Several contributors have been asking me how to reproduce the CI environment locally. This is the last step towards making that work out-of-the-box. Basically, just run `libcxx/utils/ci/run-buildbot-container` and you're good to go. Differential Revision: https://reviews.llvm.org/D97782

# This Dockerfile describes the base image used to run the various libc++
|
|
# build bots. By default, the image runs the Buildkite Agent, however one
|
|
# can also just start the image with a shell to debug CI failures.
|
|
#
|
|
# To start a Buildkite Agent, run it as:
|
|
# $ docker run --env-file secrets.env -it $(docker build -q .)
|
|
#
|
|
# The environment variables in `secrets.env` must be replaced by the actual
|
|
# tokens for this to work. These should obviously never be checked in.
|
|
#
|
|
# If you're only looking to run the Docker image locally for debugging a
|
|
# build bot, see the `run-buildbot-container` script located in this directory.
|
|
#
|
|
# A pre-built version of this image is maintained on DockerHub as ldionne/libcxx-builder.
|
|
# To update the image, rebuild it and push it to ldionne/libcxx-builder (which
|
|
# will obviously only work if you have permission to do so).
|
|
#
|
|
# $ docker build -t ldionne/libcxx-builder .
|
|
# $ docker push ldionne/libcxx-builder
