What is difference between Docker kill and Docker stop commands

In this article, we will see the difference between Docker kill and Docker stop commands.

1. docker stop: Stop a running container (send SIGTERM, and then SIGKILL after grace period) […] The main process inside the container will receive SIGTERM, and after a grace period, SIGKILL.

2. docker kill: Kill a running container (send SIGKILL, or specified signal) […] The main process inside the container will be sent SIGKILL, or any signal specified with option –signal.

So stop attempts to trigger a graceful shutdown by sending the standard POSIX signal SIGTERM, whereas killjust kills the process by default (but also allows to send any other signal):
