Dockerized environment to build Switchroot Android image

This repo provides 3 dockerfiles:

Dockerfile.env: Creates the basic environment + current source code, to start a full build. Used to create the switchroot:env docker image
Dockerfile.build: Triggers the actual Android build. Based on the switchroot:env image. Used to create the switchroot:build docker image
Dockerfile.build-latest: Updates the sources retreived when the switchroot:env docker image was created and triggers a build. Based on the switchroot:build docker image to - hopefully - save some rebuild time.

How to use

Install docker
Clone/Download this repo
Either prepend sudo to every command after this step, or allow the current user to run docker without sudo
Run ./docker-image-env.sh (Requires internet access. Should take less than an hour with a decent internet connection)
Run ./docker-image.build.sh (Doesn't require internet access. Should take between 3 to 8 hours, depending on your setup. Once finished building the last Android image, it may take a few more minutes to actually finish the docker command because of the large layer commit times)
Run ./extract-images.sh. It will copy the required images to ~/Downloads/images

After a successfull build, run ./docker-image.build-latest.sh (Requires internet access. Should take less time to finish than the first build)
Run ./extract-images.sh. It will copy the required images to ~/Downloads/images
