我正在使用 docker compose 创建两个容器，一个用于 dynamodb local，一个用于 Nodejs Express 应用程序。

docker-compose.dev.yml

version: '3'

services:
  dynamodb-local:
    command: "-jar DynamoDBLocal.jar -sharedDb -optimizeDbBeforeStartup -dbPath ./data"
    image: "amazon/dynamodb-local:latest"
    container_name: dynamodb-local
    ports:
      - "8000:8000"
    volumes:
      - "./docker/dynamodb:/home/dynamodblocal/data"
    working_dir: /home/dynamodblocal
    networks:
      - dynamodb-network

  node-app:
    depends_on:
        - dynamodb-local
    container_name: dev-nodejs-backend
    ports:
      - '3000:3000'
    volumes:
      - .:/usr/src/node-app
    environment:
      AWS_ACCESS_KEY_ID: 'DUMMYIDEXAMPLE'
      AWS_SECRET_ACCESS_KEY: 'DUMMYEXAMPLEKEY'
    networks:
      - dynamodb-network
    command: yarn dev -L

networks:
  dynamodb-network:
    driver: bridge

Dockerfile
