| # 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 |
