IpAddress condition of an RGW bucket policy doesn't work for access via ha-proxy

This document (000019874) is provided subject to the disclaimer at the end of this document.

Environment

SUSE Enterprise Storage 6
SUSE Enterprise Storage 7

Situation

An IpAddress access condition of an RGW bucket policy, for example configured as

"Condition" : {
  "IpAddress" : {
    "aws:SourceIp": [ "
192.0.2.0/24" ]
  }
}


does not match for access via an HTTP load balancing proxy.

Resolution

As the RGW receives the request from the proxy, aws:SourceIp by default is that of the proxy. If all requests are handled by the proxy (i.e., no direct requests to RGW), adding
  rgw remote addr param = HTTP_X_FORWARDED_FOR
to the [client.rgw.INSTANCE] section in ceph.conf, followed by a restart of the RGW, changes the semantics of aws:SourceIp to contain the value of the specified HTTP header, in this case HTTP_X_FORWARDED_FOR.

As an alternative, access control can also be implemented by proxy configuration.
