django - 在ElasticBeanstalk上部署多容器应用程序时出现CannotPullContainerError

Question

我有一个要在ElasticBeanstalk上部署的多容器应用程序。以下是我的文件。

Dockerfile

FROM python:2.7

WORKDIR /app

ADD . /app

RUN apt-get update && \
    apt-get upgrade -y && \
    apt-get install -y \
    apt-utils \

    rm -rf /var/lib/apt/lists/*

RUN pip install -r requirements.txt

EXPOSE 8000

RUN chmod +x entry_point.sh

docker-compose.yml

version: "2"
services:
  db:
    restart: always
    container_name: docker_test-db
    image: postgres:9.6
    expose:

    mem_limit: 10m
    environment:
      - POSTGRES_NAME=postgres
      - POSTGRES_USER=postgres
      - POSTGRES_PASSWORD=postgres
      - POSTGRES_DB=docker_test

  redis:

      - redis

    command: celery -A docker_test worker -l info
    links:
      - db
      - redis
    mem_limit: 10m
    depends_on:
      - web

  cbeat:
    image: docker_test
    container_name: docker_test-cbeat
    command: celery beat --loglevel=info
    links:
      - db
      - redis
    mem_limit: 10m
    depends_on:
      - web

在本地系统上运行文件时，我会工作。但是，当我将其上传到elasticbeanstalk时，出现了以下错误。

ECS task stopped due to: Essential container in task exited. (celery: db: cbeat: web: CannotPullContainerError: API error (404): pull access denied for docker_test, repository does not exist or may require 'docker login' redis: )

我通过使用container-transform将docker-compose.yml转换为Dockerrun.aws.json。对于上面的文件，下面是我的Dockerrun.aws.json。

我该如何解决这个问题？

请将镜像“docker_test”推送到dockerhub或ECR，以便Beanstalk从中提取镜像。目前，它在您的本地上，而ECS代理对此一无所知。

标记并推送docker_test图像到dockerhub＆ECR等注册表。

用Dockerrun.aws.json更新图像存储库URL。

允许Beanstalk提取图像。
