# Linux RBE toolchain container. #
##################################

# Generates a Linux RBE toolchain container image for SkCMS.
#
# This container can be pushed to GCR via the //:push_rbe_container_skcms_linux rule.
#
# To debug this image:
#
#     # Build the container image.
#     $ bazel build //:rbe_container_skcms_linux
#
#     # Load the container.
#     $ docker load -i bazel-bin/rbe_container_skcms_linux_commit.tar
#     Loaded image: bazel-bin/default:rbe_container_skcms_linux
#
#     # Run the container.
#     $ docker run -it bazel/default:rbe_container_skcms_linux /bin/bash
