Difference between "docker stop" and "docker kill"

 To stop a running container, you can use either "docker stop" or "docker kill" command to do so. Although it seems doing the same thing, actually there is a slight difference between them.

"docker stop" command will send a hardware signal SIGTERM to the container, if the process received the SIGTERM signal, the developer can code to do some clean up and releasing some resources before terminating the process.

However "docker kill" command will send a hardware signal SIGKILL to the container and stop it immediately.

Usually "docker stop" is used to stop a running container. If the container is hanging there for a long time or failed to stop. Then you can try to use "docker kill"to kill the container anyway.
