cproudlock 417f8a3dd4 Keep a site's own files when its container is replaced
`db_data` was a volume and the instance directory was not, so the documented
update path - `docker compose build api && up -d api` - recreated the container
and discarded everything the site had written. `plugins.json` is only the loud
part: maps, branding, model and application images, employee photos, warranty
proofs, slides, printed-part files and the Dell OAuth token all live under
instance_path too. MySQL rows survive and point at files that are gone, so the
second symptom is images 404ing rather than an error anybody sees.

Reported by an adopting site, which read it as having updated too fast. It had
not; nothing it could have done differently would have kept those files.

DEPLOY.md had been telling sites to back up `instance/` since it was written.
The template never gave them anything to back up.

The air-gap `migrate` service mounts the volume too, because
`flask plugin upgrade-all` rewrites plugins.json and that service exits
immediately after.

The image now creates instance/ ITSELF, owned by the app user. Docker seeds an
empty named volume from image content at the mountpoint, ownership included;
with no such directory in the image the mountpoint is created root-owned 0755
and the container, which runs as shopdb, cannot write into its own instance
directory. Caught by running the built image rather than by reading it: the
volume mounted clean and `touch` came back Permission denied. Verified fixed the
same way.

A stack that predates the volume needs its files moved across ONCE, while the
old container still exists - the volume is seeded from image content, and the
image ships instance/ empty, so it comes up empty rather than inheriting the old
container's writable layer. DEPLOY.md carries the procedure, including the chown
after `docker compose cp`, which writes files under the copying user's numeric
uid rather than the app user's.

Also here, found while checking what an upgrade actually runs: the connected
update steps ran `flask db upgrade` and stopped. Per-plugin Alembic chains
(ADR-008) are not part of that, so a connected site taking an image with a
bumped plugin migration ran the core chain and silently skipped every plugin
chain. The air-gap stack had it right all along. Both commands are in Step 9
now, plus a `db current` check against `db heads`.

Per-Site Deployment Runbook

shopdb-flask is single-tenant per ADR-004. Each adopting facility runs its own stack: own DB, own users, own enabled plugins, own secrets. This document is the runbook for a fresh site deploy.

Prerequisites

  • Docker 24+ and Docker Compose v2 (or equivalent container runtime)
  • A reverse proxy with TLS termination (nginx, traefik, Caddy, GE corporate LB) -- the framework does not terminate TLS itself
  • A MySQL backup destination (offsite recommended)
  • Access to the internal GE Aerospace git server, or a clone of the repo

Step 1: Clone and configure

git clone <internal-git-server>/ge-aerospace/shopdb-flask.git
cd shopdb-flask
cp .env.example .env

Edit .env:

Variable Required Notes
FLASK_ENV Yes production for live sites
SECRET_KEY Yes python -c "import secrets; print(secrets.token_urlsafe(64))"
JWT_SECRET_KEY Yes Same generation, different value
DATABASE_URL Yes mysql+pymysql://shopdb:PASSWORD@db:3306/shopdb_flask (matches docker-compose)
CORS_ORIGINS Yes Comma-separated explicit origins. Wildcard rejected.
MYSQL_ROOT_PASSWORD Yes Container only
MYSQL_PASSWORD Yes Container only, must match DATABASE_URL password
MYSQL_PORT No Default 3306
API_PORT No Default 5001
LOG_LEVEL No Default INFO
ZABBIX_URL, ZABBIX_TOKEN No Only if printers plugin uses Zabbix
COLLECTOR_API_KEY No Shared key for /api/collector/* ingest. Required only if unattended collectors push data. Endpoint fails closed (denies) when unset.
COLLECTOR_API_KEY_<PLUGIN> No Per-plugin override (e.g. COLLECTOR_API_KEY_COMPUTERS), checked before the shared key (ADR-006)
EMPLOYEE_DB_HOST/USER/PASSWORD/NAME No Read-only HR directory for notifications + kiosks. No safe default for the password.

Step 2: Bring up the stack

docker compose build
docker compose up -d

The Docker image builds the Vue frontend in a first stage and copies the compiled SPA into the API image, so docker compose build produces a self-contained image with the UI already built. No separate Node step is needed for a container deploy. (For a bare-metal/venv install instead, build the frontend by hand: cd frontend && npm ci && npm run build, which writes frontend/dist/ for Flask to serve.)

The MySQL container initializes its volume on first run. The API container waits for db to be healthy via healthcheck. Check logs:

docker compose logs -f api

If ProductionConfig.validate() raises, the container exits with the offending env-var named in the log. Fix .env and docker compose up -d again.

Step 3: Initialize the database schema

docker compose exec api flask db upgrade
docker compose exec api flask plugin upgrade-all

flask db upgrade applies the core Alembic chain: the baseline migration plus every later migration, which together create all core AND bundled-plugin tables through the chain head. flask plugin upgrade-all then stamps each bundled plugin's own migration chain (the alembic_version_<plugin> tables) and applies any plugin-specific migrations added after the ownership cutover. Both commands are idempotent, so re-running them is safe. See ADR-008 for why plugin schema splits into per-plugin chains from the cutover forward.

Lean sites (ADR-014): the core chain creates every bundled plugin's tables, so a site that ships only some plugins still has the others' (empty) tables. To carry only core + chosen-plugin tables, prune the rest once, at initial provisioning, after the two commands above:

docker compose exec api flask plugin prune-schema            # dry-run, review
docker compose exec api flask plugin prune-schema --yes --force

It drops the tables of every plugin not installed on this site. --force is needed because the core chain seeds a few plugin reference tables (default access protocols, etc.); at first provisioning those hold only seeded defaults, before any site data. It refuses to drop a table that holds rows without --force, so it is safe to leave out of routine upgrades - run it only when provisioning a lean site or after deliberately removing a plugin. Installing a pruned plugin later recreates its tables automatically.

Charset: the schema is utf8mb4 (utf8mb4_unicode_ci). The docker-compose db service sets --character-set-server=utf8mb4, so the auto-created shopdb_flask database is utf8mb4. If you point at an external MySQL instead of the bundled container, create the database as utf8mb4 first, or it inherits the server default (often latin1) and the schema silently drifts:

CREATE DATABASE shopdb_flask CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci;

DATABASE_URL must keep ?charset=utf8mb4 so the connection matches. On MySQL older than 5.7 also enable innodb_large_prefix=ON + innodb_file_format=Barracuda, or the utf8mb4 indexes exceed the 767-byte prefix limit (error 1071). MySQL 5.7+ and 8.0 need no extra config.

Step 4: Seed permissions, settings, and reference data

Run all three seeders. They are idempotent, so re-running them on an existing database is safe (it adds anything missing and leaves existing rows alone).

docker compose exec api flask seed permissions
docker compose exec api flask seed settings
docker compose exec api flask seed reference-data
  • seed permissions - creates the RBAC permission rows and the default roles the app checks with @require_permission. Run this before anyone logs in or permission checks have nothing to match.
  • seed settings - writes the default Setting rows (branding, ServiceNow integration, floor-map placeholders, search toggles, site identity). A site overrides these later in Settings or the setup wizard.
  • seed reference-data - creates default ModelType, AssetStatus, LocationType, CommunicationType, OperatingSystem, RelationshipType rows seeded with the platform contract values (partof, controls, connectedto). (Vendor, Location, and BusinessUnit are not seeded here; they come from seed demo.)

Step 5: Pick plugins to enable

The image bundles thirteen plugins (computers, employees, geenforce, knowledgebase, machines, measuringtools, network, notifications, printedparts, printers, slides, usb, warranty). Only enabled plugins are loaded.

docker compose exec api flask plugin list
docker compose exec api flask plugin install computers
docker compose exec api flask plugin install machines
# ... repeat for each plugin the site tracks

To install a sister-site or third-party plugin (per ADR-003), drop its directory into <repo>/plugins/<name>/ (the docker-compose mounts this read-only into the container) and run flask plugin install <name>.

Step 6: Create the first admin (setup wizard)

The primary path is the first-run setup wizard. Once the stack is up and the DB is seeded, browse to the site (through the reverse proxy configured in Step 7, or directly at the API port during bring-up) and go to /setup. The wizard creates the first admin account and captures site identity (facility name, optional logo). It runs only while setup_complete is false; after it finishes the route redirects to the app.

Headless alternative (no browser, e.g. automated provisioning):

docker compose exec api flask seed admin --username admin --email admin@facility.example.com
# Password is generated and printed once. Store in your password manager.

Subsequent users are managed through the UI.

Step 7: Front the API with TLS

The Flask container listens on 5001/tcp over plain HTTP. Production exposure must go through a reverse proxy that terminates TLS:

server {
  listen 443 ssl;
  server_name shopdb.facility-a.example.com;

  ssl_certificate     /etc/ssl/certs/shopdb.crt;
  ssl_certificate_key /etc/ssl/private/shopdb.key;

  location / {
    proxy_pass http://localhost:5001;
    proxy_set_header Host              $host;
    proxy_set_header X-Real-IP         $remote_addr;
    proxy_set_header X-Forwarded-For   $proxy_add_x_forwarded_for;
    proxy_set_header X-Forwarded-Proto $scheme;
  }
}

The framework reads X-Forwarded-For for audit logging.

Step 8: Backups

Per-site MySQL backups are the site's responsibility. Recommended: nightly mysqldump to offsite storage with 14-day retention.

docker compose exec -T db mysqldump -u root -p"${MYSQL_ROOT_PASSWORD}" shopdb_flask | gzip > backup-$(date +%F).sql.gz

Verify a restore quarterly. Back up the instance/ directory alongside the DB; it holds uploaded floor plans, branding, plugins.json, and tokens that are not in MySQL. Under compose it is the instance_data named volume:

docker compose run --rm -v "$PWD:/backup" api tar czf /backup/instance-$(date +%F).tar.gz -C /app/instance .

See docs/BACKUP-RESTORE.md for the full backup and restore procedure.

Step 9: Updates

git pull origin main
docker compose build api
docker compose up -d api
docker compose exec api flask db upgrade
docker compose exec api flask plugin upgrade-all
docker compose exec api flask db current   # must match `flask db heads`

plugin upgrade-all runs the per-plugin Alembic chains (ADR-008), which db upgrade does NOT touch. The air-gap stack runs both in its one-shot migrate service; a connected stack has to ask.

up -d api REPLACES the container. Everything the site has written lives in the instance_data volume for exactly this reason: the enabled-plugin list (plugins.json), uploaded floor plans and branding, model and application images, employee photos, warranty proofs, slides, printed-part files, and the Dell OAuth token. If your stack predates that volume, those files are in the old container's writable layer and an update discards them. Move them across ONCE, before the next rebuild:

docker compose cp api:/app/instance ./instance-rescued   # BEFORE pulling new code
docker compose up -d api                                 # creates the volume
docker compose cp ./instance-rescued/. api:/app/instance
docker compose exec -u root api chown -R shopdb:shopdb /app/instance
docker compose restart api

The chown is not optional. docker compose cp writes the files with the copying user's numeric uid, which is only shopdb by coincidence if your host account happens to be uid 1000. Get it wrong and the site reads its restored files fine and cannot write new ones.

Then run the migrations and confirm the plugins came back:

docker compose exec api flask db upgrade
docker compose exec api flask plugin upgrade-all
docker compose exec api flask db current   # must match `flask db heads`
docker compose exec api flask plugin list  # the site's plugins, enabled

Restore instance/ BEFORE plugin upgrade-all: that command works from plugins.json, so running it against an empty instance directory upgrades nothing and reports success.

The symptom of having missed this is a site that comes back with its plugins disabled and image URLs that 404: the MySQL rows survived, the files did not. Re-enabling by hand works, but flask plugin apply-profile <profile.json> puts the same list back in one command and is the thing to keep in version control.

The framework's __contract_version__ may have moved. Check docs/adr/ for any new ADRs since the last update. If an ADR introduces a breaking change, the upgrade may require coordinated work; the ADR's "Consequences" section documents it. See docs/UPGRADE.md for the full upgrade procedure, including re-seeding and the v0.5+ floor-plan note.

Common issues

Symptom Cause Fix
ConfigError: SECRET_KEY is required in production .env missing or blank Set SECRET_KEY in .env, re-up
ConfigError: CORS_ORIGINS must be a comma-separated allowlist .env has * Set explicit origins
PluginVersionError: requires core_version X but framework is Y Plugin pinned a too-narrow range Update manifest.json core_version or pin framework version
500s after flask db upgrade Migration ran but app cached old schema docker compose restart api
Cannot reach API after restart Reverse proxy not pointing at the container's exposed port Confirm API_PORT and proxy config

Health check

curl -s -X POST -H "Content-Type: application/json" \
  -d '{}' http://localhost:5001/api/auth/login \
  | jq .
# Expect: {"status": "error", "data": {"error": {"code": "VALIDATION_ERROR", ...}}}

If this returns a 500 or no JSON, the container is unhealthy. Check docker compose logs api.
