## SSH config:

You will need to set your admin username if it doesn't match your local username.

```
Host *.nix-community.org
  User <youradminusername>
```

## Deployment commands:

```console
$ ./inv deploy
```

If you want to reboot a machine, use the following command:

```console
$ inv deploy --hosts build02 reboot --hosts build02
```

## Install/Fix system from Hetzner recovery mode

1. Copy your ssh key to the recovery system so that the kexec image can re-use it.

```console
yourmachine> ssh-copy-id root@build0X.nix-community.org
```

2. Download and boot into kexec-image:

```console
$ curl -L https://github.com/nix-community/nixos-images/releases/download/nixos-unstable/nixos-kexec-installer-x86_64-linux.tar.gz | tar -xzf- -C /root
$ /root/kexec/run
```

### Debug VM

You can start a vm from the rescue system in order to debug the boot:

```console
$ nix-shell -p qemu_kvm --run 'qemu-kvm -m 10G -hda /dev/sda -hdb /dev/sdb -curses -cpu host -enable-kvm'
```
