    Command:

    lxc-execute

    
    
    

    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.
    
                  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.
