docker - Docker Compose 总是强制构建一个服务

Question

这是我的 docker-compose 文件的一部分：

version: "3.2"
services:
  cachable_service:
    image: my/cachable_service:x.x
    build:
      context: .
      dockerfile: cachable_service_Dockerfile

  service_in_development:
    image: my/service_in_development:latest
    build:
      context: .
      dockerfile: Dockerfile
    depends_on:
      - cachable_service

如何仅强制service_in_development始终从头开始构建图像，以便在那里获取最新代码？

我已经查看cache_from了文件参考中的选项docker-compose，但我找不到任何关于它到底做什么的明确解释。

说明：

在这个问题中，我问的是使用docker-compose.yml文件本身中的选项强制仅重建特定服务的选项。但是，如果命令行选项让我这样做，我现在也会很高兴。

另外，我说的是强制“重建”图像。不仅仅是服务的“娱乐”。

您可以使用以下命令重建所有图像：

docker-compose up --build --force-recreate

强制重建一项服务：

docker-compose up --build --force-recreate service-name-here

文档中更有用的参数
