      Figured out the problem. I am seeing the problem with openstack + Contrail setup. From the file robot/library/eteutils/OpenstackLibrary.py function get_openstack_service_url we are trying to fetch the public endpoint and filter tenant_id. Also I don't see any value coming as tenant_id to this function


      def get_openstack_service_url(self, alias, servicetype, region = None, tenant_id = None):
      """Get Openstack service catalog from the current alias"""
      response = self._cache.switch(alias)
      if isinstance(response, basestring):
      jsonResponse = json.loads(response);
      else:
      jsonResponse = response;
      endPoint = None;
      #print "Kranthi: jsonResponse is %s" % jsonResponse
      for catalogEntry in jsonResponse['access']['serviceCatalog']:
      if self.__determine_match(catalogEntry['type'], servicetype):
      listOfEndpoints = catalogEntry['endpoints'];
      print "Kranthi: listOfEndpoints %s" % listOfEndpoints
      # filter out non matching regions if provided
      listOfEndpoints[:] = [x for x in listOfEndpoints if self.__determine_match(x['region'], region)];
      # filter out non matching tenants if provided
      listOfEndpoints[:] = [y for y in listOfEndpoints if self.__determine_match(y['tenantId'], tenant_id)];
      if len(listOfEndpoints) > 0:
      endPoint = listOfEndpoints[0]['publicURL'];
      if endPoint == None:
      self.builtin.should_not_be_empty("", "Service Endpoint Url should not be empty")
      return endPoint;


      Not sure why we are trying to match tenant_id from endpoint list and tenant_id in argument. Perhaps we can retrieve the tenant_id information from endpoint URL like below

      Kranthi: listOfEndpoints [{u'adminURL': u'http://192.168.105.11:8004/v1/c15a42323a454987a15e634d704efe32', u'region': u'RegionOne', u'publicURL': u'http://192.168.105.11:8004/v1/c15a42323a454987a15e634d704efe32', u'id': u'0fb5ecb2dcfd4e1aa6b4ed4fd54b6ac6', u'internalURL': u'http://192.168.105.11:8004/v1/c15a42323a454987a15e634d704efe32'}]

      where c15a42323a454987a15e634d704efe32 is tenant-id because we pass tenantName

      As a workaround add a condition if tenat_id is present then only validate tenant_id from endpoint list. However this also doesn't make any sense by fetching tenant_id directly from endpoint as an attribute


      def get_openstack_service_url(self, alias, servicetype, region = None, tenant_id = None):
      """Get Openstack service catalog from the current alias"""
      response = self._cache.switch(alias)
      if isinstance(response, basestring):
      jsonResponse = json.loads(response);
      else:
      jsonResponse = response;
      endPoint = None;
      #print "Kranthi: jsonResponse is %s" % jsonResponse
      for catalogEntry in jsonResponse['access']['serviceCatalog']:
      if self.__determine_match(catalogEntry['type'], servicetype):
      listOfEndpoints = catalogEntry['endpoints'];
      print "Kranthi: listOfEndpoints %s" % listOfEndpoints
      # filter out non matching regions if provided
      listOfEndpoints[:] = [x for x in listOfEndpoints if self.__determine_match(x['region'], region)];
      # filter out non matching tenants if provided
      if tenant_id:
      listOfEndpoints[:] = [y for y in listOfEndpoints if self.__determine_match(y['tenantId'], tenant_id)];
      if len(listOfEndpoints) > 0:
      endPoint = listOfEndpoints[0]['publicURL'];
      if endPoint == None:
      self.builtin.should_not_be_empty("", "Service Endpoint Url should not be empty")
      return endPoint;
