由于我的项目结构，我面临着大型 docker 构建上下文的问题。在我的根目录中，我有用于公共(public)代码的 lib 文件夹和微服务文件夹。现在我想为 miscroservice1 构建只包含 lib 文件夹并忽略其他微服务。

我在根文件夹中运行 docker build 命令，因为在微服务文件夹中运行命令会在构建上下文之外给出错误 Forbidden path

rootFolder
-- lib
-- microservice1/Dockerfile
-- microservice2/Dockerfile
-- microservice3/Dockerfile

最佳答案

您可以创建.dockerignore在您的根目录中并添加

microservice1/
microservice2/
microservice3/

version: "3"
services:
  microservice1:
    build:
      context: .
      dockerfile: ./microservice1/Dockerfile
    volumes:
      - "./path/to/share:/path/to/mount/on/container"
    ports:
      - "<host>:<container>"
    links:
      - rootservice # defines a dns record in /etc/hosts to point to rootservice
  microservice2:
    build:
      context: .
      dockerfile: ./microservice2/Dockerfile
    volumes:
      - "./path/to/share:/path/to/mount/on/container"
    ports:
      - "<host>:<container>"
    links:
      - rootservice # defines a dns record in /etc/hosts to point to rootservice
      - microservice1
  rootservice:
    build:
      context: .
      dockerfile: ./Dockerfile
    volumes:
      - "./path/to/share:/path/to/mount/on/container"
    ports:
      - "<host>:<container>"
    depends_on:
      - microservice1
      - microservice2
    ports:
      - "<host1>:<container1>"
      - "<host2>:<container2>"
