lxc-info: query information about a container


lxc-info - query information about a container


lxc-info {-n name} [-c KEY] [-s] [-p] [-i] [-S] [-H]


lxc-info queries and shows information about a container.


[-c KEY]
Print a configuration key from the container. This option may be given multiple times to print out multiple key = value pairs.
Just print the container's state.
Just print the container's pid.
Just print the container's IP addresses.
Just print the container's statistics. Note that for performance reasons the kernel does not account kernel memory use unless a kernel memory limit is set. If a limit is not set, lxc-info will display kernel memory use as 0. A limit can be set by specifying

            lxc.cgroup.memory.kmem.limit_in_bytes = number

in your container configuration file, see lxc.conf(5).

Print the container's statistics in raw, non-humanized form. The default is to print statistics in humanized form.


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.

Show the version number.
