Can NSX ALB (AKO) Reassign a VIP IP Address Without a Change in Kubernetes?

[MehdiF]

Can NSX ALB more specifically AKO independently change the IP address of a virual service VIP (a Kubernetes LoadBalancer service), or does it only modify the IP in response to a change triggered by Kubernetes, either automatically or through a manual (human) action?

[Bogdan_Ionut]

Short answer: AKO does not independently change the VIP of a Kubernetes LoadBalancer Service. Any VIP change you see is always driven by Kubernetes state or a human/operator action, not by AKO acting on its own.

Hello Bogdan, 

Thanks for your reply

That's what I kept telling my colleagues, but they were and still are convinced that the problem is NSX...

 

Changes were made to external DNS and DNS to fix the IP change issue.

 

Since then, the problem has disappeared :)
