• Related issues: #4678 [BUG] Unable to successfully create LoadBalancer service from Guest cluster post 1.2.1 upgrade

Category:

• Rancher

Verification Steps

1. Prepare three nodes Harvester and import with Rancher

2. Provision a RKE2 guest cluster in Rancher

3. Ensure the installed Harvester cloud provider version is 0.2.3 or above

4. Create the first pool, specify the etcd and control plane roles

5. Create the second pool, specify the work role only

6. Create a nginx deployment using Harvester storage class

7. Create a load balancer service with dhcp type and bind to nginx deployment

8. Check can install the load balancer

9. Create a standalone load balancer service, set the following annotation

10. Access to the guest cluster VM, check the load balancer service can get EXTERNAL_IP

11. Prepare three nodes Harvester and import with Rancher

12. Provision a RKE2 guest cluster in Rancher

13. Create the first pool, specify the control plane role only

14. Create the second pool, specify the etcd role only

15. Create the third pool, specify the worker role only

16. Repeat the steps 13 - 17 to create load balancer service

17. Prepare three nodes Harvester and import with Rancher

18. Provision a RKE2 guest cluster in Rancher

19. Create the only one pool, specify the control plane, etcd and workers roles

Expected Results

• Control-plane, ETCD and worker in same pool:

  • Can successfully create LoadBalancer service on RKE2 guest cluster
  • All load balance type service have assigned the EXTERNAL_IP

• Control-plane and ETCD in A pool, worker in B pool:

  • Can successfully create LoadBalancer service on RKE2 guest cluster
  • All load balance type service have assigned the EXTERNAL_IP

• Control-plane in A pool, ETCD in B pool and worker in C pool:

  • Can successfully create LoadBalancer service on RKE2 guest cluster
  • All load balance type service have assigned the EXTERNAL_IP
