How to use Ceph as a OpenStack Glance backend

Setup Ceph Client Authentication

• Create Glance keyrings

  ceph auth get-or-create client.glance mon 'profile rbd' osd 'profile rbd pool=images' mgr 'profile rbd pool=images' > /etc/ceph/ceph.client.glance.keyring
  

• Duplicate ceph.conf to ceph-glance.conf with impicit keyring

  [global]
    ...
    keyring = /etc/ceph/ceph.client.glance.keyring

Edit /etc/glance/glance-api.conf

• Add rdb storage to enabled_backends in [DEFAULT] section. You can pick any name instead of ceph

  enabled_backends = ceph:rbd
  

• Set default_backend to ceph in [glance_store] section

  default_backend = ceph
  

• Create new ceph section

  [ceph]
  store_description = "Ceph"
  rbd_store_chunk_size = 8
  rbd_store_pool = images
  rbd_store_user = glance
  rbd_store_ceph_conf = /etc/ceph/ceph-glance.conf
  

Restart Glance

sudo glance-control api restart
