NAME

       lxc-start - run an application inside a container.

SYNOPSIS

       lxc-start {-n name} [-f config_file] [-c console_device] [-L console_logfile] [-d] [-F]
                 [-p pid_file] [-s KEY=VAL] [-C] [--share-[net|ipc|uts] name|pid] [command]

DESCRIPTION

       lxc-start 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.

       If no command is specified, lxc-start will use the command defined in lxc.init.cmd  or  if
       not set, the default "/sbin/init" command to run a system container.

OPTIONS

       -d, --daemon
              Run the container as a daemon. As the container has no more tty, if an error occurs
              nothing will be displayed, the log file can be used to check the  error.  (This  is
              the default mode)

       -F, --foreground
              Run  the  container  in the foreground. In this mode, the container console will be
              attached to the current tty and signals will be routed directly to the container.

       -p, --pidfile pid_file
              Create a file with the process id.

       -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).

       -c, --console console_device
              Specify a device to use for the container's console, for example /dev/tty8. If this
              option is not specified the current terminal will be used unless -d is specified.

       -L, --console-log console_logfile
              Specify a file to log the container's console output to.

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

       -C, --close-all-fds
              If any file descriptors are inherited, close them. If this option is not specified,
              then  lxc-start will exit with failure instead. Note: --daemon implies --close-all-
              fds.

       --share-net name|pid
              Inherit a network namespace from a name container or a pid. The  network  namespace
              will continue to be managed by the original owner. The network configuration of the
              starting container is ignored and the up/down scripts won't be executed.

       --share-ipc name|pid
              Inherit an IPC namespace from a name container or a pid.

       --share-uts name|pid
              Inherit a UTS namespace from a name container or a pid. The starting LXC  will  not
              set the hostname, but the container OS may do it anyway.

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

       -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 :
              FATAL, ALERT, CRIT, WARN, ERROR, NOTICE, INFO, DEBUG, TRACE.

              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.

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.
