+# Running dynamicweb with Docker Compose
+
+A self-contained test/dev stack: Postgres, Redis, the web app and a Celery worker.
+Nothing else needs to be installed on the server.
+
+## Start
+
+```sh
+git clone <this repo> && cd dynamicweb
+docker compose up -d --build
+docker compose logs -f web      # wait for "Starting development server"
+```
+
+The first start takes a few minutes: it builds the image, creates the database,
+runs all migrations and generates a Django secret key (kept in the `appdata` volume).
+
+The app listens on port **8000**. Open it at `http://<server-ip>:8000/`
+(open the port in the server firewall if needed).
+
+## Configuration
+
+- Defaults for everything are in `.env.docker` (committed, dev values only).
+- To override a value, create a `.env` file next to `docker-compose.yml`
+  (optional, git-ignored). Values there win over `.env.docker`.
+
+### Using your own Postgres instead of the bundled one
+
+Set the connection in `.env`:
+
+```
+POSTGRES_HOST=<host>
+POSTGRES_PORT=5432
+POSTGRES_DB=<db>
+POSTGRES_USER=<user>
+POSTGRES_PASSWORD=<password>
+```
+
+then start everything except the bundled database:
+
+```sh
+docker compose up -d --build --no-deps web celery redis
+```
+
+## Testing all the sites
+
+The project serves many websites from one app and chooses the site from the
+hostname. In this test setup you don't need DNS or `/etc/hosts`: a dev-only
+switcher picks the site from `?site=<domain>` and remembers it in a cookie.
+
+Open **`/dev-sites/`** on any host for a page of clickable links
+(`http://<server-ip>:8000/dev-sites/`). On a machine running the stack locally:
+
+| Site | Link |
+|---|---|
+| ungleich.ch | http://localhost:8000/?site=ungleich.ch |
+| blog.ungleich.ch | http://localhost:8000/?site=blog.ungleich.ch |
+| comic.ungleich.ch | http://localhost:8000/?site=comic.ungleich.ch |
+| digitalglarus.ch | http://localhost:8000/?site=digitalglarus.ch |
+| datacenterlight.ch | http://localhost:8000/?site=datacenterlight.ch |
+| rails-hosting.ch | http://localhost:8000/?site=rails-hosting.ch |
+| django-hosting.ch | http://localhost:8000/?site=django-hosting.ch |
+| node-hosting.ch | http://localhost:8000/?site=node-hosting.ch |
+| devuanhosting.ch | http://localhost:8000/?site=devuanhosting.ch |
+| devuanhosting.com | http://localhost:8000/?site=devuanhosting.com |
+| ipv6onlyhosting.com | http://localhost:8000/?site=ipv6onlyhosting.com |
+| digitalezukunft.ch | http://localhost:8000/?site=digitalezukunft.ch |
+| hack4glarus.ch | http://localhost:8000/?site=hack4glarus.ch |
+| xn--nglarus-n2a.ch | http://localhost:8000/?site=xn--nglarus-n2a.ch |
+
+Use `?site=` (empty) to clear the choice. To add a site, add it to
+`UNGLEICH_SITE_CONFIGS` in `.env.docker` (a `Site` row is created on start).
+
+## Loading data (optional)
+
+The database starts empty, so the sites are mostly blank. To load a dump, put a
+plain-SQL `*.sql` or `*.sql.gz` file in `db-init/` **before the first start**; Postgres
+restores it automatically. To reload: `docker compose down -v` (this deletes the
+volumes) and start again. Dumps are git-ignored because they contain personal data.
+
+## Useful commands
+
+```sh
+docker compose ps                         # what is running
+docker compose logs -f web celery         # logs
+docker compose up -d --build              # rebuild after code changes (code is baked into the image)
+docker compose exec web python manage.py createsuperuser
+docker compose down                       # stop (keeps data); add -v to wipe it
+```
+
+## Limitations of the test setup
+
+OpenNebula (VM creation), LDAP login and Stripe payments use placeholders and
+will not work. Email is printed to the web container log. `DEBUG=True` is on.
