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 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.

Quickstart
|
|
|
|
|
----------
|
|
|
|
|
|
|
|
|
|
For the terribly impatient.
|
|
|
|
|
|
|
|
|
|
1. Make a directory to work and go there.
|
|
|
|
|
2. Export the current directory as the persistent file store for the `aosp`
|
|
|
|
|
wrapper.
|
|
|
|
|
3. Run a self contained build script, which does:
|
|
|
|
|
1. Attempts to fetch the `aosp` wrapper if not found locally.
|
|
|
|
|
2. Runs the `aosp` wrapper 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.
|
|
|
|
|
3. 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.
|
|
|
|
|
4. The docker container runs the other half the build script which
|
|
|
|
|
initializes the repo, fetches all source code, and builds.
|
|
|
|
|
5. In parallel you are expected to be drinking because I save you some time.

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.
