仅在 8080 上运行的 Spring Boot docker？

Posted 2023-02-27

【中文标题】仅在 8080 上运行的 Spring Boot docker？

【英文标题】：Spring boot docker running on 8080 only?

【发布时间】：2021-05-17 10:53:55

【问题描述】：

我已经在 docker 上部署了我的 spring boot 应用程序，但是当我尝试运行它时，它只在 8080 端口上运行，而不是任何其他端口，即来自日志的 3000 我能够推断它与内部 tomcat 有关监听 8080 端口。谁能告诉我里面发生了什么？

以下是我在 8080 上运行时的日志

下面是我要运行的命令

docker run -p 3000:3000 ebiproject

【参考方案1】：

我认为您在这里遗漏了重要的概念。 8080 是 Spring Boot 应用程序的默认端口。但是，在您的 docker 网络配置中，您映射了 3000 -> 3000 这是错误的。

相反，您应该进行如下配置： docker run -p 3000:8080 ebiproject

【讨论】：

我是从可用的教程中做到的，你能解释一下区别

您的容器化 spring-boot 应用程序运行在 docker 容器之上。并且您的 docker 容器在 docker 主机（可能是您的机器）上运行。如果不指定打开哪些端口，docker 默认禁用所有访问。这意味着您的应用程序将在容器的 8080 端口上提供服务。但是，同样，由于您没有公开容器的 8080 端口，它将无法访问。 -p 3000:8080 使您能够将 docker 主机的 3000 端口映射到容器（spring-boot 应用程序运行的地方）的 8080 端口。
