The compiler support policy mentions that we support Clang 11 and 12, so we should test those. We already test on Clang 12, but I'll add testers for Clang 11 once the new Docker image is in use on all the builders.

# 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> -it $(docker build -q .)
|
|
#
|
|
# The environment variables in `<secrets>` should be the ones necessary
|
|
# to run a BuildKite agent.
|
|
#
|
|
# 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
