Docker撰写时间过长

Question

在Visual Studio 2019的一个解决方案中，我在Docker的微服务架构中有很多项目。现在我有一个docker-compose.yml文件。建立一个图像似乎花费太长时间，而花费太长时间则意味着一个多小时。

services:
  nosql.data:
    image: mongo

  mongo1:
    image: mongo
    hostname: mongo1
    container_name: mongo1
    command: "--replSet rs0"

  mongo2:
    image: mongo
    hostname: mongo2
    container_name: mongo2
    command: "--replSet rs0"

  mongo3:
    image: mongo
    hostname: mongo3
    container_name: mongo3
    command: "--replSet rs0"

  mysql.data: 
    image: mysql:latest
    container_name: mysql.data

  rabbit:
    image: rabbitmq:management
    container_name: rabbit

  es01:
    image: docker.elastic.co/elasticsearch/elasticsearch:7.2.0
    container_name: es01
    ulimits:
      memlock:
        soft: -1
        hard: -1
    volumes:
      - esdata01:/elasticsearch/data

  es02:
    image: docker.elastic.co/elasticsearch/elasticsearch:7.2.0
    container_name: es02
    ulimits:
      memlock:
        soft: -1
        hard: -1
    volumes:
      - esdata02:/elasticsearch/data

  cnx.useraccessmanagement.api:
    image: ${REGISTRY:}/useraccessmanagement.api:${PLATFORM:-linux}-${TAG:-latest}
    build:
      context: .
      dockerfile: src/Services/Program2/Dockerfile 
    depends_on:
       - nosql.data
       - mysql.data
       - rabbit

  cnx.identity.api:
    image: ${REGISTRY:}/identity.api:${PLATFORM:-linux}-${TAG:-latest}
    build:
      context: .
      dockerfile: src/Services/Program1/Dockerfile

  cnx.apigateway:
    image: ${REGISTRY:}/apigateway:${PLATFORM:-linux}-${TAG:-latest}
    build:
      context: .
      dockerfile: src/ApiGateway/Dockerfile
    depends_on:
      - identity.api
      - nosql.data
      - mysql.data
      - rabbit 

volumes:
  esdata01:
    driver: local
  esdata02:
    driver: local

项目文件大小几乎为1gb，就此docker compose文件中设置的构建上下文而言，影响构建时间是否重要？如果可以，该如何优化呢？
