docker-compose 未显示任何代码更改 [英] docker-compose not showing any changes to code

问题描述

我正在开发一个使用 docker-compose up 启动和运行的项目.我对 docker-compose 不是很熟悉，我在文档中找不到答案.根据文档，up 命令从 docker 文件重建容器，但这似乎没有发生.

I am working on a project that uses docker-compose up to start up and run. I am not very familiar with docker-compose and I couldn't really find an answer in the docs. According to the docs the up command rebuilds the container from the docker file, however this does not seem to happen.

当我尝试添加用于调试的 print 命令时，没有任何反应.该程序已经抛出了一些打印命令，我尝试更改它们以确保它们始终打印相同.我是否必须在 up 命令中添加一些东西来重建容器?

When I try to add print commands for debugging nothing happens. The program already throws a few print commands and I tried changing those to be sure, and they always print the same. Do I have to add something to the up command to make the container rebuild?

docker-compose/yml:

docker-compose/yml:

dockbrato:
  build: .
  volumes:
    - "/sys:/sys"
    - "/var/run/docker.sock:/var/run/docker.sock"

推荐答案

据我所知，docker-compose up 只构建不存在的图像；它不会重建源已更改的映像.如果要重建镜像，请在 docker-compose up 之前运行 docker-compose build.

As far as I can tell, docker-compose up only builds images that don't exist already; it will not rebuild an image whose source has changed. If you want to rebuild your image, run docker-compose build before docker-compose up.
