Kill docker exec command will not terminate the spawned process #9098
Description
Whenever a process is launched via docker exec, it seems that killing docker exec will not terminate the process. For example:
> docker run -d --name test-exec busybox top
> docker exec -it test-exec sh
/ # # we have an exec shell now. assume pid of docker exec is 1234
> kill 1234
# docker exec process is terminated atm, but `nsenter-exec` process is still running with sh as its child
I would expect that killing docker exec -it process will also kill the spawned process, or there should be a way to stop the spawn process similar to how docker stop works.
