lxc-execute - run an application inside a container.
lxc-execute
{-n name} [-d] [-f config_file] [-s KEY=VAL] [-u, --uid
uid] [-g, --gid gid] [-- 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.
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).
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.
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.
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).
