At first

It describes how to make detailed settings with the docker compose up command that has recently become available.

Please refer to this article for the basics. [Introduction to Docker x ECS] Deploy ECS with docker compose up

Setting method

It is ok if you draw it in the docker-compose file. It's mostly as shown on the reference page (the details seem to be different).

version: "3"
services:
  front:
    image: [AWS_ID].dkr.ecr.ap-northeast-1.amazonaws.com/front:latest
    #--- AWS settings ---
    deploy:
      x-aws-autoscaling:
        min: 2
        max: 10
      resources:
        reservations:
          memory: 300Mb
    #--- AWS settings ---
    command: bash -c "yarn run build && yarn start"
    ports:
      - "3000:3000"
    depends_on:
      - back
  back:
    image: [AWS_ID].dkr.ecr.ap-northeast-1.amazonaws.com/back:latest
    command: rails s -p 3001 -b 0.0.0.0
    ports:
      - "3001:3001"

By the way, if you want to specify vpc, you can do as follows. By doing this, RDS, elasticache, etc. can be created in advance.

version: "3"
x-aws-vpc: [VPC_ID]
services:
  front: #Abbreviation
  back: #Abbreviation
