如何将构图图像推送到ECR？

Question

我有一个docker-compose文件:

version: '3.4'
services:
  nginx:
    container_name: some-nginx
    image: nginx:latest
    restart: always
    ports:
      - 80:80
      - 443:443

  mongodb:
    container_name: some-mongo
    image: mongo:latest
    environment:
      - MONGO_DATA_DIR=/data/db
      - MONGO_LOG_DIR=/dev/null
    ports:
      - 27017:27017
    command: mongod --smallfiles --logpath=/dev/null # --quiet

我想使用命令推送到Amazon Elastic Container Registry(ECR):

docker tag testapper:latest 619625705037.dkr.ecr.us-east-2.amazonaws.com/testapper:latest

但我收到一条消息:

来自守护程序的错误响应:没有这样的图像:testapper:latest

当我跑步时,docker-compose build我收到了这条消息:

nginx uses an image, skipping
mongodb uses an image, skipping

这是什么意思？如何将我的图像推送到ECR？

Answer 1

你的docker容器都使用现有的图像(image关键字)

services:
  nginx:
    image: nginx:latest

  mongodb:
    image: mongo:latest

因此,您不需要构建它们.

我相信ECS会自己找到这些官方图片,因此您无需将它们推送到您的私人仓库(ECR).(不是100%肯定)

如果您确实想要推送自定义构建的图像,一般流程是

docker build -t your_image_name:tag path
docker tag your_image_name:tag 619625705037.dkr.ecr.us-east-2.amazonaws.com/your_image_name:tag
# or
docker build -t 619625705037.dkr.ecr.us-east-2.amazonaws.com/your_image_name:tag path


docker push 619625705037.dkr.ecr.us-east-2.amazonaws.com/your_image_name:tag

docker-compose build如果你的撰写文件是这样的话,你可以同时使用它来构建和标记

services:
  nginx:
    image: 619625705037.dkr.ecr.us-east-2.amazonaws.com/your_image_name:tag
    build: ./my-nginx-path
