menu-admin was the odd one out: it built from the working directory with a date
tag and a multi-arch manifest, deployed with `-e tag=`, and kept the Docker-era
container name. The other two apps build from `git archive HEAD` and tag with the
commit, so what runs on the host is exactly what git knows about; build only for
the architecture emily actually runs; and use one slug for the container, its
network and its data directory.
The build is now their three lines: `podman build --platform linux/arm64` from
`git archive HEAD`, tagged `:<commit>` and `:latest`, pushed with `podman push`
rather than a manifest. `deploy.sh` pushes the commit first, then refuses a dirty
tracked tree or a HEAD that is not origin/main — which is what makes the commit
tag trustworthy — takes the same `--force` and `--no-push`, and ends in the same
`-u tanshu ... -e image_tag=<commit>`. Its own lint/typecheck/test gate stays,
but behind `--checks`, so a plain deploy behaves as theirs does.
The registry credential moves into vars/default.yml and the role logs in, pulls
and logs out around it, as their roles do. The image is only pulled at deploy
time, so the unit keeps podman's default `Pull=missing` and a reboot never needs
the registry. This is the same plaintext credential the other two repos carry.
One real bug goes with it: the healthcheck gate ran before the handler that
restarts a changed unit, so a run that only changed the unit checked the stale
container. `meta: flush_handlers` before the gate is the fix the sibling repos
already made.
The container, network and data directory are all menu-<site> now. The dotted
Docker-era name and the NetworkAlias it needed are gone, so `podman logs
menu-<site>` and `systemctl --user status menu-<site>` are the same two commands
across all three apps. The Dockerfile keeps its name for the same reason: podman
reads it as readily as a Containerfile, and the siblings use that name too.
The fleet on emily is rootless Podman with Quadlet units under
~/.config/containers/systemd and state in ~/podman-data, all behind one shared
Caddy unit. This brings the menus in line instead of leaving them the last
Docker deployment. The build moves with them: podman reads a Containerfile as
readily as a Dockerfile, so the name now says which toolchain is real.
The app is one .container and one .network file. Two details carry it.
UserNS=keep-id maps the image's own node account onto the user that owns the
units, so data/ and site.env stay owned by tanshu: plain tar backups, no
subuids. provision-site-env.sh writes site.env with the same mapping rather
than --user, which under rootless Podman would have produced a subuid-owned
file the app could not read. And the Site registers its own network with Caddy
by writing a drop-in beside caddy.container, so Caddy never lists its upstreams
and never changes when a Site is added. The unit keeps the Docker-era container
name for the scripts and muscle memory that look it up, while the Caddyfile
proxies to a dotless NetworkAlias, because a container name with dots in it is
a liability in DNS.
The unit keeps podman's Pull=missing, so a restart or a reboot never depends on
the registry being reachable, while the play pulls explicitly at deploy time.
That is also where a missing `podman login` for the private registry now fails,
with the instruction, rather than as a unit that will not start.
copy-site-data.sh moves a Site's data across, and is not a plain rsync:
/var/lib/menu.* on monoco belongs to uid 1000 while the ssh user there is 1001,
so the read needs sudo; monoco cannot ssh to emily, so the workstation relays
the tar; and the extraction runs as tanshu on emily, which is what makes the
files land owned by the user keep-id maps the app onto. It proves the copy by
comparing a SHA-256 of the whole tree against the source and checking every
file's owner.
Not yet done: the copies themselves and the DNS move, which need a human.
The deploy failed on hngmohali with 'all predefined address pools have been
fully subnetted': every 172.17-172.30/16 is in use, 172.31/16 is the host's own
VPC so Docker will not allocate from it, and all sixteen 192.168.0-240/20 blocks
are taken. Docker therefore refuses a network created without a subnet.
Each Site now names a free network_subnet (10.210.0.0/16, one /24 each), the role
looks the network up first and only creates it when it is absent and with that
subnet, and it fails with an explanation when a Site declares none. Existing
networks are left alone, because Docker cannot change a subnet in place and the
Sites already running have theirs. The test checks every Site declares one, and
the deployment readme says a new Site needs a free subnet.
deploy.sh now deploys every Site by default, with SITE=<name> to narrow it, which
is what the local edit was reaching for.
ESLint cannot parse this project's TypeScript: typescript@7 is the native port
with no JavaScript compiler API, which every ESLint TypeScript parser needs, and
typescript-eslint refuses to install with a >=4.8.4 <6.1.0 peer. oxlint parses
TypeScript without the compiler API, so it lints the .ts and the .js together in
about 20ms over the whole repo, and it runs the correctness category as errors.
It found one real thing on the first run: the drag harness built its fetch
options with a body key even for GET. The four opinionated rules it also flagged
are off with their reasoning in the README, since oxlint's config takes no
comments. lint is back in deploy.sh's checks, and the editor has lint tasks and
the oxc extension recommendation. Prettier is unchanged.
The playbook, its roles, its vars and a new inventory now live in ansible/,
beside the app they deploy, the way the other apps on this machine are laid out.
The inventory follows the same shape: one entry per Site, all on the same box,
each naming its own vars file through var_file, so adding a Site is one line and
a file rather than a command-line flag. ansible_host is written as the
resolvable name rather than an ssh alias so the inventory works on any machine.
The image is now built with podman as a multi-arch manifest and pushed to
registry.tanshu.com/menu-admin, mirroring the Makefile used elsewhere on this
machine: build-production, plus build-check and build-check-local for a build
that does not push. deploy.sh runs the checks, builds, pushes, then runs the
playbook for the Site named by SITE, with SKIP_DEPLOY for a push without a
deploy.
ESLint comes out again: this project's typescript@7 has no JavaScript compiler
API, so typescript-eslint cannot install, and linting only the JavaScript was
not worth keeping. Prettier stays, and the README records why ESLint is absent
and what would bring it back.
Prettier owns formatting: .prettierrc.json, format and format:check scripts, and
a one-off pass over the repo so the check is green from the start. Embedded
language formatting is off deliberately - the renderers build HTML in html
tagged templates and letting Prettier reflow those would change the markup
customers receive. docs/ is excluded because it is hand-wrapped prose, and shell
scripts have no Prettier parser.
ESLint covers the JavaScript: the two browser scripts, the build and check
scripts, and its own config. no-var is scoped out for the browser scripts on
purpose; they are plain ES5-shaped IIFEs and a hoisting difference would only
show up in a browser.
ESLint cannot lint the TypeScript here: typescript@7 is the native port with no
JavaScript compiler API, and typescript-eslint requires a 4.8-6.1 peer, so it
refuses to install and forcing it through would leave a parser that cannot read
the compiler. tsc --noEmit stays the TypeScript gate; README records the two
ways to change that.
lint and format:check now run in deploy.sh, and VS Code formats on save with
Prettier and surfaces ESLint findings.
The playbook pulls the tag from the registry, creates the data root owned by the
app user, runs the container with its config baked into the image, waits for
health, then verifies the data directory as the app user so a permissions
mistake surfaces at deploy time. Caddy is pointed at the app with a stable
marker, so a temporary hostname can be checked beside the live site and the
cutover is one invocation with the retire flags set.
