如何在多阶段Docker构建的各个阶段之间复制库文件,同时保留符号链接?

COPY --from= 从第一阶段复制库文件的命令 /usr/local/lib/libproto* 到当前图像的。

我看到的问题是,第一个映像包含从通用库文件名到特定版本文件名的符号链接。AFAIK这是Debian和许多其他Linux系统中的常见做法。码头工人 COPY apt-get 命令 ldconfig: /usr/local/lib/libprotobuf.so.17 is not a symbolic link .

#Compile any tools we cannot install from packages
FROM gcc:7 as builder

RUN \
  apt-get -y update && \
  apt-get -y install \
    clang \
    libc++-dev \
    libgflags-dev \
    libgtest-dev
RUN \
  # Protocol Buffer & gRPC
  # install protobuf first, then grpc
  git clone -b $(curl -L https://grpc.io/release) \
      https://github.com/grpc/grpc /var/local/git/grpc && \
    cd /var/local/git/grpc && \
    git submodule update --init && \
    echo "--- installing protobuf ---" && \
    cd third_party/protobuf && \
    ./autogen.sh && ./configure --enable-shared && \
    make -j$(nproc) && make install && make clean && ldconfig && \
    echo "--- installing grpc ---" && \
    cd /var/local/git/grpc && \
    make -j$(nproc) && make install && make clean && ldconfig

如您所见,我正在尝试将gRPC和protocolbuffer的最新版本添加到基于Debian的运行时映像中。
