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, --config KEY

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

-s, --state

Just print the container's state.

-p, --pid

Just print the container's pid.

-i, --ips

Just print the container's IP addresses.

-S, --stats

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, --no-humanize

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

Common Options

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 /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.

Examples

lxc-info -n foo

Show information for foo.

lxc-info -n 'ubuntu.*'

Show information for all containers whose name starts with ubuntu.

lxc-info -n foo -c lxc.net.0.veth.pair

prints the veth pair name of foo.
