停止Docker容器时是否可以运行命令？

Question

I'm using docker-compose to organize containers for a JS application.
The source container sports command: npm start , pretty standard, to spin up the live application. However, that timeouts when I ask it to stop.

I was wondering if it's possible to have docker-compose stop to run a command inside the container - that could properly terminate the application.

Answer 1

docker-compose stop just sends a SIGTERM to your container and if it does not stop after 10secs (configurable) SIGKILL follows. So if you want to customize this behavior, you should handle signal inside your entrypoint (if you have one).
