Description Omer Schwartz 2021-06-14 09:08:53 UTC

+++ This bug was initially created as a clone of Bug #1887424 +++

Description of problem:

HEAT stack does not support the load balancing algorithm SOURCE_IP_PORT in pool definitions

Version-Release number of selected component (if applicable):

OSP: 16.1
HEAT: all versions


How reproducible:
 100%

Steps to Reproduce:
1.Build a yaml HEAT template with the parameter "lb_algorithm: SOURCE_IP_PORT"
2.Try to run the template with "openstack stack create -t ..."

Actual results:

"RESP BODY: {"code": 400, "title": "Bad Request", "explanation": "The server could not comply with the request since it is either malformed or otherwise incorrect.", "error": {"type": "StackValidationFailed", "traceback": null, "message": "Property error: : resources.pool.properties.lb_algorithm: : \"SOURCE_IP_PORT\" is not an allowed value [\"ROUND_ROBIN\", \"LEAST_CONNECTIONS\", \"SOURCE_IP\"]"}}


Expected results:

The stack should be successfully built


Additional info:


SOURCE_IP_PORT is the ONLY load balancing algorithm currently supported by the OVN Provider driver.

Comment 5 David Rosenfeld 2021-09-15 17:36:48 UTC

Enabled octavia by including: -e /usr/share/openstack-tripleo-heat-templates/environments/services/octavia.yaml in deploy command

Created a load balancer, listener, and pool:

openstack loadbalancer create --name lb1 --vip-subnet-id lb-subnet
openstack loadbalancer listener create --name listener1 --protocol HTTP --protocol-port 80 lb1
openstack loadbalancer pool create --name pool1 --lb-algorithm ROUND_ROBIN --listener listener1 --protocol HTTP

Used this yaml:

heat_template_version: rocky

parameters:


resources:
   TestLbPool:
        type: OS::Octavia::Pool
        properties:
          admin_state_up: false
          description: "Test Pool"
          lb_algorithm: "SOURCE_IP_PORT"
          listener: "c057dc8f-f81b-4ea4-8e07-3cb652cad6f8"
          protocol: "HTTP"

Was able to create a stack using SOURCE_IP_PORT load balancing algorithm:

openstack stack create -t testlb.yaml stacktest
