> A Virtualised Raspberry Pi inside a Docker image

Gives you access to a virtualised ARM based Raspberry Pi machine running the Raspian operating system.

This is not just a Raspian Docker image, it's a full ARM based Raspberry Pi virtual machine environment.

## Usage

```
docker run -it lukechilds/dockerpi
```

By default all filesystem changes will be lost on shutdown. You can persist filesystem changes between reboots by mounting the `/sdcard` volume on your host:

```
docker run -it -v $HOME/.dockerpi:/sdcard lukechilds/dockerpi
```

If you have a specific image you want to mount you can mount it at `/sdcard/filesystem.img`:

```
docker run -it -v /2019-09-26-raspbian-buster-lite.img:/sdcard/filesystem.img lukechilds/dockerpi
```

If you only want to mount your own image, you can download a much slimmer VM only Docker container that doesn't contain the Raspbian filesystem image:

[![Docker Image Size](https://badgen.net/docker/size/lukechilds/dockerpi/vm/amd64?icon=docker&label=lukechilds/dockerpi:vm)](https://hub.docker.com/r/lukechilds/dockerpi/tags?name=vm)

```
docker run -it -v /2019-09-26-raspbian-buster-lite.img:/sdcard/filesystem.img lukechilds/dockerpi:vm
```

## Which machines are supported?

By default a Raspberry Pi 1 is virtualised, however experimental support has been added for Pi 2 and Pi 3 machines.

You can specify a machine by passing the name as a CLI argument:

```
docker run -it lukechilds/dockerpi pi1
docker run -it lukechilds/dockerpi pi2
docker run -it lukechilds/dockerpi pi3
```

> **Note:** In the Pi 2 and Pi 3 machines, QEMU hangs once the machines are powered down requiring you to `docker kill` the container. See [#4](https://github.com/lukechilds/dockerpi/pull/4) for details.

## Wait, what?

A full ARM environment is created by using Docker to bootstrap a QEMU virtual machine. The Docker QEMU process virtualises a machine with a single core ARM11 CPU and 256MB RAM, just like the Raspberry Pi. The official Raspbian image is mounted and booted along with a modified QEMU compatible kernel.

You'll see the entire boot process logged to your TTY until you're prompted to log in with the username/password pi/raspberry.

## Build

Build this image yourself by checking out this repo, `cd` ing into it and running:

```
docker build -t lukechilds/dockerpi .
```

Build the VM only image with:

```
docker build -t lukechilds/dockerpi:vm --target dockerpi-vm .
```
