How “Docker Stop” Terminates A Container?

When you use a `docker stop` as a docker command, Docker initiates a immediate shutdown process. The container receives the SIGTERM signal, allowing its main process to perform the cleanup tasks, such as saving state or closing connections. If the container doesn’t respond to the SIGTERM signal within a specified timeout (default is 10 seconds), Docker sends a SIGKILL signal, forcefully terminating the container....

Options For Customizing The Docker Stop Command

1. `-t` or `–time`: It sets a custom timeout period for the docker container to respond to the SIGTERM signal before forcefully stopping it. In this example the docker container with my_containername wait for the 30seconds after sending the SIGTERM signal then it will go for forcefully termination if it is not responded in that 30seconds....

How “docker stop” Works?

When you execute a docker stop command along with the container name or id, the docker on behind sends two single signals to the container before the termination. The first signal known as SIGTERM signal warns the container for possible termination after the default grace time of 10seconds it sends another signal known as SIGKILL signal that terminates the running container. The Flow of docker stop explain in steps as follows:...

How “docker kill” Works?

Docker kill command sends only one signal known as SIGKILL signal that terminate the running container, it doesn’t provide any grace time for the container’s main process to clean the tasks, close the connections.
