MQTT to HTTP Bridge

Requirements

• NodeJS v11+
• NPM

Install and Run

cp .env.sample .env

MQTT_USERNAME=CAYENNE_USER
MQTT_PASSWORD=CAYENNE_PASSWORD
PROXY_URL=https://requestvin.herokuapp.com/11w4pea1
TOPIC="/v1.6/devices/#"
TOPIC_REGEX="\/v1.6\/devices\/(.*)\/up\/(.*)"

Fill .env with appropriate values.

** Note: TOPIC_REGEX is a regex that will be used to extract the device id and channel from the MQTT topic. The first group is the device id and the second group is the value. **

npm install
node bridge.js

Run as a docker container

docker run -it -e MQTT_HOST=159.65.38.90 -e MQTT_USERNAME=globalsense -e MQTT_PASSWORD=Password1 -e PROXY_URL=https://lora-az-prod-eastus.mydevices.com/v1/networks/iotinabox/uplink mydevices/mqtt-bridge:latest

Deploy in Kubernetes

Copy deploy/configmap.example.yaml to deploy/configmap.yaml and fill in the values.

kubectl -n integrations apply -f deploy/configmap.yaml

kubectl -n integrations apply -f deploy/deployment.yaml

This will create a deployment with one replica. You can scale it up to more replicas if you want to run more instances of the bridge.

kubectl -n integrations scale deployment NAME_OF_DEPLOYMENT --replicas=3

Re-install deployment

kubectl -n integrations delete deployment NAME_OF_DEPLOYMENT
