Prepare release notes for next HypriotOS v1.1.0 release

[DieterReuter]

HypriotOS 1.1.0

HypriotOS for the Raspberry Pi is a Debian-based Container OS focused on security and minimal size with all the necessary Docker tools already pre-installed. It is heavily inspired by Raspbian and supports absolutely all Raspberry Pi models (1, 2, 3, Zero & Compute Module) out-of-the-box. The Linux kernel is optimized for use of Docker containers and runs on both ARMv6 and ARMv7 CPU's.

From Zero to Docker in five minutes only: Downloading the SD card image, flashing it to a SD card and booting up the Raspberry Pi takes less than five minutes - and the latest Docker Engine is already up and running.

Contents

• Linux Kernel 4.4.24 (optimized for Docker)
  • dual-arch kernel for ARMv6 and ARMv7 (supports all Raspberry Pi models)
• Docker Engine 1.12.2 (officially build by Docker)
• Docker Machine 0.8.2
• Docker Compose 1.8.1
• Hypriot Device-Init 0.1.8
• HypriotOS-RootFS 1.0.0 - Raspbian/Jessie "Raspbian GNU/Linux 8 (jessie)"

  Features

• The root file system of the SD card will be automatically resized on first boot
• No built-in "root" user for increased security
• Only a single standard user with sudo rights (username "pirate", password "hypriot")
  • User "pirate" is member of group "docker", can start docker commands directly
  • User "pirate" is member of group "video", can access the Raspberry Pi camera module
• device-init allows image customization before first boot
  • Standard hostname "black-pearl", can be configured in /boot/device-init.yaml
  • WiFi can be configured via device-init in /boot/device-init.yaml
  • Hypriot Flash tool directly supports device-init configuration
• Avahi service discovery built-in
  • find your Pi with a simple ping black-pearl.local or ping black-pearl on the network
• Console login via UART pins is enabled by default (for all Raspberry Pi models including Pi 3)
• Almost all WiFi firmware included for maximum compatibility (atheros, brcm80211, libertas, ralink, realtek)
• Using Overlay filesystem for Docker storage-driver is activated by default

  Improvements

• Reduced Image size for quicker SD card flashing (1000 MB/1.1.0 vs. 1300 MB/v0.8.4)
  • flashing to a SanDisk Ultra 16GB microSD card takes 01:56min only (2014 MBP, OS X 10.11)
• Reduced .img.zip size for smaller and faster downloads (240 MB/v1.1.0 vs. 504 MB/v0.8.4)
• Optimized file system to support more Inodes (1x Inode per 4 KB block)
• Faster boot times (measured with a freshly flashed SD card, no containers, no additional apps)
  • first boot: 19 sec. from power-on to login prompt on UART console
  • normal boot: 15-17 sec. from power-on to login prompt on UART console
  • reboot: 22 sec. to login prompt on UART console
• Minimized memory usage, 41 MB only (new install, right after boot, w/ SSH session)
• Minimized disk usage, 626 MB only (new install)

Removed Features

• Hypriot Cluster Lab (already available as separate .deb package)

  Fixed Issues

• this release works on all Raspberry Pi models (1, 2, 3, Zero & Compute Module) as the Docker Engine 1.12.2 is built for ARMv6

  Quick Installation

$ flash https://github.com/hypriot/image-builder-rpi/releases/download/v1.1.0/hypriotos-rpi-v1.1.0.img.zip
$ ssh pirate@black-pearl.local

• login with username "pirate", password "hypriot"

  Easy upgrade from HypriotOS 1.0.0 and 1.0.1

$ sudo apt-get update
$ sudo apt-get upgrade -y
$ sudo reboot
