IBM Watson IoT

In this tutorial you will be guided through the process of setting up your device. In this case a Raspberry Pi 3 - to IBM Watson IoT. By using the IBM IoT container available on the extra-containers repo, together with your FoundriesFactory, you will learn how to connect your device to the cloud with just a few simple commands. Before you know it, data - like CPU and RAM usage - will be flowing through the IBM Watson IoT, allowing you to easily integrate your device data with any IBM Service.

Once you install your app, you just need to load one config file over fioctl and the device will start to send important system information to IBM Watson IoT. In this tutorial we’re assuming that you already have an IBM Watson IoT Account and your Raspberry Pi 3 is already connected to your FoundriesFactory.

IBM Configuration

For the purposes of this tutorial we will begin by completing the necessary steps to configure IBM IoT and next we will configure and enable the IBM IoT container using FoundriesFactory.

Create your Resource

First, we need to create resource.

Go to: “IBM Dashboard” page.

At the top right of the window, click on “Create resource”.

Create resource

Search for “internet of things” and select the “Internet of Things Platform” box.

You should now see the “Internet of Things Platform-te” page.

Click on “Launch”

Create Device

Now we are ready to create our first device. We are using the Raspberry Pi 3B for our demonstration but you may use any LmP device for the rest of this tutorial.

On the Browse Devices window click on the “Create a device” button.

Create a device

Create a device

In the “Add Device” dialog, enter your “Device Type”. In my case, I will use: RPi3B

Enter your “Device ID”. In my case, I will use: 0001

Click on “Next”.

Add Device

Add Device

In the “Device Information”, all fields are optional. In my case, I will complete at least model and location:

In the “Security”, we will use “Auto-Generated authentication token”.

Click on “Next”

Finally in the “Summary”, click on “Finish”

Add device summary

After finishing the device creation, you will see important information.

Save the “Organization ID”, “Device Type”, “Device ID” and the “Authentication Token”

FoundriesFactory

Cloning your repository

To interact with your FoundriesFactory you’ll first need to download the necessary repositories, change the code and send it back to the server.

First, navigate to Foundries App, find your Factory and the source code.

Device activation page

Device activation page

Open the container repository and clone it on your host machine:

# Ubuntu Host Machine
$ mkdir getstartedvideo
$ cd getstartevideo
$ git clone https://source.foundries.io/factories/getstartedvideo/containers.git/
$ cd containers

In order to enable IBM IoT app we will need to clone some files from our reference repository:

# Ubuntu Host Machine
$ git remote add fio https://github.com/foundriesio/extra-containers.git
$ git remote update
$ git checkout remotes/fio/master -- ibm-iotsdk

Edit the docker compose app file and update the Factory name:

# Ubuntu Host Machine
$ vim ibm-iotsdk/docker-compose.yml

ibm-iotsdk/docker-compose.yml:

# ibm-iotsdk/docker-compose.yml
version: "3"
services:
  ibm-iotsdk:
    image: hub.foundries.io/<YOUR_FACTORY_NAME>/ibm-iotsdk:latest
    tmpfs:
        - /run
        - /var/lock
        - /var/log
    volumes:
        - /var/run/secrets:/config
    tty: true
    network_mode: "host"
    privileged: true
    restart: always

Add the changes to your Factory and wait for it to finish compiling your app:

# Ubuntu Host Machine
$ git add ibm-iotsdk/
$ git commit "Adding new ibm-iotsdk app"
$ git push
Building App

Building App

Enabling the App on your Device

In the following steps we assume you have your Raspberry Pi 3 with Foundries.io’s LmP running and correctly registered to your Factory.

With fioctl, we will enable the application “ibm-iotsdk” on your device registered with the name raspberrypi3. For more information about how to register and enable application, check the page Configuring Devices:

# Ubuntu Host Machine
# Configure the device to run the "ibm-iotsdk" app
$ fioctl devices config updates raspberrypi3 --apps ibm-iotsdk --tags master

On your Raspberry Pi, you should receive the update soon. You can watch the logs by running the following commands:

# Ubuntu Host Machine
$ ssh fio@raspberrypi3-64.local
# Raspberry Pi 3 Target Machine
$ sudo journalctl -f -u aktualizr-lite

Debugging the IBM IoT Container APP

In your Raspberry Pi 3 you can check the running container and copy the container ID:

# Raspberry Pi 3 Target Machine
$ docker ps
docker ps

docker ps

With the container ID check the container logs:

# Raspberry Pi 3 Target Machine
$ docker logs -f 20a1ede9c146
docker log

docker log

As you can see, IBM IoT app is waiting for config files to connect and start sending data to the cloud.

Config files

We need to send a file configuration to the device. Create a file with some variables needed on the application.

Create a file “ibm.config” and copy the “Organization ID”, “Device Type”, “Device ID” and the “Authentication Token” to the variables:

# Ubuntu Host Machine
$ mkdir config
$ cd config
$ vim ibm.config

ibm.config:

WIOTP_IDENTITY_ORGID='rmboq4'
WIOTP_IDENTITY_TYPEID='RPi3B'
WIOTP_IDENTITY_DEVICEID='0001'
WIOTP_AUTH_TOKEN=XXXXXXXXXX

Use fioctl to send the files to the device safely:

# Ubuntu Host Machine
$ fioctl devices config set homeassistant32 ibm.config="$(cat ibm.config)""

After some time, the files will be copied to the folder “/var/run/secrets” on your device:

# Raspberry Pi 3 Target Machine
$ root@raspberrypi3:/home/prjs/ibm/config# ls /var/run/secrets/
ibm.config

Connect and send data to IBM IoT

As soon as the container finds the “ibm.config” file, it will automatically start sending data to the IBM Watson IoT Cloud.
