lxc-kill send the SIGNUM signal to the first process of the container.
The SIGNUM is a numeric value, the signal name is not supported.
If this command is used on an application container ran by lxc-execute, the lxc-init will receive the signal and will forward it to the process 2 which is the command specified in the command line. See lxc-execute (1). Obviously the SIGKILL and SIGSTOP signals are not able to be forwarded, (as per the signal(7) man page).
These options are common to most of lxc commands.
-?, -h, --help
Print a longer usage message than normal.
--usage
Give the usage message
-q, --quiet
mute on
-o, --logfile=FILE
Output to an alternate log FILE. The default is no log.
-l, --logpriority=LEVEL
Set log priority to LEVEL. The default log priority is ERROR. Possible values are : FATAL, CRIT, WARN, ERROR, NOTICE, INFO, DEBUG.
Note that this option is setting the priority of the events log in the alternate log file. It do not have effect on the ERROR events log on stderr.
-n, --name=NAME
Use container identifier NAME. The container identifier format is an alphanumeric string.
To send the signal 26 to the process pi1 running in container 123 :
lxc-execute -n 123 -- pi1 -d 500000 lxc-kill --name=123 26
