如何将docker-compose.yml翻译为Django的Dockerrun.aws.json

Question

我按照https://docs.docker.com/compose/django/上的说明获取基本的dockerized django应用程序.我可以在本地运行它而没有问题,但我无法使用Elastic Beanstalk将其部署到AWS.在这里阅读之后,我想我需要将docker-compose.yml翻译成Dockerrun.aws.json才能工作.

原始的docker-compose.yml是

version: '2'
services:
  db:
    image: postgres
  web:
    build: .
    command: python manage.py runserver 0.0.0.0:8000
    volumes:
      - .:/code
    ports:
      - "8000:8000"
    depends_on:
      - db

这是我到目前为止翻译的内容

{
  "AWSEBDockerrunVersion": 2,
  "volumes": [
    {
      "name": "db"
    },
    {
      "name": "web"
    }
  ],
  "containerDefinitions": [
    {
      "name": "db",
      "image": "postgres",
      "essential": true,
      "memory": 256,
      "mountPoints": [
        {
          "sourceVolume": "db"
          "containerPath": "/var/app/current/db"
        }
      ]
    },
    {
      "name": "web",
      "image": "web",
      "essential": true,
      "memory": 256,
      "mountPoints": [
        {
          "sourceVolume": "web"
          "containerPath": "/var/app/current/web"
        }
      ],
      "portMappings": [
       {
         "hostPort": 8000,
         "containerPort": 8000
       }
     ],
     "links": [
        "db"
      ],
      "command": "python manage.py runserver 0.0.0.0:8000"
    }
  ]
}

但它不起作用.我究竟做错了什么？

我很难弄清楚这种Dockerrun格式的来龙去脉.查看容器转换:"转换docker-compose,ECS和Marathon配置"......它可以节省生命.以下是为您的示例输出的内容:

{
    "containerDefinitions": [
        {
            "essential": true,
            "image": "postgres",
            "name": "db"
        },
        {
            "command": [
                "python",
                "manage.py",
                "runserver",
                "0.0.0.0:8000"
            ],
            "essential": true,
            "mountPoints": [
                {
                    "containerPath": "/code",
                    "sourceVolume": "_"
                }
            ],
            "name": "web",
            "portMappings": [
                {
                    "containerPort": 8000,
                    "hostPort": 8000
                }
            ]
        }
    ],
    "family": "",
    "volumes": [
        {
            "host": {
                "sourcePath": "."
            },
            "name": "_"
        }
    ]
}
Container web is missing required parameter "image".
Container web is missing required parameter "memory".
Container db is missing required parameter "memory".

也就是说,在这种新格式中,您必须告诉它分配每个容器的内存量.此外,您需要提供图像 - 没有选项可以构建.正如评论中提到的,您希望构建并推送到DockerHub或ECR,然后将其提供给该位置:例如,[org name]/[repo]:latest在Dockerhub上,或ECR的URL.但container-transform确实在mountPoints和volumes你-这是惊人的.
