# Installing as a Rune

verdande ships with a Rune manifest for
[Yggdrasil Panel](https://github.com/kristianwind/yggdrasil).

## If the image will not pull

```
create container: Error response from daemon:
No such image: ghcr.io/kristianwind/verdande:latest
```

This message is a liar. It does not mean the tag is missing from the registry —
it means the image is not on the host, and the panel's attempt to fetch it failed
without saying so.

The usual cause is a **private** GHCR package. Yggdrasil pulls anonymously: its
`PullImage` calls the Docker SDK with no `RegistryAuth`, so a private image comes
back 401. The pull error is discarded, and `ContainerCreate` — which only ever
looks locally — then reports the image as missing.

!!! warning "`docker login` on the host does not help"
    `docker login` is client-side. The daemon stores no credentials; the CLI
    sends them itself with each request. Yggdrasil is a different client and
    sends none, so logging in changes nothing for the panel.

**Make the package public.** Under
[Packages → verdande → Package settings](https://github.com/users/kristianwind/packages/container/package/verdande)
→ *Change visibility*. The repository stays private; only the built image becomes
readable, which is what the manifest and these pages have always assumed.

To keep it private you have to put the image on the host yourself, before
creating the server, and again after every release:

```bash
echo "$GHCR_TOKEN" | docker login ghcr.io -u kristianwind --password-stdin
docker pull ghcr.io/kristianwind/verdande:latest
```

`GHCR_TOKEN` is a GitHub token with the `read:packages` scope. The panel's own
pull still fails silently; it simply finds the image already there.

## Installing

1. **Runes → Carve a rune (upload)** and pick
   [`rune/verdande.yaml`](https://github.com/kristianwind/verdande/blob/main/rune/verdande.yaml)
   from the repository.
2. Create a server from it.
3. Fill in the settings below.
4. Start it, open the URL, create the first account.

## Settings

| Setting | What to put |
|---|---|
| **Public address** | The address you reach it on. `{{PUBLIC_URL}}` is the default and usually right. |
| **SMTP host** | Your mail server. Leave blank and invite links are shown in the app instead of emailed. |
| **SMTP port** | 587 for STARTTLS, 465 for implicit TLS. |
| **SMTP username / password** | As your mail server expects. |
| **Sender address** | What invites and reminders come from. |
| **Use STARTTLS** | On, unless you are on port 465. |
| **How long a login lasts** | `720h` — thirty days. |

!!! note "Why the public address cannot be guessed"
    The host port is not chosen until the server is created, so verdande has no way
    to work out its own address. The panel does, and passes it in as
    `{{PUBLIC_URL}}`.

## Reaching it from outside

Give the server a **Subdomain** under its settings and enable
**Cloudflare Tunnel (subdomains)** under **Settings → Network**. No port forwarding
and no public IP.

## Backups

The Rune's backup includes the whole `/data` directory, which is what you want —
see [the warning about copying the database alone](self-hosting.md#what-lives-in-data).

## Watchers

The manifest ships log watchers for database errors, repeated failed logins and
HTTP 5xx. They appear under **Settings → Kvasir Watchers** as ordinary per-server
rules you can edit or turn off.
