运行 Spring 在 Azure Functions 上启动本机应用程序：权限被拒绝 server.port：80
Running Spring Boot Native Application on Azure Functions: Permission denied with server.port: 80
我创建了一个简单的 Spring 引导应用程序并使用 Spring 本机 gradle bootBuildImage 编译了它。我将 docker 容器上传到私有注册表并将其部署到 Microsoft Azure Functions。访问该函数将正确启动 docker 容器内的 Spring 启动应用程序。但它崩溃并出现以下异常：

关于日志，Azure 从 docker 开始
docker run -d -p 7502:80...
第一个端口似乎是随机的。
完整的源代码可以在这里找到：https://github.com/lesestunden/buchschrank-backend
有人知道出了什么问题吗？
非常感谢！
您的应用程序应侦听非特权端口 (> 1024)。
创建的容器无法使用 privileged port. The bootBuildImage task creates and runs images utilizing buildpacks (for runtime paketobuildpacks/run:tiny-cnb)，容器中的应用程序未 运行 作为根。因此你不能监听低于 1024 的端口。
Spring 引导使用 paketo-buildpacks，其中有一些安全强化措施
The stack images are run as a dedicated non-root user when building
and running applications.
解决方案是使用大于 1024 的端口（例如 8080）并按照此答案配置端口：

关于日志，Azure 从 docker 开始
docker run -d -p 7502:80...
第一个端口似乎是随机的。

有人知道出了什么问题吗？
非常感谢！
您的应用程序应侦听非特权端口 (> 1024)。
创建的容器无法使用 privileged port. The bootBuildImage task creates and runs images utilizing buildpacks (for runtime paketobuildpacks/run:tiny-cnb)，容器中的应用程序未 运行 作为根。因此你不能监听低于 1024 的端口。
Spring 引导使用 paketo-buildpacks，其中有一些安全强化措施
The stack images are run as a dedicated non-root user when building and running applications.
解决方案是使用大于 1024 的端口（例如 8080）并按照此答案配置端口：
