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, --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

- -P, --lxcpath=PATH
- Use an alternate container path. The default is /var/lib/lxc.

- -l, --logpriority=LEVEL
- Set log priority to LEVEL. The default log priority is ERROR.
Possible values are : FATAL, ALERT, CRIT, WARN, ERROR, NOTICE, INFO,
DEBUG, TRACE.
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.*'
