NAME

       lxc-autostart - start/stop/kill auto-started containers

SYNOPSIS

       lxc-autostart [-k] [-L] [-r] [-s] [-a] [-A] [-g groups] [-t timeout]

DESCRIPTION

       lxc-autostart processes containers with lxc.start.auto set. It lets the
       user start, shutdown, kill, restart  containers  in  the  right  order,
       waiting  the  right  time.  Supports filtering by lxc.group or just run
       against all defined containers. It can also be used by  external  tools
       in list mode where no action will be performed and the list of affected
       containers (and if relevant, delays) will be shown.

       The [-r], [-s] and [-k] options specify the action to perform.  If none
       is  specified,  then the containers will be started.  [-a] and [-g] are
       used to specify which containers will  be  affected.  By  default  only
       containers  without  a  lxc.group  set  will be affected.  [-t TIMEOUT]
       specifies the maximum amount of time  to  wait  for  the  container  to
       complete the shutdown or reboot.

OPTIONS

       -r,--reboot
              Request a reboot of the container.

       -s,--shutdown
              Request  a  clean  shutdown. If a [-t timeout] greater than 0 is
              given and the container has not shut down within this period, it
              will be killed as with the [-k kill] option.

       -k,--kill
              Rather  than  requesting  a  clean  shutdown  of  the container,
              explicitly kill all tasks in the container.

       -L,--list
              Rather than performing the  action,  just  print  the  container
              name.

       -t,--timeout TIMEOUT
              Wait TIMEOUT seconds before hard-stopping the container.

       -g,--group GROUP
              Comma  separated  list  of  groups  to select (defaults to those
              without a lxc.group - the  NULL  group).   This  option  may  be
              specified  multiple  times  and  the arguments concatenated. The
              NULL or empty  group  may  be  specified  as  a  leading  comma,
              trailing  comma,  embedded double comma, or empty argument where
              the NULL group should be processed.  Groups are processed in the
              order specified on the command line. Multiple invocations of the
              -g option may be freely  intermixed  with  the  comma  separated
              lists and will be combined in specified order.

       -a,--all
              Ignore lxc.group and select all auto-started containers.

       -A,--ignore-auto
              Ignore  the  lxc.start.auto  flag. Combined with -a, will select
              all containers on the system.

AUTOSTART AND SYSTEM BOOT

       The lxc-autostart command is used as part of the  LXC  system  service,
       when enabled to run on host system at bootup and at shutdown. It's used
       to select which containers to start in what order and how much to delay
       between each startup when the host system boots.

       Each  container can be part of any number of groups or no group at all.
       Two groups are special. One is the NULL group, i.e. the container  does
       not belong to any group. The other group is the "onboot" group.

       When  the  system  boots  with  the  LXC service enabled, it will first
       attempt to boot any containers with  lxc.start.auto  ==  1  that  is  a
       member  of  the  "onboot"  group.  The  startup  will  be  in  order of
       lxc.start.order.  If an lxc.start.delay has been specified, that  delay
       will  be  honored before attempting to start the next container to give
       the  current  container  time  to  begin  initialization   and   reduce
       overloading the host system. After starting the members of the "onboot"
       group,  the  LXC  system  will  proceed   to   boot   containers   with
       lxc.start.auto == 1 which are not members of any group (the NULL group)
       and proceed as with the onboot group.

STARTUP GROUP EXAMPLES

       -g "onboot,"
              Start the "onboot" group first then the NULL group.

              This is the equivalent of: -g onboot -g "".

       -g "dns,web,,onboot"
              Starts the "dns" group first, the "web" group second,  then  the
              NULL group followed by the "onboot" group.

              This  is  the  equivalent of: -g dns,web -g ,onboot or -g dns -g
              web -g "" -g onboot.
