| # 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. |
| # |
| # 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 |
| # |
| # 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 |
