Ceph RADOS-GW object storage plugin issue

[rohityadavcloud]

Following review and testing of the feature, some missing features and issues can be addressed in the next phase: #8389 (comment)

The following are applicable only for the Ceph RGW object-storage plugin:

• Bucket creation fails when any of the options are specified or these options aren't supported: quota, versioning & encryption, bucket policy
• During Bucket creation, locking feature/option is ignored
• User quota not enforced/configured
• Bucket policy fails and throws exception:

• UI browser doesn't work (due to cors issue, couldn't figure out how to configure radosgw for that)

ISSUE TYPE

• Improvement Request

@wido @rohityadavcloud , given that #8389 is merged, can this be closed? (and marked with milestone 4.20.0)

Correct. Closing this one.

i got CORS issue 403 error via ACS browser UI, is it currently a limitation?

[wido]

My CORS knowledge is limited, but I think this needs to be addressed on the RGW site where you make sure it sends out the proper CORS headers. Without them your browser will block your access.

I’ve been looking into this, and it seems like Ceph RGW and CORS configurations are actually based on bucket policies. Unless ACS sets a default bucket policy when creating a bucket, otherwise the browser UI will not work. I’m thinking about other options, like using an intermediate proxy. In the meantime, I’d like to see if we can disable the browser UI as an option in the management configuration. That way, users won’t be confused. What do you think?

I managed to workaround it with haproxy, here is the configuration which will allow ACS object storage browser UI operate with Ceph RGW.
