我已经为我的Spring Boot项目从GitHub设置了到Cloud Run的连续部署，虽然它在Cloud Build中成功构建，但当我转到Cloud Run时，我在创建修订版下遇到了以下错误：The user-provided container failed to start and listen on the port defined provided by the PORT=8080 environment variable.
当我转到日志时，我看到以下错误：

Dockerfile如下(查看构建日志，其中的所有命令都已成功完成(：
FROM openjdk:17-jdk-alpine
RUN addgroup -S spring && adduser -S spring -G spring
USER spring:spring
COPY . /app
ENTRYPOINT [ "java","-jar","/app/target/educity-manager-0.0.1-SNAPSHOT.jar" ]
我已经读到Cloud Run默认公开端口8080，但为了安全起见，我将server.port=${PORT:8080}放在了application.properties文件中(但这似乎没有任何区别(。
我过去也遇到过类似的问题。通常，我可以通过以下方式解决此问题：
- 指定应用程序本身中的端口(如您在文章中所述(，以及
- 在我的dockerfile中暴露所需的端口，例如
EXPOSE 8080
天哪，我做到了。经过整整两天的挖掘，我意识到，因为我是通过github完成的，所以我的.gitignore文件不包括包含jar文件的/target文件夹，所以Cloud Build从未得到Dockerfile中提到的jar文件。
我要哭一场，然后去酒吧。
