# An image for building IREE in RBE's remmote execution environments.
# The parent image requires gcloud authorization to download (run
# `gcloud auth configure-docker`)

# Note that this doesn't reuse anything from our other docker images because it
# is based on Ubuntu 16.04, which is the only image that RBE provides toolchains
# for. There are also Ubuntu 18.04 images, but we'd have to construct all our
# own toolchains.
