# This file defines the image we use for Linux testing using Github Actions.
# From the root of the monorepo, this image can be built with:
#
#   $ docker build --file libcxx/utils/ci/docker/linux-builder.dockerfile \
#                  --build-arg BASE_IMAGE_VERSION=<sha>                   \
#                  --build-arg GITHUB_RUNNER_VERSION=<version> .
#
# This image also gets built on every push to `main` that modifies these Docker
# files, and can be found at ghcr.io/llvm/libcxx-linux-builder.
