Uses wasp-payload-processor to build a payload parsing service for Thingy91 devices.
Examples of Thingy91 payloads received from Nordic Cloud supplied MQTT broker. See app/server.js for how this service processes payloads.
wasp-thingy91 can be run in a similar way to most nodejs applications. First install required dependencies using npm:
npm installFor integration testing, wasp-thingy91 depends on Kafka and Zookeeper. These can be brought locally up using docker:
docker-compose up -dYou can then run tests with:
npm testwasp-thingy91 is configured primarily using environment variables as follows:
| variable | required | default | description |
|---|---|---|---|
| WASP_SENSOR_TYPE | N | thingy91 |
Type of this sensor/thing for wasp-thing-service |
The following environment variables configure the use of wasp-payload-processor:
| variable | required | default | description |
|---|---|---|---|
| PORT | N | 3000 |
Port on which the service will listen |
| LOG_LEVEL | N | info |
Logging level. Valid values are [trace, debug, info, warn, error, fatal] |
| KAFKA_LOG_LEVEL | N | nothing |
Logging level for Kafka. Valid values are [debug, info, warn, error, nothing] |
| KAFKA_BROKERS | N | localhost:9092 |
List of addresses for the Kafka brokers |
| KAFKA_READINGS_TOPIC | N | readings |
Outgoing Kafka topic for readings |
| KAFKA_EVENTS_TOPIC | N | events |
Outgoing Kafka topic for events |
| KAFKA_PAYLOAD_ROUTING_PREFIX | N | payloads |
Prefix for incoming Kafka topics for payloads |
Install minikube and helm using Homebrew, then start minikube and update helm dependencies:
brew install minikube helm
minikube start
helm dependency update helm/wasp-thingy91
Eval is required to provide helm with visibility for your local docker image repository:
eval $(minikube docker-env)
Build the docker image (change src= to point to your local github token):
DOCKER_BUILDKIT=1 docker build -t wasp-thingy91:latest --secret id=github,src=<path/to/your/github_token> .
To run/deploy the application on kubernetes via helm charts use the following ct-values.yaml with the corresponding overrides:
helm install wasp-thingy91 helm/wasp-thingy91 -f helm/wasp-thingy91/ci/ct-values.yaml
Check the pods are running successfully using:
kubectl get pods -A
