Android Open Source Project Docker Build Environment
Minimal build environment for AOSP with handy automation wrapper scripts.
Developers can use the Docker image to build directly while running the distribution of choice, without having to worry about breaking the delicate AOSP build due to package updates as is sometimes common on bleeding edge rolling distributions like Arch Linux.
Production build servers and integration test servers should also use the same Docker image and environment. This eliminates most surprise breakages by by empowering developers and production builds to use the exact same environment. The devs will catch the issues with build environment first.
This works well on Linux. Running this via
boot2docker (and friends) will
result in a very painful performacne hit due to VirtualBox's
folder service which works terrible for very large file shares like AOSP.
It might work, but consider yourself warned. If you're aware of another way to
get around this, send a pull request!
For the terribly impatient.
- Make a directory to work and go there.
- Export the current directory as the persistent file store for the
Run a self contained build script, which does:
- Attempts to fetch the
aospwrapper if not found locally.
- Runs the
aospwrapper with an extra argument for the docker binary and hints to the same script that when run later it's running in the docker container.
- The aosp wrapper then does it's magic which consists of fetching the docker image if not found and forms all the necessary docker run arguments seamlessly.
- The docker container runs the other half the build script which initializes the repo, fetches all source code, and builds.
In parallel you are expected to be drinking because I save you some time.

This takes about 2 hours to download and build on i5-2500k with 100Mb/s network connection.

How it Works
The Dockerfile contains the minimal packages necessary to build Android based on the main Ubuntu base image.
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
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-nougat.sh for an example of a complete fetch and build of AOSP.
There are some known issues with using Docker Toolbox on macOS and current virtualization technologies resulting in unusual user ID assignments and very poor performing virtualization file sharing implementations with things like VirtualBox. It's recommended to run this image completely in a virtual machine with enough space to fit the entire build (80GB+) as opposed to mapping the build to the local macOS file system via VirtualBox or similar.
