machinectl — Control the systemd machine manager
machinectl
[OPTIONS...] {COMMAND} [NAME...]
machinectl may be used to introspect and control the state of the systemd(1) virtual machine and container registration manager systemd-machined.service(8).
The following options are understood:
-h
, --help
¶Prints a short help text and exits.
--version
¶Prints a short version string and exits.
-p
, --property=
¶When showing
machine properties, limit the
output to certain properties as
specified by the argument. If not
specified, all set properties are
shown. The argument should be a
property name, such as
"Name
". If
specified more than once, all
properties with the specified names
are shown.
-a
, --all
¶When showing machine properties, show all properties regardless of whether they are set or not.
-l
, --full
¶Do not ellipsize process tree entries.
--no-pager
¶Do not pipe output into a pager.
--no-ask-password
¶Do not query the user for authentication for privileged operations.
--kill-who=
¶When used with
kill-machine,
choose which processes to kill. Must
be one of leader
, or
all
to select whether
to kill only the leader process of the
machine or all processes of the
machine. If omitted, defaults to
all
.
-s
, --signal=
¶When used with
kill-machine, choose
which signal to send to selected
processes. Must be one of the
well-known signal specifiers, such as
SIGTERM
,
SIGINT
or
SIGSTOP
. If
omitted, defaults to
SIGTERM
.
-H
, --host
¶Execute operation
remotely. Specify a hostname, or
username and hostname separated by "@
",
to connect to. This will use SSH to
talk to the remote machine manager
instance.
-P
, --privileged
¶Acquire privileges via PolicyKit before executing the operation.
The following commands are understood:
List currently running virtual machines and containers.
Show terse runtime status information about one or more virtual machines and containers. This function is intended to generate human-readable output. If you are looking for computer-parsable output, use show instead.
Show properties of one
or more registered virtual machines or
containers or the manager itself. If
no argument is specified, properties
of the manager will be shown. If an
ID is specified, properties of this
virtual machine or container are
shown. By default, empty properties
are suppressed. Use
--all
to show those
too. To select specific properties to
show, use
--property=
. This
command is intended to be used
whenever computer-parsable output is
required. Use
status if you are
looking for formatted human-readable
output.
Terminates a virtual machine or container. This kills all processes of the virtual machine or container and deallocates all resources attached to that instance.
Send a signal to one
or more processes of the virtual
machine or container. This means
processes as seen by the host, not the
processes inside the virtual machine
or container.
Use --kill-who=
to
select which process to kill. Use
--signal=
to select
the signal to send.
