README.md

Using space-shuttle-demo with MQTT based ingestion

If you want to use MQTT based ingestion follow that README instruction with the following changes:

• you should create Mosquitto service instance (recommended name: space-shuttle-mqtt) instead of gateway and zookeeper instances
• while pushing an app to cloud foundry you should use manifest-mqtt.yml file by calling cf push -f manifest-mqtt.yml
• you should use ingest_mqtt.sh script located in mqtt directory to send data to mqtt. More information below

Get mosquitto credentials

After your application is pushed, you can type cf env space-shuttle in your terminal. You should see JSON object. The most interesting part is mosquitto credentials:

"mosquitto": [
  {
    "credentials": {
      "port": "32826",
      "ports": {
        "1883/tcp": "32826"
      },
      "username": "sample_user",
      "password": "sample_pass"
    },
    "name": "space-shuttle-mqtt",
     ..........
  }
]

You will need port, username and password to connect to mosquitto instance and ingest data to your application.

Install mosquitto clients on your local machine

To install Mosquitto on you local machine, follow the instructions here: http://www.eclipse.org/mosquitto/download/

Run ingestion script

In a terminal:

cd mqtt
vim ingest_mqtt.sh
  {edit first two lines of this file}
    {change HOST from 'localhost' to 'mqtt.<platform-domain>'}
    {change PORT from '1883' to 'port' acquired in "Get mosquitto credentials" section}
./ingest_mqtt.sh
{enter username - the same that you get in ""Get mosquitto credentials" section}
{enter password - the same that you get in "Get mosquitto credentials" section}
