Configure back ends
|
|
===================
|
|
|
|
The Image service supports several back ends for storing virtual machine
|
|
images:
|
|
|
|
* Block Storage service (cinder)
|
|
* A directory on a local file system
|
|
* HTTP
|
|
* Ceph RBD
|
|
* Sheepdog
|
|
* Object Storage service (swift)
|
|
* VMware ESX
|
|
|
|
.. note::
|
|
|
|
You must use only ``raw`` image formats with the Ceph RBD back end.
|
|
|
|
The following tables detail the options available for each.

Configure vCenter data stores for the Image service back end
|
|
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
To use vCenter data stores for the Image service back end, you must
|
|
update the ``glance-api.conf`` file, as follows:
|
|
|
|
- Add data store parameters to the ``VMware Datastore Store Options``
|
|
section.
|
|
|
|
- Specify vSphere as the back end.
|
|
|
|
.. note::
|
|
|
|
You must configure any configured Image service data stores for
|
|
the Compute service.
|
|
|
|
You can specify vCenter data stores directly by using the data store
|
|
name or Storage Policy Based Management (SPBM), which requires vCenter
|
|
Server 5.5 or later. For details, see :ref:`glance-backend-vmware-DS`.
|
|
|
|
.. note::
|
|
|
|
If you intend to use multiple data stores for the back end, use the
|
|
SPBM feature.
|
|
|
|
In the ``glance_store`` section, set the ``stores`` and ``default_store``
|
|
options to ``vsphere``, as shown in this code sample:
|
|
|
|
.. code:: ini
|
|
|
|
[glance_store]
|
|
# List of stores enabled. Valid stores are: cinder, file, http, rbd,
|
|
# sheepdog, swift, vsphere (list value)
|
|
stores = file,http,vsphere
|
|
# Which back end scheme should Glance use by default is not specified
|
|
# in a request to add a new image to Glance? Known schemes are determined
|
|
# by the known_stores option below.
|
|
# Default: 'file'
|
|
default_store = vsphere
|
|
|
|
The following table describes the parameters in the
|
|
``VMware Datastore Store Options`` section:
|
|
|
|
.. include:: ../tables/glance-vmware.rst
|
|
|
|
The following block of text shows a sample configuration:
|
|
|
|
.. code:: ini
|
|
|
|
# ============ VMware Datastore Store Options =====================

# ESX/ESXi or vCenter Server target system.

|
|

# Inventory path to a datacenter (string value)
|
|
# Value optional when vmware_server_ip is an ESX/ESXi host: if specified
|
|
# should be `ha-datacenter`.
|
|
vmware_datacenter_path = DATACENTER
|
|
|
|
# Datastore associated with the datacenter (string value)
|
|
vmware_datastore_name = datastore1
|
|
|
|
# PBM service WSDL file location URL. e.g.
|

# file:///opt/SDK/spbm/wsdl/pbmService.wsdl Not setting this

|
# (string value)
|
|
#vmware_pbm_wsdl_location =
|
|
|
|
# The PBM policy. If `pbm_wsdl_location` is set, a PBM policy needs
|

|
|
# in which the images will be stored.
|
|
#vmware_pbm_policy =
|
|
|
|
# The interval used for polling remote tasks
|
|
# invoked on VMware ESX/VC server in seconds (integer value)
|
|
vmware_task_poll_interval = 5

Configure vCenter data stores for the back end
|
|
----------------------------------------------
|
|
|
|
You can specify a vCenter data store for the back end by setting the
|
|
``vmware_datastore_name`` parameter value to the vCenter name of
|
|
the data store. This configuration limits the back end to a single
|
|
data store.
|
|
|
|
If present, comment or delete the ``vmware_pbm_wsdl_location`` and
|
|
``vmware_pbm_policy`` parameters.
|
|
|
|
Uncomment and define the ``vmware_datastore_name`` parameter with the
|
|
name of the vCenter data store.
|
|
|
|
Complete the other vCenter configuration parameters as appropriate.
