Kristian WindandClaude Opus 5 d7e250f860 docs(rune): a rune does not update itself, and the server need not be deleted
Two corrections after checking against Yggdrasil's own behaviour rather
than guessing at it.

The advice to delete the failed server and make another was wrong. The
image reference is read from the rune at container-create time, and both
Start and Restart recreate the container — so once the image can be
fetched, pressing Start on the server you already have is enough.

And a rune does not pick up a changed manifest on its own. The panel
writes the rune row from a UI action only; neither a restart nor a timer
does it. So a new manifest needs Runes → verdande → Update, and the
catalogue list is cached in memory for ten minutes, which is long enough
that two attempts in a row can both hand back the old version.

The host-pull fallback now says what it costs: the panel re-pulls on
every recreate, fails quietly, and carries on with the local image, so a
new release looks like it rolled out when it did not. It is a stopgap for
keeping the package private, not a way to run this.

Installing as a Rune

verdande ships with a Rune manifest for Yggdrasil Panel.

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 → Change visibility. The repository stays private; only the built image becomes readable, which is what the manifest and these pages have always assumed.

Once it is public, press Start on the server you already have. There is no need to delete it and make another: the image reference is read from the rune at container-create time, and both Start and Restart recreate the container.

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

sudo docker login ghcr.io -u kristianwind
sudo docker pull ghcr.io/kristianwind/verdande:latest

Run it as the user the Docker daemon runs as — sudo if the panel does. The panel's own pull still fails silently; create simply finds the image already there.

!!! danger "This hides updates" The panel re-pulls on every recreate, fails quietly, and carries on with the local image. A new release then looks like it rolled out and did not. For something you intend to update, public is the right answer and host-pull is the stopgap.

Installing

  1. Runes → Carve a rune (upload) and pick 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.

!!! note "Updating the rune is a manual step" A rune does not update itself when this manifest changes. The panel writes the rune row from a UI action only — neither a restart nor a timer does it — so pick up a new manifest with Runes → verdande → Update, or install it again from Browse GitHub.

The catalogue list is cached in memory for ten minutes, so two attempts in a
row can both hand you the old version. Recent panel versions show the list's
age with a *fetch again* link.

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.

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.
