Docker Compose 始终强制构建一项服务

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

如何强制只service_in_development从头开始构建图像，以便我在其中获取最新的代码？

我已经研究了文件参考cache_from中的选项docker-compose，但找不到任何关于它到底做什么的明确解释。

澄清：

在这个问题中，我询问了一个选项，可以使用以下选项强制重建特定服务：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，我现在也会对此感到满意。

另外，我正在谈论强制“重建”图像。不仅仅是服务的“娱乐”。

Answer 1

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

文档中更多有用的参数
