-

-# distributed with CentOS (notably CMake) are too old to build
-# `cpp-cmakefiles`. In these instructions, we use `cmake3` obtained from
-# [Software Collections](https://www.softwarecollections.org/).
-

-RUN rpm -Uvh https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm
-RUN yum install -y centos-release-scl

-

-RUN tar -xf cares-1_15_0.tar.gz

-RUN ./buildconf && ./configure && make -j $(nproc)
-RUN make install
-RUN ldconfig
-# ```
-
-# #### gRPC
-
-# Can be manually installed using:
-
-# ```bash
-WORKDIR /var/tmp/build
-RUN wget -q https://github.com/grpc/grpc/archive/v1.22.0.tar.gz

-RUN make -j $(nproc)
-RUN make install
-RUN ldconfig
-# ```
-
-FROM devtools AS install
-
-# #### googleapis
-
-# Finally we can install `googleapis`.

-RUN cmake -H. -Bcmake-out

-## [START INSTALL.md]
-
-# Install the minimal development tools:
-
-# ```bash
-RUN zypper refresh && \
-    zypper install --allow-downgrade -y cmake gcc gcc-c++ git gzip \
-        libcurl-devel libopenssl-devel make tar wget
-# ```
-
-# #### Protobuf
-
-# OpenSUSE Leap includes a package for protobuf-2.6, but this is too old to
-# support the Google Cloud Platform proto files, or to support gRPC for that
-# matter. Manually install protobuf:
-
-# ```bash
-WORKDIR /var/tmp/build
-RUN wget -q https://github.com/google/protobuf/archive/v3.9.0.tar.gz
-RUN tar -xf v3.9.0.tar.gz
-WORKDIR /var/tmp/build/protobuf-3.9.0/cmake
-RUN cmake \
-        -DCMAKE_BUILD_TYPE=Release \
-        -DBUILD_SHARED_LIBS=yes \
-        -Dprotobuf_BUILD_TESTS=OFF \
-        -H. -Bcmake-out
-RUN cmake --build cmake-out --target install -- -j $(nproc)
-RUN ldconfig
-# ```
-
-# #### c-ares
-
-# Recent versions of gRPC require c-ares >= 1.11, while OpenSUSE Leap
-# distributes c-ares-1.9. We need some additional development tools to compile
-# this library:
-
-# ```bash
-RUN zypper refresh && \
-    zypper install -y automake libtool
-# ```
-
-# Manually install a newer version:
-
-# ```bash
-WORKDIR /var/tmp/build
-RUN wget -q https://github.com/c-ares/c-ares/archive/cares-1_15_0.tar.gz
-RUN tar -xf cares-1_15_0.tar.gz
-WORKDIR /var/tmp/build/c-ares-cares-1_15_0
-RUN ./buildconf && ./configure && make -j $(nproc)
-RUN make install
-RUN ldconfig
-# ```
-
-# #### gRPC
-
-# The gRPC Makefile uses `which` to determine whether the compiler is available.
-# Install this command for the extremely rare case where it may be missing from
-# your workstation or build server:
-
-# ```bash
-RUN zypper refresh && \
-    zypper install -y which
-# ```
-
-# Then gRPC can be manually installed using:
-
-# ```bash
-WORKDIR /var/tmp/build
-RUN wget -q https://github.com/grpc/grpc/archive/v1.22.0.tar.gz
-RUN tar -xf v1.22.0.tar.gz
