Docker composing不适用于多个项目

我的文件夹结构如下所示：

[Services] | +--[IdentityService] (this folder contains Docker & docker-compose file) | +--[ProductService] (this folder contains Docker & docker-compose file) | +--[ApiGateway] (this folder contains Docker & docker-compose file) | +--docker-compose.yml

version: "3"
services:
  api_gateway:
    image: cog/mfp_api_gateway
    build:
      context: .
      dockerfile: Services/ApiGateway/ApiGateway/Dockerfile
    ports:
      - "8082:9000"
    depends_on:
      - identity_service
      - product_service

  identity_service:
    image: cog/mfp_identity_service
    build:
      context: .
      dockerfile: Services/IdentityService/Dockerfile
    ports:
      - "8080:9001"
    depends_on:
      - db

  product_service:
    image: cog/mfp_product_service
    build:
      context: .
      dockerfile: Services/ProductService/Dockerfile
    ports:
      - "8081:9002"
    depends_on:
      - db

  db:
    image: "mcr.microsoft.com/mssql/server:2017-latest"
    environment:
        SA_PASSWORD: "MYPASSWORD"
        ACCEPT_EULA: "Y"
    ports:
      - "1433:1433"
    volumes:
      - ./.db:/var/opt/mssql/
      - /var/opt/mssql/data

我的docker compose.yml如下所示：

---

在这里，当我单独运行docker文件时，所有文件都正常生成和运行。但是，当我可以运行outerdocker compose.yml时，我得到了与路径相关的错误。我需要在docker compose.yml文件中指定相对路径吗？

docker命令在docker文件中（更具体地说是

COPY

）是相对于当前docker上下文的

当您单独构建映像时，我猜您从每个

服务

目录运行

docker build

，这意味着上下文就是该特定目录

当您通过docker compose构建它们时，您明确地说上下文是

，这意味着

docker compose.yml

所在的目录

---

只要更改生成的上下文，您就会得到预期的结果=>

context:./Services/

。您可以在使用默认名称时删除

dockerfile

声明。

为什么同时指定生成和映像？它可能不知道要使用哪个。是的，docker-compose.yml路径是相对的（除非以斜杠开头），但看起来您已经将它们正确地写为relativeal，因此应该停止将上下文指定为”。“@Shardj你的意思是，分别构建它们，并在yaml中使用这些映像，而不是使用build命令？我只使用docker compose build，我不会指定映像，因为你只会混淆docker compose，因为它不知道是查找生成的映像还是指定的映像。@Shardj请帮助我重写外部yaml文件。”
