LXC-EXECUTE(1)                                                LXC-EXECUTE(1)

NAME         top

       lxc-execute - run an application inside a container.

SYNOPSIS         top

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

DESCRIPTION         top

       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
       application 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.  (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.

OPTIONS         top

       -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
              processing. Any arguments after 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.

COMMON OPTIONS         top

       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
              /usr/local/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 : 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.

       --rcfile=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).

       --version
              Show the version number.
