-
Verify that the Docker daemon is running:
ps aux | grep dockerdNote the Docker PID.
-
Check system load:
topExit using
q. -
Stop the dockerd process:
sudo -i kill -SIGSTOP <dockerd_PID> -
Check the load to see if there is a change:
topNotice it indicates there is one stopped process. Exit using
q. -
Restart the Docker daemon:
sudo kill -i -SIGCONT <dockerd_PID>
-
-
Challenge
Check the Current Process Priority of the dockerd Process and if It Is Not 10, Set It to 10
-
Get the current priority (niceness):
ps axo ni,pid,comm | grep dockerd -
Set the Docker niceness to +10:
sudo -i renice -n 10 <dockerd_PID> -
Verify the change:
ps axo ni,pid,comm | grep dockerd
