NAME
       lxc-execute - run an application inside a container.

SYNOPSIS
       lxc-execute -n name [ -f config_file ] [ -s KEY=VAL ] [ -- command ]

DESCRIPTION
       lxc-execute  runs  the specified command inside the container specified
       by name.

       It will setup the container according to the  configuration  previously
       defined	with  the  lxc-create  command	or with the configuration file
       parameter.  If no configuration is defined, the	default	 isolation  is
       used.

       This command is mainly used when you want to quickly launch an applica‐
       tion in an isolated environment.

       lxc-execute command will run the specified command into	the  container
       via  an	intermediate process, lxc-init.	 This lxc-init after launching
       the specified command, will wait for its end and all  other  reparented
       processes.   (that  allows  to  support	daemons in the container).  In
       other words, in the container, lxc-init has the pid  1  and  the	 first
       process of the application has the pid 2.

       The  above  lxc-init  is	 designed  to  forward received signals to the
       started command.	 So lxc-kill (1) sent signal is received by  the  user
       specified command (pid 2 in the container).

OPTIONS
	  -f, --rcfile config_file
	      Specify  the  configuration file to configure the virtualization
	      and isolation functionalities for the container.

	      This configuration file if present will be used even if there is
	      already  a  configuration file present in the previously created
	      container (via lxc-create).

	  -s, --define KEY=VAL
	      Assign value VAL to configuration variable KEY.  This  overrides
	      any assignment done in config_file.

       --     Signal  the  end of options and disables further option process‐
	      ing. Any arguments after the -- are treated as arguments.

	      This option is useful when you want to execute, with the command
	      lxc-execute, a command line with its own options.

COMMON OPTIONS
       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.

DIAGNOSTIC
       The container is busy
	      The specified container is already running an  application.  You
	      should stop it before reuse this container or create a new one.
