LXC-EXECUTE(1) LXC-EXECUTE(1)
lxc-execute - run an application inside a container.
lxc-execute -n name [ -f config_file ] [ -s KEY=VAL ] [ -- command
]
lxc-execute runs the specified command inside the container specified
by name.
It will setup the container according to the configuration previously
defined with the lxc-create command or with the configuration file
parameter. If no configuration is defined, the default isolation is
used.
This command is mainly used when you want to quickly launch an
application in an isolated environment.
lxc-execute command will run the specified command into the container
via an intermediate process, lxc-init. This lxc-init after launching
the specified command, will wait for its end and all other reparented
processes. (to support daemons in the container). In other words,
in the container, lxc-init has the pid 1 and the first process of the
application has the pid 2.
The above lxc-init is designed to forward received signals to the
started command.
-f, --rcfile config_file
Specify the configuration file to configure the virtualization
and isolation functionalities for the container.
This configuration file if present will be used even if there
is already a configuration file present in the previously
created container (via lxc-create).
-s, --define KEY=VAL
Assign value VAL to configuration variable KEY. This overrides
any assignment done in config_file.
-- Signal the end of options and disables further option
processing. Any arguments after the -- are treated as
arguments to command.
This option is useful when you want specify options to command
and don't want lxc-execute to interpret them.
These options are common to most of lxc commands.
-?, -h, --help
Print a longer usage message than normal.
--usage
Give the usage message
-q, --quiet
mute on
-P, --lxcpath=PATH
Use an alternate container path. The default is
/usr/local/var/lib/lxc.
-o, --logfile=FILE
Output to an alternate log FILE. The default is no log.
-l, --logpriority=LEVEL
Set log priority to LEVEL. The default log priority is ERROR.
Possible values are : FATAL, CRIT, WARN, ERROR, NOTICE, INFO,
DEBUG.
Note that this option is setting the priority of the events
log in the alternate log file. It do not have effect on the
ERROR events log on stderr.
-n, --name=NAME
Use container identifier NAME. The container identifier
format is an alphanumeric string.
--rcfile=FILE
Specify the configuration file to configure the virtualization
and isolation functionalities for the container.
This configuration file if present will be used even if there
is already a configuration file present in the previously
created container (via lxc-create).
--version
Show the version number.
The container is busy
The specified container is already running an application. You
should stop it before reuse this container or create a new
one.
