Dockerrunscriptinhostondocker-composeup

thank you for watching this question.

So my question relates to best practices on how to run a script on a docker-compose up directive.

Currently i'm sharing a volume between host and container to allow for the script changes to be visible to both host and container. Similar to a watching script polling for changes on configuration file.

The script has to act on host on changes according to predefined rules.

So my question is:

How could I start this script on a docker-compose up directive or even from the dockerfile of the service, so that whenever the container goes up the "watcher" can find any changes being made and writing to.

The container in question will always run over a debian / ubuntu OS and should be architecture independent, meaning it should be able to run on ARM as well.

Thanks in advance

I would like to know as well, why was the question downvoted just because some people don't understand it.

I wish to run a script on the Host, not inside the container.. I need the Host to change its network interface configurations to easily adapt any environment The HOST needs to change I repeat.. This should be seamless to the user, and easily editable on a Web interface running Inside a CONTAINER to adapt to new environments.

我目前使用基于crontab的主机上运行的脚本来执行此操作。我只想了解最佳实践和示例，了解如何从容器内部在HOST上运行脚本，以便安装操作员可以像部署docker-compose一样轻松进行部署。

谢谢
