Ceph Object Gateway support
|
|
===========================
|
|
|
|
Overview
|
|
========
|
|
Ceph project is a powerful distributed storage system. It contains object store
|
|
and provides a RADOS Gateway Swift API which is compatible with OpenStack Swift
|
|
API. These two APIs use different formats for their temporary URLs.
|
|
|
|
Ironic added support for RADOS Gateway temporary URL in the Mitaka release.
|
|
|
|
Configure Ironic and Glance with RADOS Gateway
|
|
==============================================
|
|
|
|
#. Install Ceph storage with RADOS Gateway. See `Ceph documentation <http://docs.ceph.com/docs>`_.
|
|
|
|
#. Create RADOS Gateway credentials for Glance by executing the following
|
|
commands on the RADOS Gateway admin host::
|
|
|
|
sudo radosgw-admin user create --uid="GLANCE_USERNAME" --display-name="User for Glance"
|
|
|
|
sudo radosgw-admin subuser create --uid=GLANCE_USERNAME --subuser=GLANCE_USERNAME:swift --access=full
|
|
|
|
sudo radosgw-admin key create --subuser=GLANCE_USERNAME:swift --key-type=swift --secret=STORE_KEY
|
|
|
|
sudo radosgw-admin user modify --uid=GLANCE_USERNAME --temp-url-key=TEMP_URL_KEY
|
|
|
|
Replace GLANCE_USERNAME with a user name for Glance access, and replace
|
|
STORE_KEY and TEMP_URL_KEY with suitable keys.
|
|
|
|
Note: Do not use "--gen-secret" CLI parameter because it will cause the
|
|
"radosgw-admin" utility to generate keys with slash symbols which do not
|
|
work with Glance.
|
|
|
|
#. Configure Glance API service for RADOS Swift API as backend. Edit the
|
|
configuration file for the Glance API service (is typically located at
|
|
``/etc/glance/glance-api.conf``). Replace RADOS_IP and PORT with the IP/port
|
|
of the RADOS Gateway API service::
|
|
|
|
[glance_store]
|
|
|
|
stores = file, http, swift
|
|
default_store = swift
|
|
swift_store_auth_version = 1
|
|
swift_store_auth_address = http://RADOS_IP:PORT/auth/1.0
|
|
swift_store_user = GLANCE_USERNAME:swift
|
|
swift_store_key = STORE_KEY
|
|
swift_store_container = glance
|
|
swift_store_create_container_on_put = True
|
|
|
|
Note: RADOS Gateway uses FastCGI protocol for interacting with HTTP server.
|
|
Read your HTTP server documentation if you want to enable HTTPS support.
|
|
|
|
#. Restart Glance API service and upload all needed images.
|
|
|
|
#. Change Ironic configuration file on the conductor host(s) as follows::
|
|
|
|
[glance]
|
|
|
|
swift_container = glance
|
|
swift_api_version = v1
|
|
swift_endpoint_url = http://RADOS_IP:PORT
|
|
swift_temp_url_key = TEMP_URL_KEY
|
|
|
|
[deploy]
|
|
|
|
object_store_endpoint_type = radosgw
|
|
|
|
#. Restart Ironic conductor service(s).
