This document discusses programming IoT devices with Docker. It begins with an overview of IoT and Docker, defining IoT as connecting devices over the internet and Docker as a platform for developing and running containerized applications. It then provides examples of programming IoT boards, sensors and gateways using Docker containers, including with Johnny-Five for Node.js, ESP32, Apache MyNewt, and building custom images. It emphasizes that Docker allows building once and running anywhere through isolated, portable containers.

 According to Gartner, the Internet of Things will balloon to
26 billion devices by 2020.
 There’s big money in these little devices: Gartner projects
IoT will result in $1.9 trillion in global economic “value-
add”—the combined benefits that businesses derive through
the sale and usage of IoT technology.

IoT Platform:
In simple words the purpose of any IoT device is to connect
with other IoT devices and applications (cloud-based mostly)
to relay information using internet transfer protocols.
The gap between the device sensors and data networks is
filled by an IoT Platform. Such a platform connects the data
network to the sensor arrangement and provides insights
using backend applications to make sense of plethora of data
generated by hundreds of sensors.
Example: Amazon Web Services (AWS) IoT, Microsoft Azure
IoT, Thinger.IO, ThingsBoard, Kaa IoT Platform, etc.

12. What is Docker?
12
 Docker is a platform for developing, shipping and running
applications using container virtualization technology.

13. What is Docker? (cont.)
13
 Using containers, everything required to make a piece of
software run is packaged into isolated containers.
 Unlike VMs, containers do not bundle a full operating
system - only libraries and settings required to make the
software work are needed.
 This makes for efficient, lightweight, self-contained
systems and guarantees that software will always run the
same, regardless of where it’s deployed.

15. What is Docker? (cont.)

 The Docker Platform consists of multiple products/tools:
 Docker Engine
 Docker Registry
 Docker Machine
 Docker Swarm
 Docker Compose
 Kitematic

16. What is Docker? (cont.)
16
docker info # Displays system wide information of Docker
docker build # Build an image from a Dockerfile
docker images # List all images on a Docker host
docker pull # Pull an image from a Registry
docker run # Run an image
docker ps # List all running and stopped instances
docker stop # Stop a running instances
docker rm # Remove an instance
docker rmi # Remove an image
docker stats # Show running containers‘ resource usage info
docker attach # Attach to a running container
docker logs # Fetch the logs of a container
docker inspect # Return low-level information on a container
docker history # Show the history of an image

 Linux Distribution: Ubuntu Desktop 17.04 (amd64)
 Docker Version: Docker 17.05-ce
https://www.docker.com/community-edition
https://store.docker.com/search?type=edition&offering=community
https://mobyproject.org/
https://github.com/moby/moby/releases

19. Docker Installation

 https://store.docker.com/search?offering=community&type=edi
tion
 sudo apt-get -y install apt-transport-https ca-certificates

 sudo apt-get -y install docker-ce
(OR)
 curl -fsSL https://get.docker.com/ | sh
 sudo usermod -aG docker $(whoami)
(for multi arch Docker)
 sudo apt install binfmt-support qemu-user-static

21. Docker Hub Registry

Boards USB Cable
Docker running
inside a computer

23. Enable USB Support for Docker

 Running docker cli with:
docker run …
--privileged
--device=/dev/ttyUSB0
-v /dev/bus/usb:/dev/bus/usb

sudo docker run -ti --privileged node /bin/bash
(in container)
npm install johnny-five
node helloworld.js
// file: helloworld.js

var board = new five.Board();
board.on("ready", function() {
// Create a standard `led` component instance
var led = new five.Led(13);
// "blink" the led in 1500ms
// on-off phase periods
led.blink(1500);
});

25. ESP32 …

bash file:
newt
 cd myproject
 ../newt version

27. Build your own recipe …
27
 Use Dockerfile and build your own new image
 Look into others Dockerfile from Docker Hub Registry, improved it
and start build your own images …
 mkdir myspecial1
 cd myimage
 nano Dockerfile
 docker build -t myspecial1 .
 docker run --privileged -v /dev/bus/usb:/dev/bus/usb
myspecial1 ...
