Two NAS realities, both hit on a real Synology box.
- "NanoCPUs" error part-way through the project build: `cpus:` maps to the
NanoCPUs field, which DSM's Docker daemon rejects. Removed from all three
services (and from .env.prod.example). mem_limit uses the much older Memory
field and works, so memory caps remain the throttle. Noted in the header
next to the other DSM constraints.
- `docker compose build` on DSM: "'compose' is not a docker command". DSM and
QTS ship the standalone `docker-compose` binary with no plugin subcommand,
so every one of the script's 21 compose invocations was wrong for the target
platform. The script now detects which is present, and only passes `--wait`
when it finds v2 — on v1 it falls back to the health_gate it already had,
which is also now run after `up` on both paths.
That the build reached container creation before failing says their compose
parses the rest of the file (anchors, profiles, service_completed_successfully,
top-level name), so this was a daemon-level rejection, not a schema one.

Synology Container Manager rejects the compose file with "Property include is
not allowed": DSM bundles an older Compose than the one that introduced
`include:` (v2.20). The root docker-compose.yml existed purely so the NAS GUIs
would find production rather than the dev service stack, so using a feature
the GUI cannot parse defeated its only purpose.
docker/docker-compose.prod.yml is now the root docker-compose.yml itself — one
plain, flat file, no indirection. Build contexts go from `..` to `.`, the
backup sidecar mounts ./docker/backup.sh, and webmail.sh points at the new
path. Nothing else changed: same services, same project name webmail-prod,
same guards.
The header now says why the file lives at the root and to keep it free of
newer compose features, so this does not get "tidied up" back into something
DSM refuses.
Verified with `docker compose up -d --wait` from the repo root as the GUI
invokes it: all services healthy, account created, backup sidecar resolving
its script at the new path, and webmail.sh status/doctor/down driving the same
stack.

Synology Container Manager and QNAP Container Station build a project from a
folder and look for `docker-compose.yml` in it. Pointing either at `docker/`
finds the DEV service stack and starts the wrong thing, so production now has
a root-level entry point.
- docker-compose.yml at the repo root: `include`s the prod stack (relative
paths resolve against the included file's directory, so the build context
and backup.sh still resolve) and pins `name: webmail-prod`. A project name
typed into the GUI overrides the file's, so the docs say to type the same
one.
- webmail.sh init now drops a `.env` symlink to docker/.env.prod in the repo
root: the GUI reads `.env` from the project folder, and a symlink keeps one
file to edit instead of two copies that drift.
- Required-variable guards on DATA_ROOT / MASTER_KEY / POSTGRES_PASSWORD /
APP_DOMAIN. A bare `docker compose up` with no env file used to interpolate
DATA_ROOT to "" and bind-mount /postgres at the root of the filesystem; it
now aborts with a message naming the variable.
- require_env no longer sources the env file. Sourcing executed it as shell:
ENABLED_PLUGINS=calendar contacts labels filters ran `contacts` as a command
and broke every subcommand, and anything else in the file that holds the
master key would have been executed too. Replaced with a compose-compatible
KEY=VALUE parser; the template quotes the value as well.
- doctor: no longer aborts on a not-yet-created DATA_ROOT (set -e + pipefail
killed it inside a `df` assignment — on exactly the pre-install run where
its NFS/SMB check is the one that matters), and probes the nearest existing
ancestor so that check works before the directory exists.
- docs §2.5 rewritten with what the GUI can and cannot do: no compose
profiles (so no Meilisearch), no health-gated update, no restore; plus the
Task Scheduler route for generating MASTER_KEY without enabling SSH, and
why init/migrate showing "Exited (0)" is correct.
Verified by running `docker compose up -d --wait` from the repo root with no
-f and no --env-file (what the GUI does): all services healthy, migrations
applied, app served, and deploy/webmail.sh manages the same project.

Everything needed to run the app on an Intel NAS that is also doing other
jobs: one published port, no host networking, memory/CPU caps and log
rotation on every container, and all state in bind mounts under DATA_ROOT
so mail survives image updates, project deletion in the NAS UI, and full
reinstalls — and so Hyper Backup/HBS3 can actually see it.
- docker/Dockerfile.backend: multi-stage, non-root (uid 10001), tini for
the <10s graceful lease release. Installs the four plugins as entry-point
distributions. One image, several roles via docker/entrypoint.sh
(api | worker-sync | worker-jobs | migrate | reindex | plugins).
- docker/Dockerfile.frontend + nginx.conf: SPA + /api reverse proxy with
the WebSocket upgrade for /api/ws, and X-Forwarded-Proto preserved so
the API still emits __Host-/Secure cookies when TLS is terminated by
the NAS reverse proxy (identity/cookies.py keys off request scheme).
- docker/docker-compose.prod.yml: project name webmail-prod, NOT webmail —
docker-compose.yml (dev services) owns that name, and two compose files
sharing one project name fight over each other's containers.
Meilisearch is an opt-in profile; SEARCH_BACKEND=pg is the default so a
small NAS pays nothing for search.
- migrate runs as a one-shot (core Alembic head + every plugin branch)
that everything else waits on, so a bad migration can never leave new
code running against an old schema.
- docker/backup.sh: nightly pg_dump verified with `pg_restore --list`
before it counts as a backup, with retention and a baseline on first
start.
- deploy/webmail.sh: init/doctor/up/down/status/logs/update/rollback/
backup/restore/reindex/psql/shell. `update` is backup -> images ->
migrate -> roll workers, api, web -> health-gate, with automatic
rollback to the previous version if the gate fails. `doctor` refuses to
be quiet when DATA_ROOT is on NFS/SMB (silent Postgres corruption).
- deploy/build-push.sh: build images off-NAS (the frontend build wants
~2GB RAM) and push to Gitea, or --save a tar to carry over.
- scripts/reindex_search.py: rebuild the search index from Postgres alone.
Every SearchDoc field is already stored, so the index is derived data
that never needs backing up — this closes the only real objection to
running Meilisearch on a box whose volumes may be wiped.
- pyproject: package-data for accounts/presets.yaml and the shared plugin
Alembic env. Without it a non-editable install (i.e. any image) silently
ships a package that fails at runtime.
- GET /api/version, used by the deploy health gate.
Verified end to end on a real stack: fresh install, all services healthy,
core + 4 plugin migration branches applied, login/SPA/plugin bundles
through nginx, WS upgrade returning 101, __Host- cookies under a
simulated TLS proxy, backup -> restore round-trip preserving user and
plugin schema, failed-update auto-rollback (both a bad migration and a
boot-crashing API), and Meilisearch profile serving a live query.
ruff + mypy --strict clean, 363/363 backend tests pass.
