lxc-info: query information about a container

NAME

lxc-info - query information about a container

SYNOPSIS

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

DESCRIPTION

lxc-info queries and shows information about a container.

OPTIONS

[-c KEY]

Print a configuration key from the container. This option may be given multiple times to print out multiple key = value pairs.

[-s]

Just print the container's state.

[-p]

Just print the container's pid.

[-i]

Just print the container's IP addresses.

[-S]

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).

[-H]

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