I have deployed Openstack ocata version using kolla-ansible and would like to use glance backend as s3. I tried putting s3 under glance_store in glance-api.conf and restarted the glance-api container.

[glance_store]
default_store = s3
stores = s3

I get "ERROR glance ConfigFileValueError: Value for option default_store is not valid: Valid values are [file, filesystem, http, https, swift, swift+http, swift+https, swift+config, rbd, sheepdog, cinder, vsphere], but found 's3'"

Some forums say that s3 support is removed from openstack newton release.
But Is there any way to support s3 in my openstack ocata setup?
Any help here would be highly appreciated.
