Question

所以我在GOlang中创建了REST api和一个grpc服务，现在我想在docker compose中进行编写。我的docker-compose看起来像这样：

version: '3'
services: 
  db:
    image: postgres
    environment:
      POSTGRES_DB: db_1
      POSTGRES_USER: postgres
      POSTGRES_PASSWORD: tajna
      PGDATA: /tmp
    volumes:
      - ./db/sql/user/1_create.sql:/docker-entrypoint-initdb.d/1-create_user.sql
      - ./db/sql/item/2_create.sql:/docker-entrypoint-initdb.d/2-create_item.sql
    ports:
      - 5432:5432
    networks: 
      apinetwork:
  service:
    build: ./item-service
    command: ["go", "run", "."]
    volumes:
      - .:/go/src/github.com/ajdinahmetovic/item-service
    ports:
      - "4040:4040"
    depends_on: 
      - db
    links:
      - db
    networks: 
      apinetwork:
  rest:
    image: go-rest
    build: 
      context: ./go-rest
      dockerfile: Dockerfile
    command: ["go", "run", "main.go"]
    volumes:
      - .:/go/src/github.com/ajdinahmetovic/go-rest
    ports:
      - "3000:3000"
    depends_on:
      - service
    networks: 
      apinetwork:
networks:
  apinetwork:
    driver: bridge

在我运行docker-compose up之后，出现错误，提示找不到go-rest和item-service内部的本地软件包。

rest_1     |    /go/src/github.com/ajdinahmetovic/go-rest/httputil (from $GOPATH)
ajdinahmetovic_rest_1 exited with code 1

但是，当我将docker compose文件移动到go-rest文件夹时，rest app成功运行，但是我的项目服务失败。我认为问题出在我开发应用程序的道路上。

几个小时后，我终于意识到了问题所在。我用于项目服务和休息的音量路径错误。因为我的docker-compose文件与项目item-service和go-rest项目的文件夹位于同一级别

-go-rest
 -Project files
-item-service
 -Project files
-docker-compose.yaml

我的音量路径是

volumes:
      - .:/go/src/github.com/ajdinahmetovic/go-rest
volumes:
      - .:/go/src/github.com/ajdinahmetovic/item-service

他们无法访问我的项目文件夹，因此需要将它们更改为

volumes:
      - .:/go-rest
volumes:
      - .:/item-service

Docker compose找不到本地软件包
