# Docker file for building gRPC Raspbian binaries

# TODO(https://github.com/grpc/grpc/issues/19199): Move off of this base image.
FROM quay.io/grpc/raspbian_armv7

# Place any extra build instructions between these commands
# Recommend modifying upstream docker image (quay.io/grpc/raspbian_armv7)
# for build steps because running them under QEMU is very slow
