2. What is the difference between docker stop and docker kill?
Docker stop / kill commands are used to stop the running docker container.
After docker stop <name>,
“docker ps -a ” will show the status as Exited (0)
But after docker kill <name>,
“docker ps -a ” will show the status as Exited (137).
ie, docker stop sends SIGTERM as process end signal and SIGKILL is send by docker kill.
