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

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

DESCRIPTION
       lxc-autostart  processes containers with lxc.start.auto set. It lets the user start, shut‐
       down, kill, restart containers in the right order, waiting the right time.  Supports  fil‐
       tering by lxc.group or just run against all defined containers. It can also be used by ex‐
       ternal tools in list mode where no action will be performed and the list of affected  con‐
       tainers (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 con‐
              tainer 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 pro‐
              cessed.  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.

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 con‐
       tainers  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.
