icwe-demo

WasmIoT demonstration for ICWE 2024 conference

Running the test setup in docker

For convenience there is a test_system/docker-compose.yml and test_system/start.sh scripts. The start.sh script will start the WasmIoT orchestrator (orchestrator), the ICWE2024 demo (icwe-demo) and two wasmiot supervisors (raspi1) and raspi2).

To start all or any service, run the following command:

./test_system/start.sh [service]

When starting from devcontainer, the default app is icwe-demo. To start the necessary services, run the following command:

./test_system/start.sh orchestrator raspi1 raspi2

Running UI locally

Create a python virtual environment and install the requirements:

python3 -m venv .venv
source .venv/bin/activate
pip install -e .[dev]

Run the UI:

# Optional: set the environment variable to the URL of the WasmIoT server
export WASMIOT_ORCHESTRATOR_URL=http://orchestrator.local:5000
python -m icwe-demo

    abstract="In this paper we introduce a demonstration of our prototype orchestration system utilising WebAssembly to achieve isomorphism for a liquid software IoT system. The demonstration hardware consists of two Raspberry Pi IoT devices and a computer acting as the orchestrator. The audience can interact with the orchestrator through a web interface to deploy different software configurations to the devices, and observe the deployment process as well as the deployed application in action.",
