SSH is not reachable from the open internet. Instead, SSH Port 22 is protected by a wireguard VPN network. Thus, to get root access on the servers, at least two pieces of information have to be added to the admins config:
1. **SSH Public key**: self-explanatory. Add your public key to your user attrset under `sshPubKeys`.
2. **Wireguard device**: each wireguard device has two parts: the public key and the IP addresses it should have in the wireguard network. The pub.solar wireguard network is spaced under `10.7.6.0/24` and `fd00:fae:fae:fae:fae::/80`. To add your device, it's best to choose a free number between 200 and 255 and use that in both the ipv4 and ipv6 ranges: `10.7.6.<ip-address>/32` `fd00:fae:fae:fae:fae:<ip-address>::/96`. For more information on how to generate keypairs, see [the NixOS Wireguard docs](https://nixos.wiki/wiki/WireGuard#Generate_keypair).

One can access our hosts using this domain scheme:
```
ssh barkeeper@<hostname>.wg.pub.solar
ssh <unix-username>@<hostname>.wg.pub.solar
```
So, for example for `nachtigall`:
```
ssh barkeeper@nachtigall.wg.pub.solar
ssh teutat3s@nachtigall.wg.pub.solar
```

To deploy, make sure you have a [working development shell](./development-shell.md).
Then, run `deploy-rs` with the hostname of the server you want to deploy:
### Dry-run
Use `--dry-activate` to show a diff of updated packages and all services that
would be restarted by the update. This will also put all files in place without
switching to the new generation, enabling a quick switch to the new config at a
later moment.
For nachtigall.pub.solar:
```
deploy --targets '.#nachtigall' --magic-rollback false --auto-rollback false --keep-result --result-path ./results
deploy --targets '.#nachtigall' --ssh-user <unix-username> --magic-rollback false --auto-rollback false --keep-result --result-path ./results --dry-activate
```
After reviewing the changes, apply the update with:
```
deploy --targets '.#nachtigall' --ssh-user <unix-username> --magic-rollback false --auto-rollback false --keep-result --result-path ./results
```
For metronom.pub.solar (aarch64-linux):
```
deploy --targets '.#metronom' --magic-rollback false --auto-rollback false --keep-result --result-path ./results --remote-build
deploy --targets '.#metronom' --ssh-user <unix-username> --magic-rollback false --auto-rollback false --keep-result --result-path ./results --remote-build

To skip flake checks, e.g. because you already ran them manually before
deployment, add the flag `--skip-checks` at the end of the command.
`--dry-activate` can be used to only put all files in place without switching,
to enable switching to the new config quickly at a later moment.
We use `--keep-result --result-path ./results` to keep the last `result`
symlink of each `deploy` from being garbage collected. That way, we keep builds
cached in the Nix store. This is optional and both flags can be removed if disk
