+FROM opensuse/leap:latest AS devtools
+
+## [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 $(nproc)
+RUN make install
+RUN ldconfig
+# ```
+
+# #### gRPC
+
+# The gRPC Makefile uses `which` to determine whether the compiler is available.
+# Install this command for the extremely rare case where it may be missing from
+# your workstation or build server:
+
+# ```bash
+RUN zypper refresh && \
+    zypper install -y which
+# ```
+
+# Then gRPC can be manually installed using:
+
+# ```bash
+WORKDIR /var/tmp/build
+RUN wget -q https://github.com/grpc/grpc/archive/v1.22.0.tar.gz
+RUN tar -xf v1.22.0.tar.gz
+WORKDIR /var/tmp/build/grpc-1.22.0
+ENV PKG_CONFIG_PATH=/usr/local/lib/pkgconfig:/usr/local/lib64/pkgconfig
+ENV LD_LIBRARY_PATH=/usr/local/lib:/usr/local/lib64
+ENV PATH=/usr/local/bin:${PATH}
+RUN make -j $(nproc)
+RUN make install
+RUN ldconfig
+# ```
+
+FROM devtools AS install
+
+# #### googleapis
+
+# We can now compile and install `googleapis`.
+
+# ```bash
+WORKDIR /home/build/cpp-cmakefiles
+COPY . /home/build/cpp-cmakefiles
+RUN cmake -H. -Bcmake-out
+RUN cmake --build cmake-out -- -j $(nproc)
+WORKDIR /home/build/cpp-cmakefiles/cmake-out
+RUN cmake --build . --target install
+# ```
+
+## [END INSTALL.md]

+# Verify that the installed files are actually usable
