake = false;
};
flake-utils.url = "github:numtide/flake-utils";
nixpkgs.url = "github:NixOS/nixpkgs";
};
outputs = { self, docker-nixpkgs, flake-utils, nixpkgs }:
let
system = "x86_64-linux";
pkgs = import nixpkgs { inherit system; };
buildImageWithNix = import ("${docker-nixpkgs}" + "/images/nix/default.nix");
in rec {
# TODO ADD nginx
packages.nixImage = buildImageWithNix {
# All of this is required by the function
inherit (pkgs)
dockerTools
bashInteractive
coreutils
nix
xz;
# TODO add BBB config
extraContents = with pkgs; [
];
};
packages.default = pkgs.dockerTools.buildImage {
fromImage = packages.nixImage;
# ...
};
};
}
```

### Nixpkging for BBB in
- [Current Development](https://github.com/yVieta/bbb4nix)
- Moduls have to be build
---
#### Install nix ontop if your System
https://nixos.org/download#nix-install-linux
---
#### Usefull tools
- [FlakeHub CLI](https://github.com/DeterminateSystems/fh): Creating development environmens
- [Nixpacks](https://github.com/railwayapp/nixpacks): Applications transform to docker Images
- [Arion](https://github.com/hercules-ci/arion): Docker Compose with nix
- https://docs.hercules-ci.com/arion/
---
#### Work in progress
- Container build with nix: https://github.com/yVieta/bbb-container
- Flake build : https://github.com/yVieta/bigbluebutton
- Rewrite for porting to official Nixpkgs: https://github.com/yVieta/bbb4nix
