spring-boot - 在 Azure Functions : Permission denied with server. 端口上运行 Spring Boot native 应用程序:80

标签 spring-boot azure docker azure-functions spring-native

我创建了一个简单的 Spring Boot 应用程序，并使用 Spring Native gradle bootBuildImage 对其进行编译。我将 docker 容器上传到私有(private)注册表并将其部署到 Microsoft Azure Function。访问该函数将正确启动 docker 容器内的 Spring Boot 应用程序。但它崩溃并出现以下异常:

关于日志，Azure 启动 docker

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!

最佳答案

您的应用程序应监听非特权端口 (> 1024)。

创建的容器无法使用privileged port 。 bootBuildImage 任务利用构建包创建并运行镜像(对于运行时 paketobuildpacks/run:tiny-cnb )，容器中的应用程序不会以 root 身份运行。因此您无法监听低于 1024 的端口。

Spring boot使用paketo-buildpacks ，其中有一些安全强化

The stack images are run as a dedicated non-root user when building and running applications.

参见paketo documentation
