What is this all about?

This tutorial will turn your Raspberry PI into a simple Bluetooth audio receiver, which plays music through connected speakers. It's like a regular car audio system, but it can be used anywhere and it's a good value.

Commands for controlling the Raspberry Pi 2 LEDs.

See rpi-leds for a node module that does this.

Power (PWR) LED

OK (ACT) LED = led0
Power (PWR) LED = led1

Allow access

Would you love to get Docker up and running on you Raspberry Pi 2? Fortunately someone already did most of the leg work for you, as you will see from the article "Kick-Ass Raspberry Pi 2 having a forbidden love affair with Docker 1.4.1".

Check the official article "Installing Operating System Images" for more information on how to install this Debian Wheezy OS.

After you have downloaded and installed the image referenced in the article you're ready to do some adjustments to improve security.

Background

I assume you already have Docker up and running on your Raspberry Pi 2. If not, see this article.

The next natural step is to install Docker Compose (formerly Fig), but there's no ARM support out of the box. This recipe will help you install Docker Compose on your Raspberry Pi 2!

The following six steps will do the trick:

Get the docker-compose source code from git
