Android Open Source Project Docker Build Environment

The goal of this Docker image is to maintain a minimal build environment for AOSP.

Developers can use the Docker image to build directly while running the distribution of choice, without having to worry about breaking the AOSP build due to package updates as is sometimes common on rolling distributions like Arch Linux.

Production build servers and integration test servers should also use the same Docker image and environment. This eliminate most surprises in breakages by by empowering developers and production builds to use the exact same environment. The hope is that breakages will be caught earlier by the devs.

How it Works

The Dockerfile contains the minimal packages necessary to build Android based on the main Ubuntu base image.

The aosp wrapper is a simple wrapper to simplify invocation of the Docker image. The wrapper ensures that a volume mount is accessible and has valid permissions for the aosp user in the Docker image (this unfortunately requires sudo). It also forwards an ssh-agent in to the Docker container so that private git repositories can be accessed if needed.

The intention is to use aosp to prefix all commands one would run in the Docker container. For example to run repo sync in the Docker container:

aosp repo sync -j2

The aosp wrapper doesn't work well with setting up environments, but with some bash magic, this can be side stepped with short little scripts. See tests/build-kitkat.sh for an example of a complete fetch and build of AOSP.
