Direct run command:

docker run -it --privileged --pid=host justincormack/nsenter1

After pulling, the image will be entered

Step 2: position the container

Run in the command line of the container corresponding to this image:

cd /var/lib/docker/containers

This is all the containers. The file name is the corresponding ID

cd The Container ID you want to change/

Here you can modify the container file, and the modified results will be applied to the docker container.
