Stop a docker container:
The docker engine provides a stop option which can be used to stop the execution of a container which is in running state.
The syntax is as follows:
# docker stop <CONTAINER-NAME | CONTAINER-NAME ID
[email protected]:~$ sudo docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES

Now we use the stop option to stop the running container.
[email protected]:~$ sudo docker stop do_nothing_container
do_nothing_container
The other arguments stop option accepts in –time or -t which stops the container in specified amount of time in seconds.
[email protected]:~$ sudo docker -v stop -t 20 do_nothing_container
do_nothing_container
[email protected]:~$ sudo docker ps -a | grep do_nothing

Once the command is typed the cli goes into non-interactive mode till the times expires and finally returns back after the container is successfully stopped; The container is killed and moved to the stopped state.
