config_tempest.py breaks if Rados Gateway is configured for object-store

Solution Verified - Updated

Environment

  • Red Hat Enterprise Linux 7.x
  • Red Hat Ceph Storage 1.3.x
  • Red Hat Ceph Storage 2.x
  • Red Hat OpenStack Platform
  • OpenStack Tempest test suite version 10.0.0-3

Issue

  • If the Rados Gateway is configured as object-store instead of swift the tools/config_tempest.py script will fail.

Fails with exception: 

CRITICAL tempest [-] ServiceError: Request on service 'object-store' with url 'http://192.0.0.0:8087/info' failed with code 404
TRACE tempest Traceback (most recent call last):

TRACE tempest ServiceError: Request on service 'object-store' with url 'http://192.0.0.0:8087/info' failed with code 404

Resolution

  • During the Tempest configuration, set the following parameters in the Ceph configuration file (ceph.conf) on the RGW node (instance-name being the name of the RGW node) and restart the RGW:
[client.radosgw.instance-name]
rgw_swift_url_prefix = "/"
rgw_enable_apis=swift, swift_auth, admin
  • Once the configuration is complete, comment the parameters out and restart the RGW:
[client.radosgw.instance-name]
#rgw_swift_url_prefix = "/"
#rgw_enable_apis=swift, swift_auth, admin

Root Cause

  • If the Rados Gateway is configured as object-store instead of swift the tools/config_tempest.py script will fail because RadowGW does not implement the /info api call.
