lxc-autostart(1) lxc-autostart(1)
lxc-autostart - start/stop/kill auto-started containers
lxc-autostart [-k] [-L] [-r] [-s] [-a] [-A] [-g groups] [-t
timeout]
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 af‐
fected. [-t TIMEOUT] specifies the maximum amount of time to
wait for the container to complete the shutdown or reboot.
-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 contain‐
er name and wait delays until starting the next container.
-t,--timeout TIMEOUT
Wait TIMEOUT seconds before hard-stopping the container.
-g,--groups 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 concate‐
nated. The NULL or empty group may be specified as a lead‐
ing 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 inter‐
mixed 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 se‐
lect all containers on the system.
The lxc-autostart command is used as part of the LXC system ser‐
vice, when enabled to run on host system at bootup and at shut‐
down. 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 con‐
tainer to give the current container time to begin initialization
and reduce overloading the host system. After starting the mem‐
bers 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.
-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.
