AKS: How to get rid of load balancer?

When you create an Azure Kubernetes Service (AKS) it creates by default a load balancer and a networking set to access it. It creates it in a separate resource group.

We are however not interested at all in this load balancer, as we are going to use our own load balancer/Ingress configured within Kubernetes itself.

Question: How can we avoid this Load balancer from Azure to be generated all the time when we generate the cluster?

Was discussed in AKS Creation Without Public Load Balancer github issue with afterward explanation

It is possible the SLB IP is just for egress.

Let me try to clarify.

AKS with Basic Load Balancer

You can create it by passing the load balancer sku parameter Has implicit Egress (you won't see a public IP, although it is there on the Azure infrastructure) You can create private services accessible only through private IPs using the internal annotation. https://learn.microsoft.com/en-us/azure/aks/internal-lb AKS with Standard Load Balancer

Used by default on latest clientes, or explicitly by using the same parameter as above Has only explicit egress, which means if there isn't an egress IP the cluster won't have egress and will be broken. This is like the gateway to the internet IP. You can control, pre-create or change this IP (or have more than one) You can create private services accessible through private IPs using the internal annotation. https://learn.microsoft.com/en-us/azure/aks/internal-lb In some cases, enterprises might have egress defined via UDRs through a firewall etc. In which case that egress IP will not be used, and will be effectively not needed. But as of now it will be needed at create time as we don't know the egress path defined. We are no working on a UDR outbound type for SLB that will allow users to confirm they have egress through UDRs and in this case the SLB won't be created with a Public IP for egress

Like @Sajeetharan asked- what is the use case? Also how is it mandatory for you to use AKS? Maybe the same you can easier resolve just regular with kubeadm cluster?
