Bazel无法在图像中安装_pkgs

Question

我正在尝试添加一些软件包来分散Debian-11 python image（ gcr.io/distroless/python3-debian11:debug ）。 Bazel Build成功了，但是当我运行生成图像时，Debian Pacakges不存在。 如果您想克隆进行快速测试，则是项目链接git克隆https://github.com/bhanukiranchaluvadi/getting-started-with-with-bazel.git.git.git。这是我的项目结构

如果我将块与image_tar =“@debian11-slim // image>“ “”并注释image_tar =“@python3-debian11 // image” < /代码>。生成的图像看起来不错，所有软件包都按预期安装。它仅与python3-debian11分散图像

，看起来它正在安装下载的软件包文件夹和使用DPKG解开包装。但是分散的Python图像中没有DPKG/APT安装。这是包装未安装的原因吗？如果是这样，为什么bazel构建//...没有失败？

调试： 如果您想调试产生的图像

docker run -it --rm --entrypoint sh distroless/ros2-debian11:latest
# example library from libfmt
ls /usr/lib/x86_64-linux-gnu/libfmt.so.7.1.3

Answer 1

install_pkgs启动容器并下载所有必要的软件包。由于干扰软件包没有安装在其中的包装。安装程序包可能会失败。
