NAME
lxc-create - creates a container
SYNOPSIS
lxc-create {-n name} [-f config_file] {-t template} [-B backingstore]
[-- template-options]
DESCRIPTION
lxc-create creates a system object where is stored the configuration
information and where can be stored user information. The identifier
name is used to specify the container to be used with the different lxc
commands.
The object is a directory created in /var/lib/lxc and identified by its
name.
The object is the definition of the different resources an application
can use or can see. The more the configuration file contains
information, the more the container is isolated and the more the
application is jailed.
If the configuration file config_file is not specified, the container
will be created with the default isolation: processes, sysv ipc and
mount points.
OPTIONS
-f, --config config_file
Specify the configuration file to configure the virtualization
and isolation functionalities for the container.
-t, --template template
'template' is the short name of an existing 'lxc-template'
script that is called by lxc-create, eg. busybox, debian,
fedora, ubuntu or sshd. Refer to the examples in
/usr/share/lxc/templates for details of the expected script
structure. Alternatively, the full path to an executable
template script can also be passed as a parameter. "none" can
be used to force lxc-create to skip rootfs creation.
-B, --bdev backingstore
'backingstore' is one of 'dir', 'lvm', 'loop', 'btrfs', 'zfs',
'rbd', or 'best'. The default is 'dir', meaning that the
container root filesystem will be a directory under
/var/lib/lxc/container/rootfs. This backing store type allows
the optional --dir ROOTFS to be specified, meaning that the
container rootfs should be placed under the specified path,
rather than the default. (The 'none' backingstore type is an
alias for 'dir'.) If 'btrfs' is specified, then the target
filesystem must be btrfs, and the container rootfs will be
created as a new subvolume. This allows snapshotted clones to be
created, but also causes rsync --one-filesystem to treat it as a
separate filesystem. If backingstore is 'lvm', then an lvm
block device will be used and the following further options are
available: --lvname lvname1 will create an LV named lvname1
rather than the default, which is the container name. --vgname
vgname1 will create the LV in volume group vgname1 rather than
the default, lxc. --thinpool thinpool1 will create the LV as a
thin-provisioned volume in the pool named thinpool1 rather than
the default, lxc. --fstype FSTYPE will create an FSTYPE
filesystem on the LV, rather than the default, which is ext4.
--fssize SIZE will create a LV (and filesystem) of size SIZE
rather than the default, which is 1G.
If backingstore is 'loop', you can use --fstype FSTYPE and
--fssize SIZE as 'lvm'. The default values for these options are
the same as 'lvm'.
If backingstore is 'rbd', then you will need to have a valid
configuration in ceph.conf and a ceph.client.admin.keyring
defined. You can specify the following options : --rbdname
RBDNAME will create a blockdevice named RBDNAME rather than the
default, which is the container name. --rbdpool POOL will
create the blockdevice in the pool named POOL, rather than the
default, which is 'lxc'.
If backingstore is 'best', then lxc will try, in order, btrfs,
zfs, lvm, and finally a directory backing store.
-- template-options
This will pass template-options to the template as arguments. To
see the list of options supported by the template, you can run
lxc-create -t TEMPLATE -h.
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.
--version
Show the version number.
DIAGNOSTIC
The container already exists
As the message mention it, you try to create a container but
there is a container with the same name. You can use the lxc-ls
command to list the available containers on the system.
