This creates `XPI/unsigned/LinkLog-0.1.0.xpi` from the `webextension/` package and excludes macOS metadata and minified artifacts. The version is read from `webextension/manifest.json`. The `XPI/signed/` directory is reserved for signed release bundles.
|

|
||||
## Docker Deployment
|
||||
|
||||
The main `docker-compose.yml` is the production deployment. It does not publish port 8000 on the host; the application is reachable through Traefik on the external `linklog_traefik` network. Set `LINKLOG_PUBLIC_URL` to the DNS hostname served by Traefik. The default is the documentation hostname `linklog.example.com`, which must be replaced for a real deployment.
|
||||
|
||||
For local development with direct access, use the separate file:
|
||||
|
||||
```sh
|
||||
docker compose -f docker-compose.local.yml up --build
|
||||
```
|
||||
|
||||
This publishes `${APP_PORT:-8000}` and defaults the application URL to `http://localhost:8000`. Do not use the local file for an Internet-facing deployment.
|
||||
|
||||
## Releases
|
||||
|
||||
Releases run in Gitea Actions when a `v*` tag is pushed. The Docker release version comes from `frontend/version.json`; the Firefox plugin version comes from `webextension/manifest.json`. CI also requires both to match `LINKLOG_VERSION`'s default in `backend/app/core/config.py`.

### SA-007: Production Compose configuration exposes the application directly
|
||||
|
||||
**Severity:** Medium/High
|
||||
**Evidence:** `docker-compose.yml` publishes `${APP_PORT:-8000}:8000` while also configuring Traefik labels. The file uses an external `linklog_traefik` network and deployment-specific labels.
|
||||
**Severity:** Medium/High, remediated in current worktree
|
||||
**Evidence before remediation:** `docker-compose.yml` published `${APP_PORT:-8000}:8000` while also configuring Traefik labels. The file uses an external `linklog_traefik` network and deployment-specific labels.
|
||||
**Impact:** The application can bypass the reverse proxy and any TLS, authentication middleware, rate limiting, or security headers configured there. The default `LINKLOG_PUBLIC_URL=localhost` is also unsuitable for a public deployment. A network or label mismatch can silently expose an unprotected direct endpoint or make operators disable controls to restore access.
|
||||
|
||||
**Recommendation:** Split local development and production Compose files. In production, do not publish the application port to the host; attach it only to the reverse-proxy network. Ensure the app and Traefik share the same explicitly named network and validate the effective rendered configuration in CI. Require a non-local public hostname, TLS, security headers, request-size limits, and proxy-level rate limiting. Keep the direct port only in a documented local profile.
|
||||
**Current state:** The production `docker-compose.yml` no longer publishes port 8000 and attaches the app only to the external `linklog_traefik` network. Its public hostname fallback is `linklog.example.com`, and both Traefik routers use the same `LINKLOG_PUBLIC_URL`. Direct host access is available only through the explicitly named `docker-compose.local.yml` development file. `.env.example` and application settings use `linklog.example.com` as the documented default.
|
||||
|
||||
**Priority:** High for Internet-facing deployments.
|
||||
**Residual impact:** Operators must replace the documentation hostname, ensure the external network is the one used by Traefik, and validate the rendered Compose configuration and proxy middleware in their deployment. The local Compose file must not be exposed to the Internet.
|
||||
|
||||
**Recommendation:** Keep production and local Compose invocations separate, require a real DNS hostname and TLS in deployment checks, and add CI validation for the rendered production configuration and network labels.
|
||||
|
||||
**Priority:** Completed in code; deployment validation remains.

### Assistant outcome
|

Hardened the production Compose deployment by removing direct host port publication, keeping the app on the external Traefik network, and using `linklog.example.com` as the default public hostname. Added `docker-compose.local.yml` for explicit local direct-port development, updated `.env.example`, backend defaults, README deployment instructions, and SA-007 status.
