rpi-docker-development

Lets make raspberry development easy by using docker:

1. Emulate an raspberry device on your development machine.

2. Develop your raspberry app by using docker container with full access to the hardware.

3. Build your raspberry os image and deploy to sd card or simply pull the docker container on raspberry.

Prepare your host

Install:

• docker
• docker-compose

Prepare emulator

Run:

• docker-compose build to build your emulator container
• docker-compose run emulator /emulator-prepare to prepare raspberry emulation

Run raspberry

Run docker-compose run emulator emulator-run and you will have a working raspberry shell.

Setup docker and docker-compose on emulated raspberry

Run on raspberry emulation shell /host/rpi/setup-docker.

Or run on your development host docker-compose run emulator /host/rpi/setup-docker.

Develop your raspberry docker app

You have to make sure to use a cross-buildable container base image or simply use the provided base image in docker/rpi/base/Dockerfile (look at docker/rpi/docker-compose.yml and docker/rpi/wiringpi/Dockerfile).

Limitations

Sound

Sound is not supported as you have to pass your drive to the emulator instance. If you want to do so, uncomment the line export QEMU_AUDIO_DRV=none in file docker/emulator/emulator-run and rebuild the image ('docker-compose rebuild').

GUI

At the moment there is no graphical user interface support. If you need one, a good point to start is to remove the -nographic parameter in docker/emulator/emulator-run and pass a device in docker-compose.yml.
