How to push to a compose-built image to ECR manually?

I have a docker-compose file:

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

I want to push to Amazon Elastic Container Registry (ECR), using the commands:

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

But I got an message:

Error response from daemon: No such image: testapper:latest

When I run docker-compose build I got this message:

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

What does this mean? How do push my images to ECR?

Your docker containers are all using existing images (image keyword)

services:
  nginx:
    image: nginx:latest

  mongodb:
    image: mongo:latest

therefore you do not need to build them.

I believe ECS will find these official images by itself, so you do not need to push them to your private repo (ECR). (not 100% sure)

In case you do want to push a custom built image, the general flow is 

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

You can use docker-compose build to build and tag at the same time if your compose file is like

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