[libc++] Add a utility script to run the Docker image used by builders
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

# The environment variables in `secrets.env` must be replaced by the actual

# tokens for this to work. These should obviously never be checked in.

# To start a shell in the Docker image, use:
|

# $ docker run -it --volume "$(git rev-parse --show-toplevel):/llvm" --workdir "/llvm" $(docker build -q .) bash
|

#
|

# This will fire up the Docker container and mount the root of the monorepo
|

# as /llvm in the container. Be careful, the state in /llvm is shared between
|

# the container and the host machine.
|

|

# Finally, a pre-built version of this image is available on DockerHub as
|

# ldionne/libcxx-builder. To use the pre-built version of the image, use
|
||||
#
|
||||
# $ docker pull ldionne/libcxx-builder
|
||||
# $ docker run -it <options> ldionne/libcxx-builder
|
||||
# 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).
