Dockerfile

# This Dockerfile is used to create a container around gcc9 and bazel for
# building the CEL C++ library on GitHub.
#
# To update a new version of this container, use gcloud. You may need to run
# `gcloud auth login` and `gcloud auth configure-docker` first.
#
# Note, if you need to run docker using `sudo` use the following commands
# instead:
#
#     sudo gcloud auth login --no-launch-browser
#     sudo gcloud auth configure-docker
#
# Run the following command from the root of the CEL repository:
#
#     gcloud builds submit --region=us -t gcr.io/cel-analysis/gcc9 .
#
# Once complete get the sha256 digest from the output using the following
# command:
#
#     gcloud artifacts versions list --package=gcc9 --repository=gcr.io \
#       --location=us
#
# The cloudbuild.yaml file must be updated to use the new digest like so:
#
#     - name: 'gcr.io/cel-analysis/gcc9@<SHA256>'
FROM gcc:9

# Install Bazel prerequesites and required tools.
