+Set `APIDOC_URL` to the public base URL for your deployment (for example `https://api.example.com` or your subdomain). The container entrypoint applies this value to `apidoc.json` and the `apidoc` section of `package.json`, then runs `npm run docs` before starting the server so generated HTML matches each instance. The compose file mounts `./.env` to `/home/safeuser/psf-bch-api/.env` so it matches `dotenv.config()` in the app.

+# 2026-04-02 Update Log
+
+## Summary
+
+Docker deployments now run `npm run docs` at container start via an entrypoint script, and optionally apply `APIDOC_URL` from the environment so apiDoc HTML matches each deployment subdomain or public URL.
+
+## Changes Made
+
+- Added `scripts/patch-apidoc-from-env.js` to set `apidoc.json` and `package.json` `apidoc.url` from `APIDOC_URL` (dotenv loads the project `.env`, same path as `bin/server.js`).
+- Added `production/docker/entrypoint.sh` to run the patch script, `npm run docs`, then `exec npm start`.
+- Updated `production/docker/Dockerfile` to remove build-time `npm run docs`, copy the entrypoint and patch script from the build context, and use `ENTRYPOINT` for the shell script.
+- Updated `production/docker/docker-compose.yml` to use build `context: ../..` and `dockerfile: production/docker/Dockerfile` so COPY paths resolve from the repository root.
+- Compose mounts `./.env` at `/home/safeuser/psf-bch-api/.env` so the app and entrypoint share one file (not `/home/safeuser/.env`).
+- Documented `APIDOC_URL` in `.env-example`, `production/docker/.env-example`, and `README.md` (Production Docker section).
+
+## Outcome
+
+- Operators can set `APIDOC_URL` in the mounted `.env` (for example `https://api.example.com`) per instance without rebuilding the image for each subdomain.
+- The HTML apiDoc bundle is regenerated on every container start so it stays aligned with the configured URL.
