【中文标题】带有 docker 应用程序的 AWS Elastic Beanstalk 返回 502

【英文标题】：AWS Elastic Beanstalk with docker application returns 502

【发布时间】：2021-01-17 12:25:19

【问题描述】：

我用 docker 创建了一个 SPRING-BOOT 应用程序，我正在将此映像部署到 Elastic-beanstalk，一切顺利，通过日志，应用程序启动，但随后访问 ulr，我得到一个 503，我试了好几样，谁能给个意见？

我的 Dockerrun 文件：

    "AWSEBDockerrunVersion": "2",
    "containerDefinitions": [
        
            "essential": true,
            "image": "187190575110.dkr.ecr.us-east-1.amazonaws.com/kroton-app:$TAG",
            "memory": 512,
            "memoryReservation": 256,
            "mountPoints": [],
            "name": "kroton-app",
            "portMappings": [

                    "hostPort": "80"
                
            ]
        
    ]

【问题讨论】：

如果你 ssh 进入实例，容器会运行吗？你可以运行sudo docker ps。检查暴露的端口，直接 curl 容器看应用是否在 localhost 上运行。

好的，我将它插入实例并在端口上运行 docker ps 和 Curl，将上面的结果添加为 SSH 响应

【参考方案1】：

您的新输出显示您正在使用端口 8080：

0.0.0.0:8080->8080/tcp

您的Dockerrun 与这些端口不匹配：

            "portMappings": [
                
                    "containerPort": "8000",
                    "hostPort": "80"
                

所以不知何故，您在 Dockerrun 和实际 docker 运行时使用了不同的端口。

也许不需要在您的Dokerfile 中使用EXPOSE 8080。

【讨论】：

对不起，我在我的 Dockerrun.aws.json 中编辑了这个端口，但不工作。

【参考方案2】：

您将在 Dockerfile 上公开端口 8080，并在 Dockerrun.aws.json 上映射 8000。我相信这是真正的问题。为了解决，你可以在镜像上暴露8000端口，部署后尝试访问the endpoint with the port。

你能尝试用这个Dockerfile 构建一个镜像吗？

您是否公开了负载均衡器上关联的安全组上的端口？

我没有做任何关于负载平衡的事情，你有我如何验证这一点的例子吗？
