+# Amarillo
 
+**CRUD for carpool offers**
+
+An Amarillo is a [yellow-dressed person](https://www.dreamstime.com/sancti-spiritus-cuba-feb-road-spot-amarillos-yellow-ones-who-stop-cars-oblige-driver-to-give-lift-people-waiting-image130186034) helping others to find a car pool in Cuba. 
+
+## Setup
+
+- Python 3.9.2 with pip
+- python3-venv
+
+Create a virtual environment `python3 -m venv venv`. Activate the environment with `source venv/bin/activate` and install the dependencies `pip install -r requirements.txt`.
+
+Run `uvicorn amarillo.app.main:app`. 
+
+In development, you can use `--reload`. 
+
+## Environment Variables
+
+- `env`
+- `ADMIN_TOKEN`
+
+E.g. set the environment variable like this: `export ADMIN_TOKEN=YOUR_SECRET_TOKEN_HERE`.
+
+## Security
+
+All endpoints are protected by an API-Key in the HTTP header. 
+There is a special *admin* user. 
+For this user, the API-Key must be passed in as an environment variable when 
+Amarillo is started.
+
+The admin can create additional API-Keys in the `/agencyconf` endpoint. This 
+endpoint is always available but not always shown in `/docs`, especially not
+when running in production. 
+The Swagger docs for `/agencyconf` can be seen on the MFDZ demo server. 
+
+Permissions work this way
+- the admin is allowed to call all operations on all resources. Only the admin
+  can create new API-Keys by POSTing an `AgencyConf` JSON object to `/agencyconf`. 
+- API-Keys for agencies are allowed to POST/PUT/GET/DELETE their own 
+  resources and GET some public resources.
+
+## Development
+
+### GTFS-RT python bindings
+
+In case you modify or update the proto-files in app/proto, you'll need to regenerate the python bindings. First, create the python files:
+
+```sh
+$ cd app/proto
+$ protoc --version
+libprotoc 3.21.6
+$ protoc --proto_path=. --python_out=../services/gtfsrt gtfs-realtime.proto realtime_extension.proto
+$ sed 's/import gtfs_realtime_pb2/import app.services.gtfsrt.gtfs_realtime_pb2/g' ../services/gtfsrt/realtime_extension_pb2.py | sponge ../services/gtfsrt/realtime_extension_pb2.py
+```
+
+## Testing
+
+In the top directory, run `pytest app/tests`.
+
+## Docker
+
+Based on [tiangolo/uvicorn-gunicorn:python3.9-slim](https://github.com/tiangolo/uvicorn-gunicorn-docker)
+
+- build `docker build -t amarillo .`
+- run `docker run --rm --name amarillo -p 8000:80 -e MODULE_NAME=amarillo.app.main -e ADMIN_TOKEN=$ADMIN_TOKEN -e RIDE2GO_TOKEN=$RIDE2GO_TOKEN -e METRICS_USER=$METRICS_USER -e METRICS_PASSWORD=$METRICS_PASSWORD -e TZ=Europe/Berlin -v $(pwd)/data:/app/data amarillo`
