What is the diff between docker pause and docker unpause?
The command “docker pause” suspends all processes in the specified containers. Usually the SIGSTOP signal is sent to the process, which is observable by the process being suspended.
EG :
docker pause 9b1247ebff59
docker ps -a
9b1247ebff59 jenkins/jenkins “/sbin/tini — /usr/…” 20 minutes ago Up 17 seconds (Paused) 8080/tcp, 50000/tcp Demo1
EG :
The command “docker unpause” automatically un-suspends the processes in the specified containers. Usually this is accomplished via the SIGCONT signal.
docker unpause 9b1247ebff59
docker ps -a
9b1247ebff59 jenkins/jenkins “/sbin/tini — /usr/…” 20 minutes ago Up 32 seconds 8080/tcp, 50000/tcp Demo1
What is the diff between docker stop and docker kill?
The command “docker stop” sends a SIGTERM signal to the main process inside the specified container and after a grace period will send a SIGKILL signal to the main process. The SIGTERM signal being sent first allows for a graceful cleanup of the process.
EG :
docker stop 9b1247ebff59
docker ps -a
9b1247ebff59 jenkins/jenkins “/sbin/tini — /usr/…” 32 minutes ago Exited (143) 5 seconds ago Demo1
The command “docker kill” sends a SIGKILL signal to the main process inside the specified container. This will automatically kill the main process without no timeout period.
EG :
docker kill 9b1247ebff59
docker ps -a 9b1247ebff59 jenkin
