создает контейнер (creates a container)
Имя (Name)
lxc-create - creates a container
Синопсис (Synopsis)
lxc-create -n name [ -f config_file ] -t template [ -B
backingstore ] [ -- template-options ]
Описание (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 /usr/local/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.
Параметры (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/local/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 /usr/local/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.
Общие параметры (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
/usr/local/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, 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.
Диагностика (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.
