Three things that needed a rebuild and a redeploy, or had no way in at all, now have a Site identity panel in the admin: the restaurant's name and tagline, an SVG icon upload, and a switch for whether a menu says when it was published. They live in data/site.json and data/brand/icon.svg, extending ADR 0007: what the owner changes is content, and the config is the seed plus the theme, which still needs a rebuild. An uploaded SVG is a document that would run with this origin's authority, so it is reduced to shapes on the way in and served with default-src 'none'. The archive list keeps its dates even when the switch is off, because those dates are how one old menu is told from another. Also fixes the live check's own trap: the app caches identity in memory, so the tests drive it through the app rather than a second store instance, which would be a second writer.

# Operating the menus
|
|
|
|
For whoever is on the other end of "the menu is wrong". The design is in
|
|
`plan.md`, the vocabulary in `CONTEXT.md`, and the deployment in
|
|
`ansible-playbooks/menu-admin/readme.md`.
|
|
|
|
## Where things are
|
|
|
|
| Thing | Where |
|
|
| --- | --- |
|
|
| The app | container `menu-app.<site>` on `monoco`, image `registry.tanshu.com/menu-admin:<tag>` |
|
|
| Menu content | `/var/lib/menu-app.<site>/data` — `originals/`, `drafts/`, `published/` |
|
|
| Admin | `https://<vhost>/admin` |
|
|
| The password | `/var/lib/menu-app.<site>/site.env` (mode 600, never in git) |
|
|
| Categories | `data/sections.json`, edited in the admin |
|
|
| Brand and theme | `config/<site>.site.json` in this repo, baked into the image (the palette follows the Stitch system in `docs/design/stitch/`) |
|
|
|
|
## Everyday tasks
|
|
|
|
**Publish a new menu.** Sign in at `/admin`, find the Section, fill in "New Menu
|
|
Set" (label, optional valid-until date), Create Draft, then drop the photos in.
|
|
Drag to reorder — the order in the editor is the order customers see. Press
|
|
Preview to check it, then Publish. Publishing archives whatever was current.
|
|
|
|
**Put an older menu back.** Open the Section's "older menus" fold in the admin,
|
|
open the set you want and press "Make current". Its URL does not change.
|
|
|
|
**Change the admin password.** On the server:
|
|
|
|
```sh
|
|
bash /tmp/provision-site-env.sh /var/lib/menu-app.hopsngrains.com --force
|
|
docker restart menu-app.hopsngrains.com
|
|
```
|
|
|
|
**Add, rename, reorder or remove a category.** In the admin, open the
|
|
**Categories** fold at the bottom of the dashboard. A new category starts empty,
|
|
so customers do not see it until you publish a menu into it. Reordering there is
|
|
the order customers see. Two rules: a category's web address is fixed when it is
|
|
created (rename the name as often as you like — a printed QR code keeps working),
|
|
and a category can only be removed once it holds no menus.
|
|
|
|
**Change the restaurant's name or tagline, the icon, or the published dates.** In
|
|
the admin, open the **Site identity** fold: the name and tagline customers see,
|
|
a checkbox for whether a menu says when it was published, and an SVG upload for
|
|
the icon (under 256 KB; the upload replaces the bundled mark and "Remove the
|
|
uploaded icon" brings it back). None of this changes your web addresses.
|
|
|
|
**Change the colours.** Those are still `config/<site>.site.json`, so they need a
|
|
rebuild and push (`./deploy.sh <tag>`) and the playbook with the new tag.
|
|
|
|
**Fix a missing image.** If a Page's thumbnail or viewing image is lost while its
|
|
Original survives, the app can rebuild them:
|
|
|
|
```sh
|
|
docker run --rm --user 1000:1000 -e MENU_ROOT=/data \
|
|
-e MENU_SITE_CONFIG=/app/config/hopsngrains.site.json \
|
|
-v /var/lib/menu-app.hopsngrains.com:/data \
|
|
--entrypoint node registry.tanshu.com/menu-admin:<tag> src/cli/repair.ts
|
|
```
|
|
|
|
`src/cli/verify.ts` does the same inventory without changing anything, and is
|
|
what the server refuses to boot on.
|
|
|
|
## When something looks wrong
|
|
|
|
| Symptom | Look here |
|
|
| --- | --- |
|
|
| Landing page says the menus are being updated | no Section has a Current Menu Set — publish one in the admin |
|
|
| A Section 404s | that Section has no Current set, or the URL is misspelled |
|
|
| Sign-in rejects the right password | `docker logs menu-app.<site>`, then check `site.env` exists and is owned by the app user |
|
|
| Admin is missing entirely | `site.env` was unreadable at boot, so the admin is disabled: run the provision script and `docker restart` |
|
|
| A photo uploads but looks wrong | the browser shrinks to 3000px before upload; that is expected, and the Original is kept |
|
|
| The container will not start | `docker logs` — a fatal integrity problem makes it refuse to serve a data directory it cannot trust |
|
|
| Caddy reload failed during a deploy | nothing is down: Caddy validates before applying. Read the error in the playbook output |
|
|
| Everything is slow | check the tag is current; a Viewing image is ~1600px, so a Section page should not be megabytes |
|
|
|
|
**Logs.** `docker logs -f menu-app.<site>` — JSON lines, one per event, including
|
|
every upload, publish, restore and failed sign-in.
|
|
|
|
**Checking from outside.** No sign-in, no writes, exits non-zero on failure, so
|
|
it can gate a cutover:
|
|
|
|
```sh
|
|
npm run check-site -- https://menu.hopsngrains.com
|
|
```
|
|
|
|
## Backups
|
|
|
|
The app is the only writer. The irreplaceable part is
|
|
`/var/lib/menu-app.<site>/data/originals` — the photos exactly as uploaded, from
|
|
which everything else can be regenerated with `repair`. Back that directory up;
|
|
`site.env` is worth keeping too (otherwise you re-provision the password).
|
|
|
|
## Rolling back
|
|
|
|
The old nginx Site is kept, not deleted. To go back:
|
|
|
|
```sh
|
|
docker start nginx-menu.hopsngrains.com
|
|
```
|
|
|
|
then point Caddy back at it — the cutover section of the playbook readme has the
|
|
exact invocation, including the flag that stops the app's snippet from being
|
|
re-added.
