无法找到部署为云运行服务的Spring应用程序

Question

我按照指南(https://cloud.google.com/debugger/docs/setup/java#cloud-run)设置了云运行服务的云调试器。一切看起来都应该正常。但是调试器UI告诉我它找不到任何应用程序。

​

​

然而，我做了文档中提到的所有事情。

• 源代码在源代码库中
• 基于master push的云构建触发器
• 我下载cdbg-java-agent.so
• 我使用-agentpath选项运行java应用程序。
• 云运行服务正在通过cloudbuild.yaml部署。
• 云运行服务健康启动并正常工作。

但是，正如您在屏幕截图中看到的那样，在成功部署之后找不到我的应用程序。

下面是我的配置的一些细节：

• 弹簧启动v2.4.2
• 科特林1.4.21

这是我的Dockerfile

FROM gradle:6.7.0-jdk14 as build
USER root
WORKDIR /dist
ADD . /dist
RUN gradle assemble

FROM alpine as agent
USER root
WORKDIR /agent
RUN wget -qO- https://storage.googleapis.com/cloud-debugger/compute-java/debian-wheezy/cdbg_java_agent_gce.tar.gz | tar xvz

FROM openjdk:14-slim
WORKDIR /app
COPY --from=agent /agent/cdbg_java_agent.so agent.so
COPY --from=build /dist/build/libs/user-service.jar app.jar
EXPOSE 8080
CMD ["java", "-agentpath:/app/agent.so", "-Dcom.google.cdbg.breakpoints.enable_canary=false", "-jar", "app.jar"]

下面是停靠程序的生成输出

Welcome to Gradle 6.7!

Here are the highlights of this release:
 - File system watching is ready for production use
 - Declare the version of Java your build requires
 - Java 15 support

正如前面提到的部署云运行服务一样，容器运行良好。所以我想不出该怎么做才能做到这一点。我希望这里有人能帮我

我还添加了我的cloudbuild.yaml，以防与此相关

Answer 1

如果您查看压缩代理文件中的内容，您会注意到其中有几个文件名为：

1. cdbg_java_agent.so
2. cdbg_java_agent_internals.jar
3. version.txt

您会遇到这个问题，因为您错过了将internals.jar文件复制到/app dir。共享对象文件有一个依赖项，这可以解释为什么指示用户为调试器创建一个单独的目录。

要在这种情况下修复它，请将丢失的文件添加到您的Dockerfile中，如下所示：

COPY --from=agent /agent/cdbg_java_agent.so agent.so
COPY --from=agent /agent/cdbg_java_agent_internals.jar cdbg_java_agent_internals.jar
COPY --from=build /dist/build/libs/user-service.jar app.jar

那就等大约吧。~5分钟后，你的服务就会出现在调试器上。注意，源代码不会出现自动，除非它位于Git上。为此，你必须手动选择源代码。
