Docker executes a command in a container outside the container

Sometimes we want to execute a command in a container but don't want to enter the container. What to do then?

So the script can be written like this

#!/bin/bash
DOCKER_ID=62f3f40ab240
sudo docker exec -it $DOCKER_ID /bin/bash -c 'cd /packages/detectron && python tools/train.py'

done

Supplementary knowledge: Solve the problem of seamlessly calling shell commands between Docker containers and host machines

I won't say any more nonsense, let's see the solution~

nsenter -t 1 -m -u -n -i sh -c "echo hello world!"

(Add privilege permissions to the docker container and set pid: "host")

The above article about how to execute a command in a container outside the container is all I have to share with you. I hope it can give you a reference. I also hope that you will support 123WORDPRESS.COM.
