Environment

VMware Integrated OpenStack 6.x

Cause

This happens when the ingress pods needed to access the web ui are pointing to the controllers rather than the VIO Manager where it should run

Resolution

Workaround:

Workaround is to add the nodeSelector Config in the ingress controller.

1. Run the below command to add the nodeSelector parameter on the ingress controller

#kubectl edit deploy vio-ingress-cntl-nginx-ingress-controller

dnsPolicy: ClusterFirstWithHostNet
nodeName: <FQDN of Manager>   <<
nodeSelector:           
  vio-node: ova         <<
restartPolicy: Always

2. Run the below command to add the nodeSelector parameter on the ingress backend 

#kubectl edit deploy vio-ingress-cntl-nginx-ingress-default-backend

dnsPolicy: ClusterFirstWithHostNet
nodeName:  <FQDN of Manager>  <<
nodeSelector:          
  vio-node: ova        <<
restartPolicy: Always

3. Verify correct nodeName reflecting on the ingress pod by running the below command along with the nodeSelector  parameter

#kubectl get pod <ingress_pod_name> -o yaml
