问题描述

我的码头工人撰写文件:

version: "2"
services:
  app:
    build:
      # Build an image from the Dockerfile in the current directory
      context: .
    ports:
      - 5000:5000
    environment:
      PORT: 5000
      NODE_ENV: production

和 docker-compose.override

version: "2"
networks:
    # This special network is configured so that the local metadata
    # service can bind to the specific IP address that ECS uses
    # in production
    credentials_network:
        driver: bridge
        ipam:
            config:
                - subnet: "169.254.170.0/24"
                  gateway: 169.254.170.1
services:
    # This container vends credentials to your containers
    ecs-local-endpoints:
        # The Amazon ECS Local Container Endpoints Docker Image
        image: amazon/amazon-ecs-local-container-endpoints
        volumes:
          # Mount /var/run so we can access docker.sock and talk to Docker
          - /var/run:/var/run
          # Mount the shared configuration directory, used by the AWS CLI and AWS SDKs
          # On Windows, this directory can be found at "%UserProfile%\.aws"
          - $HOME/.aws/:/home/.aws/
        environment:
          # define the home folder; credentials will be read from $HOME/.aws
          HOME: "/home"
          # You can change which AWS CLI Profile is used
          AWS_PROFILE: "default"
        networks:
            credentials_network:
                # This special IP address is recognized by the AWS SDKs and AWS CLI 
                ipv4_address: "169.254.170.2"
                
    # Here we reference the application container that we are testing
    # You can test multiple containers at a time, simply duplicate this section
    # and customize it for each container, and give it a unique IP in 'credentials_network'.
    app:
        logging:
              driver: awslogs
              options:
                awslogs-region: eu-west-3
                awslogs-group: sharingmonsterlog
        depends_on:
            - ecs-local-endpoints
        networks:
            credentials_network:
                ipv4_address: "169.254.170.3"
        environment:
          AWS_DEFAULT_REGION: "eu-west-3"
          AWS_CONTAINER_CREDENTIALS_RELATIVE_URI: "/creds"

我已使用 aws configure 命令将 AWS 凭证添加到我的 mac,并且凭证正确存储在 ~/.aws/credentials 中。

我正在使用 docker 2.2.0.4、docker-compose 1.25.4 和 docker-machine 0.16.2。

当我运行 docker-compose up 时,出现以下错误:

错误:刮板无法启动服务刮板:无法初始化日志记录驱动程序:NoCredentialProviders:链中没有有效的提供者。

已弃用。有关详细消息,请参阅 aws.Config.CredentialsChainVerboseErrors

错误:启动项目时遇到错误。

我相信这是因为我需要在 Docker 守护进程中设置 AWS 凭证,但我无法弄清楚这是如何在 macOS High Sierra 上完成的。

解决方案


我们需要将凭证传递给 Docker 守护进程。在基于 Systemd 的 Linux 上,由于 docker daemon 由 systemd 管理,我们需要为 docker daemon 设置 systemd 配置。

对于 mac,我们需要想办法在 Mac 中做类似的事情,并且需要了解 Mac docker daemon 是如何配置和启动的。

显然,Mac docker daemon 无法传递环境变量存在问题,因此会限制选项。发布问题的人最终以docker-cloudwatchlogs

stackoverflow 中提到了 Mac 上的几种方法。

但是,如果这是关于 docker compose,则可能有另一种方法可以使用 Docker Composer 功能通过环境变量传递 AWS 凭证。

或者在运行 docker compose 命令行时简单地设置环境变量。

AWS_ACCESS_KEY_ID=... AWS_SECRET_ACCESS_KEY= ... AWS_SESSION_TOKEN= ... docker-compose up ...

请参阅Docker for Mac 也不能使用从文件加载的环境变量

关于 AWS IAM 权限,请确保 AWS 凭证的 AWS 账户具有Docker 文档中指定的 IAM 权限。
