Docker：撰写文件与 Amazon ECS 不兼容

Question

我正在尝试在 AWS ECS 中部署我的 docker 映像。我已经创建了 ECR 存储库并完成了所有必需的步骤，直到将映像推送到 ECS。

我的 docker-compose.yaml 看起来像这样

version: '3'

services:

  djangoapp:
    image: xxxxx.dkr.ecr.ca-central-1.amazonaws.com/abc:latest #uri after pushing the image
    build: .
    volumes:
      - .:/opt/services/djangoapp/src
      - static_volume:/opt/services/djangoapp/static  # <-- bind the static volume
      - media_volume:/opt/services/djangoapp/media  # <-- bind the media volume
    networks:
      - nginx_network
      - database1_network
    depends_on:
      - database1

      
  nginx:
    image: nginx:1.13
    ports:
      - 80:5000
    volumes:
      - ./config/nginx/conf.d:/etc/nginx/conf.d
      - static_volume:/opt/services/djangoapp/static  # <-- bind the static volume
      - media_volume:/opt/services/djangoapp/media  # <-- bind the media volume
    depends_on:
      - djangoapp
    networks:
      - nginx_network

  database1:
    image: postgres:10
    env_file:
      - config/db/database1_env
    networks:
      - database1_network
    volumes:
      - database1_volume:/var/lib/postgresql/data

networks:
  nginx_network:
    driver: bridge
  database1_network:
    driver: bridge

volumes:
  database1_volume:
  static_volume:  # <-- declare the static volume
  media_volume:  # <-- declare the media volume

我正在尝试运行命令：

docker ecs compose  -n abc up 

我收到以下错误：

WARN[0000] services.build: unsupported attribute        
WARN[0000] services.volumes: unsupported attribute      
ERRO[0000] published port can't be set to a distinct value than container port: incompatible attribute 
WARN[0000] services.volumes: unsupported attribute

WARN[0000] networks.driver: unsupported attribute       
WARN[0000] networks.driver: unsupported attribute       
compose file is incompatible with Amazon ECS

我正在使用最新版本的 docker，即 19.03.08 和最新的 aws-cli/2.0.39。

我遇到了同样的麻烦，我可以通过删除docker-compose.yaml 中除image 之外的所有属性来解决此问题。

在image 属性下的djangoapp 服务中，将值设置为带有注释“推送图像后的URI”的URI。大概这是一个本地构建的 docker 镜像djangoapp 的 URI，该镜像被推送到 ECR 存储库。

由于您已经构建并将 djangoapp 图像推送到 ECR，只需保留 image 属性并注释掉来自docker-compose.yaml 的错误消息中列出的所有其他属性：

1. 构建
2. 卷
3. ...

就我而言，它有所帮助。

Docker 决定不允许这样做。这就是他们在 Slack convo 上所说的："We decided to not support this as this would only apply to ingress traffic, not service-to-service, which would be both confusing and inconsistent with local development"。
