FabledCurator

Self-hosted media curation — gallery, ML tagging, and subscription-driven downloading in one app. Part of the FabledSword family.

Combines what was ImageRepo (gallery, ML, importer) and GallerySubscriber (gallery-dl wrapper, subscriptions, credential capture) into a single product.

Status

In production. main is continuously deployed — every merge to main builds and publishes :latest images, so whatever is on main is what is running. Day-to-day work happens on dev, which publishes :dev images.

Versions and tags

Three image tags exist, and no others:

Tag	Branch	Meaning
:latest	main	Production. Moves on every merge.
:c-<sha>	main	Immutable — the rollback unit, all three images together.
:dev	dev	The rolling test channel. Moves on every push.

There are deliberately no version tags. Nothing pins one, and a per-build name nobody reads is upkeep for a model FC does not run (family rule 145; the reasoning is note #3127 §5). Rolling back is docker pull …:c-<sha>.

Each artifact still has a version, derived rather than chosen: the commit time of the newest change to that artifact's own shipped files, as YYYY.MM.DD.HHMM UTC (rule 148). Four artifacts, four independent versions — a push touching only agent/ re-versions the agent and leaves web and ml alone, and CI skips the builds whose content did not move.

Because no registry name carries it, the running instance's own report is the only answer to "which build is this?". The foot of Settings shows FabledCurator 2026.08.29.0201 · dev, and /api/health returns the same two fields.

Release tags are optional bookmarks — FC went twelve weeks without one and nothing was wrong. Pushing v<version> publishes a Forgejo release listing the commits since the previous tag; it builds no image.

What's in here

Five deployable pieces, built by .forgejo/workflows/build.yml:

Piece	Built from	Image	Role
Web / workers	Dockerfile	fabledcurator	Quart API + the built Vue SPA in one image. entrypoint.sh picks the role: web, worker, scheduler. The maintenance-long service is a second worker pinned to the long-running maintenance queue.
ML worker	Dockerfile.ml	fabledcurator-ml	Same app, plus requirements-ml.txt — tagging and embedding models that run in-container.
GPU agent	agent/Dockerfile	fabledcurator-agent	Optional desktop-GPU worker (agent/). Leases jobs over HTTP only — never touches the database or Redis. Run it for a burst, stop it to reclaim the card. See agent/README.md.
Firefox extension	extension/	signed XPI	MV3 extension: pushes platform session cookies into FC and adds a creator as a Source in one click. AMO-signed on both dev and main (one signature per extension change, shared by the two channels), bundled into that channel's web image and served from Settings → Maintenance. See extension/README.md.
Data	—	pgvector/pgvector:pg16, redis:7-alpine	Postgres with pgvector for embeddings; Redis as the Celery broker.

Quick start

For local development and testing, just:

docker compose up -d
# UI: http://localhost:8080

That uses sane dev defaults baked into docker-compose.yml and the dev override (docker-compose.override.yml, auto-merged) — local builds, DEBUG logging, exposed Postgres + Redis ports on the host. No .env required.

For a production-like deployment, override the dev defaults via shell env or a .env file (see .env.example for the variable names) and use:

docker compose -f docker-compose.yml up -d
# (skips the dev override, so containers pull published :latest images)

-f is doing real work there: it tells Compose to use only that file, which skips docker-compose.override.yml and its local builds. What you get is the :latest images — the stable channel, built from main. This is the install path, and it is the one to use if you are running FabledCurator rather than working on it.

:dev is the other channel: rebuilt from the dev branch several times a day, bleeding edge, no stability promise. Nothing in this repo points an installer at it, and nothing should.

The GPU agent is deployed separately, on the machine with the card — agent/docker-compose.yml, not this stack.

Deployment posture

FabledCurator is designed to run inside a self-hosted homelab environment over plain HTTP. If you want TLS, terminate it at your reverse proxy. The app does not generate certificates, redirect to HTTPS, or set HSTS.

CI / Forgejo setup

Four workflows: ci.yml (lint, extension-version check, backend unit tests, frontend build, integration), extension.yml (extension lint, vitest, XPI content verification), build.yml (sign + publish), and release.yml, which runs only on a v* tag and publishes a changelog without building anything.

The toolchain each job runs in is its container.image, not its runs-on label. runs-on: python-ci only schedules the job onto a runner; every job then names the image it actually wants. ci-requirements.md is the current, authoritative list of images and per-job installs — read that rather than a copy here, so the two can't drift.

The repo expects one secret:

• RELEASE_TOKEN — a Forgejo PAT with:

  • write:package + read:package — for docker push to git.fabledsword.com
  • write:release — for the ext-<version> releases that cache the signed XPI
  • write:issue — for issue-management automation

  Generate at https://git.fabledsword.com/user/settings/applications. The injected GITHUB_TOKEN cannot be used because it lacks write:package.

AMO signing additionally needs MOZILLA_AMO_JWT_KEY / MOZILLA_AMO_JWT_SECRET. It runs on both channels and is cached per version: because the version is derived from commit time, dev and main derive the same number for the same source, so main finds dev's signature already cached and makes no second AMO call. That cache is why signing must be one-shot — AMO rejects a re-signed version.
