Seat-adjuster example

⚠️ This example is currently not executable from within the vehicle-app-pytthon-sdk's devContainer. Please use the "import example" feature of the related vehicle-app-python-template repository. Also, building the docker container for this example needs to be done after the import within the Python template's devContainer.

Run this example from your Python app development repo

It is possible to import and run this example from your app development repository, which you already have created or could create from our vehicle-app-python-template repository.

1. Importing the example

   Use the VS Code task Import example app from SDK (to get there press Ctrl+Shift+P and select Tasks: Run Task) and choose seat-adjuster from the list.

   ⚠️ Make sure you have commited or stash all your possible changes within the app folder, because the files of that folder will be overwritten by the files of this example.

2. Running this example with Dapr middleware

   Use the VS Code tasks Local Runtime - Up and Local Runtime - Run VehicleApp to start the necessary runtime components and this app itself.

   Alternatively, the app can also be deployed in a k3d runtime - use task K3D Runtime - Deploy VehicleApp.

Executing with "native" middleware (without Dapr runtime)

If you like to run this example without using Dapr as middleware, you may need to provide some environment variables to the seat-adjuster process, which define the middleware type being native and where to find the required runtime components:

Variable name	Default value	Description
SDV_MIDDLEWARE_TYPE	"dapr"	Defines the middleware type -> set to "native"
SDV_MQTT_ADDRESS	"mqtt://localhost:1883"	Address (and port) of the MQTT broker
SDV_VEHICLEDATABROKER_ADDRESS	"grpc://localhost:55555"	Address (and port) of the KUKSA Data Broker

Building a Docker image

This example app provides a Dockerfile to enable creating a Docker container image to run it. The image must be build passing the repositories root folder as build context, e.g.:

docker build -f app/Dockerfile .

⚠️ If your build environment works behind (corporate) proxy, please remember telling docker your proxy configuration. If you've set the respective environment variables, this might work:

docker build -f app/Dockerfile . --build-arg http_proxy --build-arg HTTP_PROXY --build-arg https_proxy --build-arg HTTPS_PROXY --build-arg no_proxy --build-arg NO_PROXY
