Easy builds for Facebook projects
This is a Python 2.6+ library designed to simplify continuous-integration (and other builds) of Facebook projects.
For external Travis builds, the entry point is travis_docker_build.sh.
Using Docker to reproduce a CI build
If you are debugging or enhancing a CI build, you will want to do so from host or virtual machine that can run a reasonably modern version of Docker:
./make_docker_context.py --help # See available options for OS & compiler
# Tiny wrapper that starts a Travis-like build with compile caching:
os_image=ubuntu:18.04 \
gcc_version=7 \
make_parallelism=2 \
travis_cache_dir=~/travis_ccache \
./travis_docker_build.sh &> build_at_$(date +'%Y%m%d_%H%M%S').log
IMPORTANT: Read fbcode_builder/README.docker before diving in!
Setting travis_cache_dir turns on ccache,
saving a fresh copy of ccache.tgz after every build. This will invalidate
Docker's layer cache, foring it to rebuild starting right after OS package
setup, but the builds will be fast because all the compiles will be cached.
To iterate without invalidating the Docker layer cache, just cd /tmp/docker-context-* and interact with the Dockerfile normally. Note
that the docker-context-* dirs preserve a copy of ccache.tgz as they
first used it.
What to read next
The *.py files are fairly well-documented. You might want to peruse them in this order:
- shell_quoting.py
- fbcode_builder.py
- docker_builder.py
- make_docker_context.py
As far as runs on Travis go, the control flow is:
- .travis.yml calls
- travis_docker_build.sh calls
- docker_build_with_ccache.sh
This library also has an (unpublished) component targeting Facebook's internal continuous-integration platform using the same build-step DSL.
Contributing
Please follow the ambient style (or PEP-8), and keep the code Python 2.6
compatible -- since fbcode_builder's only dependency is Docker, we want to
allow building projects on even fairly ancient base systems. We also wish
to be compatible with Python 3, and would appreciate it if you kept that
in mind while making changes also.
