为 docker-compose 文件设置预挂钩

[英]Setting pre-hook for docker-compose file

原文 2020-02-26 12:42:56 4 1 python/ django/ docker/ docker-compose

I am running a dockerized django app and I am looking for a way to run (a) directive(s) every time before I build a docker container.我正在运行一个 dockerized django 应用程序，我正在寻找一种在构建 docker 容器之前每次运行（a）指令的方法。 More concretely, I would like to run docker-compose -f production.yml run --rm django python manage.py check --deploy each time before I either build or up the production.yml file and stop the build process if any erroroccur.更具体地说，我想在每次构建或启动 production.yml 文件之前docker-compose -f production.yml run --rm django python manage.py check --deploy并在发生任何错误时停止构建过程. Like a pre-hook.就像一个预钩。

I know I could achieve this with a bash-script, yet I was wondering if there is a way of doing this inside the docker-compose file.我知道我可以用 bash 脚本来实现这一点，但我想知道是否有办法在 docker-compose 文件中做到这一点。 I can't find anything in the docker documentation (except events, but I don't understand if they serve for what I want to achieve) about it and I assume that this is not possible.我在 docker 文档中找不到任何关于它的内容（事件除外，但我不明白它们是否为我想要实现的目标服务），我认为这是不可能的。 Yet, maybe it is in fact possible or maybe there is a hacky workaround?然而，也许这实际上是可能的，或者也许有一个hacky的解决方法？

Thanks in advance for any tips.提前感谢您的任何提示。
