Docker Compose找不到本地软件包 [英] Docker compose can't find local package

问题描述

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：

So I created REST api and one grpc service in GOlang and now I want to compose it in docker compose. My docker-compose looks like this:

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之后，我收到错误消息，说里面的本地软件包

After I run docker-compose up I get error that local packages that are inside of go-rest and item-service could not be found.

ajdinahmetovic_rest_1 exited with code 1

$ b退出
$ b

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。如我所见，问题出在我开发应用程序的道路上。

However when I move docker compose file to go-rest folder, rest app succcessfuly runs but my item service fails. As i see problem is in my path to go apps.

推荐答案

几个小时后，我终于意识到问题出在哪里。
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项目的文件夹处于同一级别

After couple of hours I finally realized what the problem was. My volume path for item-service and go-rest were wrong. Becuse my docker-compose file is on the same level with folders of projects item-service and go-rest

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

，我的音量路径为

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，因此需要将其更改为

They were not able to acces my project folder so they need to be changed to

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