Goals
Containers and the Internet of Things
evangelizing to use Docker container on ARM boards
convincing Docker containers for IoT applications
enabling the Docker ecosystem on low-powered devices
Gartner says 6.4 billion connected "Things" will be in use in 2016, up 30 percent
from 2015
In turn, that number is expected to further explode by 2020, where the IoT
market will include 20.8 billion things
--> pushing the Docker technology into the IoT world

Ways - 1. Iteration
run a proof-of-concept
select the Raspberry Pi as a popular device
tried to run Docker on a RPi model B
found only outdated tutorials
using ArchLinux was "special"
upgrading Raspbian takes 5 to 6 hours
let's improve this situation!
need to compile Docker on ARMv6
need to create a special Linux kernel
need to package all into a new SD card image
5 / 20

26/02/16 4:33 PMTitle
--> in the end, we built HypriotOS (based on Raspbian/Debian)
6 / 20

26/02/16 4:33 PMTitle
Ways - 2. Iteration - Updates
porting the complete Docker ecosystem to ARM
Docker Compose
Docker Swarm
Docker Machine
created all Docker releases for ARM just-in-time
from Docker 1.4 until 1.10 (sometimes minutes after release!)
shipping every new Linux kernel version
from 3.18 until 4.1.12
switching to Raspbian Jessie
included support for the Raspberry 7" Touch Display
7 / 20

26/02/16 4:33 PMTitle
--> complete Docker toolset on ARM
8 / 20

26/02/16 4:33 PMTitle
Ways - 3. Iteration - Cluster Lab
create a learning platform for clusters
cheap, using 3 to 5 Raspberry Pi's and a network switch
easy to setup a cluster with HypriotOS and Docker
Google's Kubernetes team members did it!
ready for classes in univercity
ready for talks and live demos
ready for professional trainings too

26/02/16 4:33 PMTitle
--> Hypriot Cluster Lab is just flash and boot.
10 / 20

26/02/16 4:33 PMTitle
Ways - 4. Iteration (under construction!)
create a container OS for ARM devices
using a mainline Linux distro (Debian Jessie)
building blocks for ready-to-use SD images
support all important ARM devices
Raspberry Pi
ODROID C1+, XU4
Banana Pi
BeagleBoneBlack
Pine A64+
ODROID C2

26/02/16 4:33 PMTitle
--> device list will be continued...
12 / 20

26/02/16 4:33 PMTitle
Concepts - Easy Building Blocks
small and simple pieces
easy to understand
easy to develop
easy to maintain
--> combine it like LEGO bricks
13 / 20

26/02/16 4:33 PMTitle
Concepts - Full Transparency
develop locally (Vagrant + Docker)
automated build server (Travis + Docker)
automated testing (ServerSpec)
automated releasing (GitHub releases)
--> every single detail is visible
14 / 20

26/02/16 4:33 PMTitle
Concepts - Parts and Ideas
the new HypriotOS
a Debian-based root filesystem (32 and 64-bit)
a board specific layer
Linux kernel
firmware
bootloader
a common layer
Hypriot specific settings and tools
Docker Engine
Compose, Swarm, Machine
an optional application layer
Hypriot Cluster Lab
--> creating ready-to-run SD card images
15 / 20

26/02/16 4:33 PMTitle
Concepts - Open Source Everything
All these parts are already open sourced at GitHub https://github.com/hypriot
root filesystem: https://github.com/hypriot/os-rootfs
raw image: https://github.com/hypriot/image-builder-raw
Raspberry Pi: https://github.com/hypriot/image-builder-rpi
ODROID C1/C1+: https://github.com/hypriot/image-builder-odroid-c1
Banana Pi: https://github.com/hypriot/image-builder-bananapi
Come and try it out
hack on it
improve it
add new boards and features
--> we need your help !

26/02/16 4:33 PMTitle
Current Status of HypriotOS
active Docker ARM community
Gitter channel (> 280 users)
Twitter is growing fast (> 750 followers)
increasing download numbers (Cloudflare helps)
everybody is using Docker on ARM right now
HypriotOS is the easiest way around
download and boot takes just 5 minutes
--> break all limits with the new HypriotOS !
