+this repository nxios configurations of the digital malobeo infrastructure. it should be used to setup, test, build and deploy different hosts in a reproducible manner.
+
+the file structure is based on this [blog post](https://samleathers.com/posts/2022-02-03-my-new-network-and-deploy-rs.html)
+
+## hosts
+
+#### durruti
+- nixos-container running on dedicated hetzner server
+- login via ```ssh -p 222 malobeo@dynamicdiscord.de```
+- if rebuild switch fails due to biglock do ```mount -o remount,rw /nix/var/nix/db```
+- currently is running tasklist in detached tmux session
+  - [x] make module with systemd service out of that
+
+## creating a new host
+
+### setting up filesystem
+currently nixos offers no declarative way of setting up filesystems and partitions. that means this has to be done manually for every new host. [to make it as easy as possible we can use this guide to setup an encrypted zfs filesystem](https://openzfs.github.io/openzfs-docs/Getting%20Started/NixOS/Root%20on%20ZFS.html)
+
+*we could create a shell script out of that*
 
 ### deploying configuration
 
-hosts are deployed automatically from master. The [hydra build server](https://hydra.dynamicdiscord.de/jobset/malobeo/infrastructure) will build new commits and on success, hosts will periodically pull those changes.
-Big changes (like updating flake lock) could be commited to the staging branch first. [Hydra builds staging seperate](https://hydra.dynamicdiscord.de/jobset/malobeo/staging), and on success you can merge into master.
+#### local deployment
+``` shell
+nixos-rebuild switch --use-remote-sudo
+```
 
-### deploy fresh host
-if you want to deploy a completly new host refer to [docs](https://docs.malobeo.org/anleitung/create.html)
+#### remote deployment
 
-### testing configuration
+you need the hostname and ip address of the host:
+``` shell
+ nixos-rebuild switch --flake .#<hostname> --target-host root@<ip_address> --build-host localhost
+```
+
+in this case 'localhost' is used as buildhost which can be usefull if the target host is low systemresources

 ### build a configuration
+
 to build a configuration run the following command (replace ```<hostname>``` with the actual hostname):
 
 ``` shell
 nix build .#nixosConfigurations.<hostname>.config.system.build.toplevel
 ```
 
+### building raspberry image
+
+for the raspberry it is possible to build the whole configuration as an sd-card image which then can be flashed directly. more information about building arm on nixos can be found [here](https://nixos.wiki/wiki/NixOS_on_ARM).
+
+to be able to build the image you need to enable qemu emulation on the machine you are building with. therefore it is necessary to add the following to your configuration.nix:
+
+``` nix
+boot.binfmt.emulatedSystems = [ "aarch64-linux" ];
+```
+
+then you can build the image with:
+
+``` shell
+nix build .#nixosConfigurations.rpi1_base_image.config.system.build.sdImage
+```
+
+### run a configuration as vm
+
+to run a vm we have to build it first using the following command (replace ```<hostname>``` with the actual hostname):
+
+``` shell
+nix build .#nixosConfigurations.<hostname>.config.system.build.vm
+```
+
+afterwards run the following command to start the vm:
+
+``` shell
+./result/bin/run-<hostname>-vm
+```
+
 ### documentation
 
-documentation is automatically build from master and can be found here: docs.malobeo.org  
-locally you can run documentation using ```nix run .#docs``` or ```nix run .#docsDev```
+for documentation we currently just use README.md files.
+
+the devshell provides the python package ['grip'](https://github.com/joeyespo/grip) which can be used to preview different README.md files in the browser.
+the usage is simple, just run ```grip``` in the same folder as the README.md you wanna preview. then open your browser at ```http://localhost:6419 ```.

-# Create host with nixos-anywhere
-We use a nixos-anywhere wrapper script to deploy new hosts.
-The wrapper script takes care of copying persistent host keys before calling nixos-anywhere.

-To accomplish that boot the host from a nixos image and setup a root password.
+# Create host with disko-install
+How to use disko-install is described here: https://github.com/nix-community/disko/blob/master/docs/disko-install.md
