Hi,
I am trying to integrate OpenStack Juno Keystone with the Ceph Object
Gateway(radosw).
I want to use keystone as the users authority. A user that keystone
authorizes to access
the gateway will also be created on the radosgw. Tokens that keystone
validates will be
considered as valid by the rados gateway.
I have deployed a 4 node ceph cluster running on Ubuntu 14.04
Host1: ppm-c240-admin.xyz.com (10.x.x.123)
Host2: ppm-c240-ceph1.xyz.com (10.x.x.124)
Host3: ppm-c240-ceph2.xyz.com (10.x.x.125)
Host4: ppm-c240-ceph3.xyz.com (10.x.x.126)
My ceph -w output is as follows,
ceph@ppm-c240-admin:~/my-cluster$ ceph -w
cluster df18a088-2a70-43f9-b07f-ce8cf7c3349c

The host ppm-c240-ceph3.xyz.com (10.x.x.126) is running the Ceph Object
Gateway(Radosgw)
I can see the radosgw up and running,

I am following the steps in the URL:
http://ceph.com/docs/master/radosgw/keystone/ for the radosgw integration
with keystone.
The /etc/ceph/ceph.conf snippet on all the 4 ceph nodes are as follows,
rgw keystone url = 10.x.x.175:35357
rgw keystone admin token = xyz123
rgw keystone accepted roles = Member, admin
rgw keystone token cache size = 10000
rgw keystone revocation interval = 15 * 60
rgw s3 auth use keystone = true
nss db path = /var/lib/nssdb
Where 10.x.x.175 is the I.P. Address of the Keystone server (Single Node
Juno install on Ubuntu 14.04)
Keystone itself is pointing to the Ceph Object Gateway as an object-storage
endpoint:
ppmuser@ppm-dc-c3sv3-ju:~$ keystone service-create --name swift --type
object-store --description "Object Storage"
ppmuser@ppm-dc-c3sv3-ju:~$ keystone endpoint-create --service-id
a70fbbc539434fa5bf8c0977e36161a4 --publicurl
http://ppm-c240-ceph3.xyz.com/swift/v1 --internalurl
http://ppm-c240-ceph3.xyz.com/swift/v1 --adminurl
http://ppm-c240-ceph3.xyz.com/swift/v1
I have the following queries
1) I am following the steps in
http://docs.openstack.org/juno/install-guide/install/apt/content/swift
install-controller-node.html. Do I need to create a swift user in keystone
on my OpenStack node ?
2) Once the swift user is created, do I have to do a $ keystone
user-role-add --user swift --tenant service --role admin ?
3) I did not find any documents on how to proceed further and test the
integrated setup, so any pointers would be most welcome.
ps: I am cross posting this to the openstack and ceph lists because it
involves an integration of both.
Regards,
