# An image for building IREE using CMake and testing IREE with SwiftShader
# Vulkan implementation.

# Build using:
# docker build --tag gcr.io/iree-oss/cmake-swiftshader \
#   build_tools/docker/cmake_swiftshader/

# Run interactively using the following, where IREE_WORKDIR is the path to your
# local dev environment:
# docker run -it --rm --entrypoint bash \
#   --volume "${IREE_WORKDIR?}:/usr/src/iree/" \
#   --gpus all \
#   gcr.io/iree-oss/cmake-swiftshader

# Set up the image and working directory by inheriting the base
# CMake configuration.
