lxc-execute(1)                                                                     lxc-execute(1)

       lxc-execute - run an application inside a container.

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

       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  de‐
       fined, the default isolation is used.

       This  command is mainly used when you want to quickly launch an application in an isolated

       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.  (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.

       -f, --rcfile config_file
              Specify the configuration file to configure the virtualization and isolation  func‐
              tionalities for the container.

              This configuration file if present will be used even if there is already a configu‐
              ration 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 processing. Any arguments af‐
              ter the -- are treated as arguments to command.

              This option is useful when you want specify options to command and don't want  lxc-
              execute to interpret them.

       These options are common to most of lxc commands.

       -?, -h, --help
              Print a longer usage message than normal.

              Give the usage message

       -q, --quiet
              mute on

       -P, --lxcpath=PATH
              Use an alternate container path. The default is /var/lib/lxc.

       -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 :

              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

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