The most important upgrade of our second image is the support for Docker 1.5.0 which has been released just recently. Most noteworthy about Docker 1.5.0 is the new support for IPv6, read-only containers and advanced statistics for image resource consumption. We find the last one especially interesting for people like us who are running Docker on small devices. One thing we already had in the last incarnation of our image is the support of OverlayFS. OverlayFS is one of several storage drivers for Docker. The biggest distinction to other storage options, like lvm or btrfs, is the performance it offers. Summary of changesHere is a list of the most important changes to the SD card image. We … - upgraded the linux kernel from 3.18.6 to 3.18.8
- added kernel headers to support compilation of custom modules
- upgraded from Docker 1.4.1 to 1.5.0
- added support for using a USB to TTL serial console cable
- added bash completion for Docker commands
- lots of smaller fixes and improvements
Besides that we kept some features which were already awesome - the image is based on Raspbian Wheezy
- support for OverlayFS by default
- support for Raspberry Pi 1 & 2 with the same SD card image (dual kernel)
- How to get started
Download our SD card image and flash it on your own SD card. Here is a short guide on how to do this for Mac, Windows and Linux users. Afterwards insert the SD card in your Raspberry Pi and wait while it boots. The first time will take a little longer as it resizes the file system to its maximum and reboots again. At the boot prompt log in with user “pi” and password “raspberry” (or with a privileged user “root” and password “hypriot”). One thing that is still worth mentioning is that you need special ARM-compatible Docker Images. Standard x86-64 Docker Images from the Docker Hub won’t work. That’s the reason why we’ve created a number of ARM compatible Docker Images to get you started. Whether you prefer Java, Python, Node.js or io.js - we have you covered! You will find these images and more at our place on the Docker Hub. After booting our image on your Pi these base images are just a “docker pull” away. For example “docker pull hypriot/rpi-node”. As you can see - getting started with Docker on your Raspberry Pi just got so much easier! 方便坛友下载，已把镜像上传到百度盘
