Set limit on Ceph rgw user usage

Question

I want to limit each user on rgw object gateway (radosgw) usage that gets from radosgw-admin usage show --uid=johndoe --start-date=2012-03-01 --end-date=2012-04-01 Any way that I can set limit on these parameters from usage show command? For example user johndoe can only have 1000ops per month or 1000000bytes put_object per month.

It's okay if there is a solution in nginx or in other layers of the Ceph object gateway stack.

Answer 1

ceph doesn't have any tools for limit request to rgw. you should use reverse proxy module of nginx for two reason : 1- Use caching layer in front of rgw for improve performance 2- Implement limitation in receiving requests to rgw.

Answer 2

You can now use quotas on buckets and users to limit their usage. You can also set default quotas in your ceph config file /etc/ceph/ceph.conf for when new users are created the quotas will be automatically applied. ceph rgw quotas
