java - 如何在 Cloud Foundry 中将自定义 C 共享库与 Java 应用程序捆绑在一起？

Question

我之前已经在 Cloud Foundry 中成功部署了一个 Java 应用程序。然而，现在开发人员已经添加了一个从 C 编译的共享库。我已经将 .so 添加到 .zip 文件(我正在使用通用打包程序并部署到云Foundry by zip 文件)并确保 .so 是可执行的。但是，当我部署时出现错误:

2016-12-23T14:39:01.013+00:00 [STG/0] [OUT] -----> Java Buildpack Version: eba4df6 | git://github.com/cloudfoundry/java-buildpack.git#eba4df6
2016-12-23T14:39:01.017+00:00 [STG/0] [ERR] [Buildpack] ERROR Compile failed with exception #<RuntimeError: No container can run this application.

所以我的理解是我需要从 Java Buildpack 创建一个 Custom Buildpack。但是，此时我被代码困住了: https://github.com/ONSdigital/java-buildpack/blob/master/bin/compile#L28

# Adding crf tagger library
status "Adding crf tagger support"
cp $bp_dir/parsers/src/main/resources/libbackend.so $build_dir/vendor/

# update the PATH
status "Building runtime environment"
mkdir -p $build_dir/.profile.d
echo "export PATH=\"$HOME/bin:\$HOME/vendor/:\$PATH\";" > $build_dir/.profile.d/crftagger.sh
echo "export LD_LIBRARY_PATH=\"\$HOME/vendor/\";" >> $build_dir/.profile.d/crftagger.sh

据我所知，我只需要修改 compile 阶段。我需要做什么才能复制 .so 并成功运行 Buildpack。

请看这个https://docs.cloudfoundry.org/devguide/deploy-apps/deploy-app.html#profile

您需要的运行前 Hook 。我无法为您提供更多详细信息，因为您没有提供足够的信息(项目结构，您的根目录中是否有 .profile 等)。

如果您需要添加共享库，请尝试使用 attr_reader :additional_libraries https://github.com/cloudfoundry/java-buildpack/blob/master/docs/extending-droplet.md
