Introductionit's all about team work

Me, Dieter Reuter

Consultant at daytimeHacker & Pirate by night

Hypriot Team

five individuals: Andreas, Dieter, Govinda, Mathias, Stefan[x] devs[x] devops[x] architects[x] consultants

--> We're scaling Docker containers - in a different way!

GoalsContainers 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 percentfrom 2015

In turn, that number is expected to further explode by 2020, where the IoTmarket will include 20.8 billion things

--> pushing the Docker technology into the IoT world

Ways - 1. Iterationrun a proof-of-concept

select the Raspberry Pi as a popular device

tried to run Docker on a RPi model B

found only outdated tutorialsusing ArchLinux was "special"upgrading Raspbian takes 5 to 6 hours

let's improve this situation!

need to compile Docker on ARMv6need to create a special Linux kernelneed to package all into a new SD card image

26/02/16 4:33 PMTitle


--> in the end, we built HypriotOS (based on Raspbian/Debian)

26/02/16 4:33 PMTitle


Ways - 2. Iteration - Updatesporting 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

26/02/16 4:33 PMTitle


--> complete Docker toolset on ARM

8 / 20

26/02/16 4:33 PMTitle


Ways - 3. Iteration - Cluster Labcreate 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

--> 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

Concepts - Easy Building Blockssmall 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 Transparencydevelop locally (Vagrant + Docker)

automated build server (Travis + Docker)

automated testing (ServerSpec)

automated releasing (GitHub releases)

--> every single detail is visible

26/02/16 4:33 PMTitle


Concepts - Parts and Ideasthe new HypriotOS

a Debian-based root filesystem (32 and 64-bit)

a board specific layer

Linux kernelfirmwarebootloader

a common layer

Hypriot specific settings and toolsDocker EngineCompose, Swarm, Machine

an optional application layer

Hypriot Cluster Lab

--> creating ready-to-run SD card images

Concepts - Open Source EverythingAll 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 !

Current Status of HypriotOSactive 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 !
