# Deployment

Beide failen bei Activation des neuen Profils. (TODO)


## Mit NixOps

The official way for deployment is through `deployer.serv.zentralwerk.org`

### Deploy changes

Use deployer system:

```shell
ssh k-ot@172.20.73.9
cd nix-config/
nixops deploy -d hq --check --include=[hostname]
```



### Creating new Container

This does not work yet, as the nixos-system-x86_64-linux.tar.xz image is broken.

1. log into any proxmox server
2. pct create [num] cephfs-iso:vztmpl/nixos-system-x86_64-linux.tar.xz -ostype unmanaged -net0 name=eth0,bridge=vmbr0,tag=[vlantag] -storage vms -hostname [hostname]
3. adjustments through ui if necessary
4. Adjust hq.nixops, add  [hostname]
5. Run
    ```shell
    ssh k-ot@172.20.73.16
    cd nix-config/
    nixops deploy -d hq --check --include=[hostname]
    ```

## Mit `nixos-switch rebuild`

```shell
nixos-rebuild switch -I nixos-config=./hosts/containers/$HOST/configuration.nix --target-host "root@$HOST.hq.c3d2.de"
```


# Secrets

Add your gpg-id to the .gpg-id file in secrets and let somebody reencrypt it for you.
Maybe this works for you, maybe not. I did it somehow:

```
PASSWORD_STORE_DIR=`pwd` tr '\n' ' ' < .gpg-id | xargs -I{} pass init {}
```

Your gpg key has to have the Authenticate flag set. If not update it and push it to a keyserver and wait.
This is necessary, so you can login to any machine with your gpg key.

# Laptops / Desktops

This repository contains a NixOS module that can be used with personal machines 
as well. This module appends `/etc/ssh/ssh_known_hosts` with the host keys of 
registered HQ hosts, and optionally appends `/etc/hosts` with static IPv6 
addresses local to HQ. Simply import the `lib` directory to use the module. As 
an example:

```nix
# /etc/nixos/configuration.nix
{ config, pkgs, lib, ... }:
let
  c3d2Config =
    builtins.fetchGit { url = "https://gitea.c3d2.de/C3D2/nix-config.git"; };
in {
  imports = [
    # ...
    "${c3d2Config}/lib"
  ];

  c3d2 = {
    isInHq = false; # not in HQ, this is the default.
    mapHqHosts = true; # Make entries in /etc/hosts for *.hq internal addresses.
    enableMotd = true; # Set the login shell message to the <<</>> logo.
  };

  # ...
}

```
