NAME
lxc-execute - run an application inside a container.
SYNOPSIS
lxc-execute {-n name} [-d] [-f config_file] [-s KEY=VAL] [-u, --uid uid] [-g, --gid gid]
[-- command]
DESCRIPTION
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.
OPTIONS
-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.
-d, --daemon
Run the container as a daemon. As the container has no more tty, if an error occurs
nothing will be displayed, the log file can be used to check the error.
-u, --uid uid
Executes the command with user ID (use numerical value) uid inside the container.
--g, --gid gid
Executes the command with group ID (use numerical value) gid inside the container.
-- 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.
