-
-## [START INSTALL.md]
-
-# First install the development tools and OpenSSL. The development tools
-# 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/).
-
-# ```bash
-RUN rpm -Uvh https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm
-RUN yum install -y centos-release-scl
-RUN yum-config-manager --enable rhel-server-rhscl-7-rpms
-RUN yum makecache && \

-RUN ln -sf /usr/bin/cmake3 /usr/bin/cmake && ln -sf /usr/bin/ctest3 /usr/bin/ctest
-# ```
-
-# #### Protobuf
-
-# Likewise, 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

-        -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 CentOS-7
-# distributes c-ares-1.10. Manually install a newer version:
-
-# ```bash
-WORKDIR /var/tmp/build

-RUN ./buildconf && ./configure && make -j $(nproc)
-RUN make install
-RUN ldconfig
-# ```
-
-# #### gRPC
-
-# Can be manually installed using:
-
-# ```bash
-WORKDIR /var/tmp/build

-
-# #### Protobuf
-
-# OpenSUSE Leap includes a package for protobuf-2.6, but this is too old to

-# matter. Manually install protobuf:
-
-# ```bash
-WORKDIR /var/tmp/build

-# ```
-
-# #### 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
