Docker 将依赖项传递给 AWS Elastic Beanstalk

Question

在 Docker Compose 中，镜像之间的通信使用的是服务名称。例如：

• 应在docker-compose.yml 文件中定义

    depends_on:
            - database

这个依赖可以用在：

"server=database;uid=root;pwd=root;database=database"

主要是docker-compose.yml文件中定义的服务名称表示主机名。我使用 AWS Elastic Beanstalk 将我的微服务架构部署到云端，当我运行由 container-transform 生成的 Dockerrun.aws.json 本地运行时，此依赖项不可用。

我的问题是。我做错了吗？

WS Elastic Beanstalk 是否提供 Docker Compose 中的依赖项？

在我的真实例子中。 docker-compose.yml 的部分内容

    version: '3'

services:
  rabbitmq: # login guest:guest
    image: rabbitmq:3-management
    hostname: "rabbitmq"
    labels:
      NAME: "rabbitmq"
    ports:
    - "4369:4369"
    - "5671:5671"
    - "5672:5672"
    - "25672:25672"
    - "15671:15671"
    - "15672:15672"
  xms.accounts:
    image: ditrikss/accounts
    build: ./Microservices/Account/Xms
    restart: always
    ports:
      - 6001:80
    depends_on:
        - xdb.accounts
        - rabbitmq
    environment:
        - ASPNETCORE_ENVIRONMENT=Production
  xdb.accounts:
    image: mysql/mysql-server
    restart: always
    environment:
      MYSQL_DATABASE: 'xdb_accounts'
      MYSQL_USER: 'root'
      MYSQL_PASSWORD: 'root'
      MYSQL_ROOT_PASSWORD: 'root'
    ports:
      - '6002:3306'
    volumes:
      - "./Databases/Scripts/xdb_Accounts/Create/1_accounts.sql:/docker-entrypoint-initdb.d/1.sql"
      - "./Databases/Scripts/xdb_Accounts/Create/2_passwords.sql:/docker-entrypoint-initdb.d/2.sql"
      - "./Databases/Scripts/xdb_Accounts/Create/3_channel_features.sql:/docker-entrypoint-initdb.d/3.sql"
      - "./Databases/Scripts/xdb_Accounts/Create/4_streaming_features.sql:/docker-entrypoint-initdb.d/4.sql"

以及Dockerrun.aws.json文件的反映代码

根据Dockerrun.aws.json v2 reference，您应该在Dockerrun.aws.json 文件中添加links 部分：

链接的定义：

要链接到的容器列表。链接的容器可以发现 彼此安全通信。

示例用法：

{
    "name": "nginx-proxy",
    "image": "nginx",
    "essential": true,
    "memory": 128,
    "portMappings": [{
        "hostPort": 80,
        "containerPort": 80
    }],
    "links": [
        "php-app"
    ],
    "mountPoints": [
        {
          "sourceVolume": "php-app",
          "containerPath": "/var/www/html",
          "readOnly": true
        }
    ]
}
