Description

When we deploy a F5 CIS controller in nodeport mode in Tanzu k8s cluster, we are able to deploy the k8s native L4 loadbalancer service. However, when we try to deploy a F5 crd "VirtualServer" to use the L7 applications, its unable to create the VIP object in the Big IP controller. K8s shows the Virtualserver CRD is created and IPAM assigns an IP address to the VS, however the object is not getting created in the BIG-IP partition.

Steps To Reproduce

1) Deploy F5 CIS controller in nodeport mode 2) deploy F5 IPAM controller 3) Deploy a F5 virtualserver object

Expected Result

Actual Result

Diagnostic Information

F5 CIS controller pod logs shows virtual server config is missing the serviceport, however we confirm that it exits but still we see the error. please find the below service,VS config and the error in pod logs:

Observations (if any)

When we deploy F5 CIS controller in nodeportlocal mode, and create teh virtualserver object with the same configuration, it works fine. However, nodeportlocal mode does not support k8s native L4 LoadBalancer.

L4 is supported with nodeport only. so we wanted to deploy cis in nodeport mode and create both L4 and L7 services.
