tanshu f2d8058456 Deploy in one run, with nothing older to preserve
There is no previous system kept serving, so the playbook no longer knows about
one: the retire flags, the temporary web address, the task that removed the old
nginx snippet and the task that stopped the old container are gone. One run
starts the container and points the Site's web address at it, and deploying an
earlier tag is the rollback. The vars lose vhost, retire_nginx_snippet,
retire_nginx_container and legacy_container; the Caddy role keeps only the
snippet upsert.

The deployment readme drops its staged-rollout sections and the glossary of words
that no longer exist, and the plan's sequence and the operating notes describe
the single run instead.

The menu deployment

Lives here, beside the app it deploys. One run deploys a Site: it starts the app's container and points the Site's web address at it. There is no older system to keep serving, so there is no staged rollout and nothing to retire — deploying an earlier tag is the rollback.

What lives where

Thing Where
Name, tagline, icon, categories, menus on the server under /var/lib/menu-app.<site>/data — the admin edits them
Theme colours config/<site>.site.json in the repo, baked into the image
Admin password hash, session secret /var/lib/menu-app.<site>/site.env (untracked, mode 600)
Which image tag runs -e tag=<tag>
Which Site is deployed the inventory entry in hosts
The web address it serves host: in vars/<site>.yml

Deploying

From the repo root:

./deploy.sh 2026-09-22                 # checks, podman build+push, then deploys
SKIP_DEPLOY=1 ./deploy.sh 2026-09-22   # build and push only

deploy.sh runs make build-production TAG=<tag>, which builds a multi-arch podman manifest (linux/amd64,linux/arm64) and pushes latest and the tag to registry.tanshu.com/menu-admin. Then it runs this playbook against the Site named by SITE (default hopsngrains).

By hand:

make build-production TAG=2026-09-22
cd ansible
ansible-playbook --inventory=hosts playbook.yml --limit hopsngrains -e tag=2026-09-22

Every Site runs on the same box, so hosts has one entry per Site pointing at the same ansible_host with its own var_file. ansible_host is written as the resolvable name rather than an ssh alias, so the inventory works whatever a machine's ~/.ssh/config says. (ssh on some machines complains about /etc/ssh/ssh_config.d/20-systemd-ssh-proxy.conf being owned by nobody; that is a local file-permission bug whose fix is sudo chown -R root:root /etc/ssh/ssh_config.d, not something this playbook works around.)

Adding a Site is one line in hosts and a copy of vars/hopsngrains.yml.

Checking it landed

npm run check-site -- https://menu.hopsngrains.com

Read-only, exits non-zero on failure. Then from a phone: the landing page, a Section page, the page counter, tap-to-zoom, and signing into /admin to publish something.

The admin password

The app starts with the admin disabled while /var/lib/menu-app.<site>/site.env is missing, and the playbook says so rather than failing. Create it once per Site:

scp scripts/provision-site-env.sh monoco:/tmp/
ssh monoco bash /tmp/provision-site-env.sh /var/lib/menu-app.hopsngrains.com
ssh monoco docker restart menu-app.hopsngrains.com

Rolling back

Deploy the previous tag:

./deploy.sh <previous-tag>

docker logs menu-app.<site> is where a failed container says why.
