LXC-AUTOSTART(1)LXC-AUTOSTART(1)NAMElxc-autostart - start/stop/kill auto-started containers
SYNOPSISlxc-autostart [ -k ] [ -L ] [ -r ] [ -s ] [ -a ] [ -g groups ] [
-t timeout ]
DESCRIPTIONlxc-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 con‐
tainers without a lxc.group set will be affected. [-t TIMEOUT] speci‐
fies 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 spec‐
ified 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 speci‐
fied 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 containers with lxc.start.auto == 1 that is a mem‐
ber 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 overload‐
ing 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.
