Dialogflow Adafruit Forwarder

Application which forwards messages from Dialogflow to Adafruit, so you do not have to use Google Cloud Functions

Purpose

dialogflow-adafruit-forwarder lets you control your Openstack setup with your Google Home. This application is split into multiple parts; internet-part (this appliaction) and intranet-part.

Thanks to this architecture it is possible to control your Openstack setup, without connecting it to the internet.

The main purpose of this project is to forward the incoming webhook POST-bodies from Dialogflow to Adafruit, listen until an answer gets published by google-home-openstack and then send a HTTP response back to Dialogflow.

Getting Started

From Source

To build it from source, make sure you have NodeJS 9.x.x and Git installed.

# Clone the repository
git clone https://github.com/brunnel6/dialogflow-adafruit-forwarder.git

# Install the dependencies
npm install
# Build the application
npm run build

# Run the application with your settings
ADAFRUIT_KEY=<KEY> ADAFRUIT_USERNAME=<USERNAME> ADAFRUIT_FEED_ID_IN=<ID> ADAFRUIT_FEED_ID_OUT=<ID> npm start
# curl -X POST http://localhost:3000/ -H 'content-type: application/json' -d '{"query": "123123"}'

Docker

You can use Docker 18.x.x-ce to run the application, without installing NodeJS on your machine.

wget https://raw.githubusercontent.com/BRUNNEL6/dialogflow-adafruit-forwarder/master/default.env

# Edit configuration file
vi default.env

docker run \
  --env-file ./default.env \
  -p 3000:3000 \
  -ti brunnel6/dialogflow-adafruit-forwarder:latest

docker-compose (Automatic container updates / SSL)

This docker-compose configuration starts v2tec/watchtower in addition to dialogflow-adafruit-forwarder. Watchtower watches over the docker image and updates it, if a new docker image version is public.

wget https://raw.githubusercontent.com/BRUNNEL6/dialogflow-adafruit-forwarder/master/default.env
wget https://raw.githubusercontent.com/BRUNNEL6/dialogflow-adafruit-forwarder/master/docker-compose.yml
# Edit configuration file
vi default.env
mv default.env cred.env

# Start applications
docker-compose up

Move your SSL certifiaces into the certs folder of this repository. The cert / key must have the same name as the defined VIRTUAL_HOST environment variable (in the cred.env file)

mkdir certs

mv /path/to/mydomain.com.key certs/
