Hi, I have a k8s cluster with 3 nodes and a load balancer with an ingress IP address. I want to give my customers an IP address they can use to verify requests from my server.
However, I realized that the IPs set in the X-Forwared-For header are the IPs of the Nodes (VMs). Is it possible to have an IP that isn’t associated with the nodes because if I add another node to my node pool, or a completely new node pool, I’d need to give my customers the IPs of those new nodes again.

One viable solution could be utilizing a Load Balancer.
The Load Balancer’s static IP address can be the unifying point between your customers and multiple backend nodes. As you scale your infrastructure by adding more nodes, the load balancer efficiently routes traffic to these nodes without changing the IP your customers interact with.
However, it’s key to note that the X-Forwarded-For header will still send the originating IP address of a client connecting to the server. To change this, you might need to consider implementing custom configurations, possibly tweaking your application or ingress controller to accomplish this.
Hope that this helps!
Hi there,
Quick update here, DigitalOcean have just released a managed component for maintaining host routes in DOKS:
https://www.digitalocean.com/blog/introducing-doks-routing-agent
The new DOKS routing agent is a managed component for configuring static routes on Kubernetes worker nodes. It is a direct response to user feedback on its predecessor, the static route operator, and introduces new features to enhance routing flexibility. Despite being a managed component, the DOKS routing agent is included at no additional cost for users.
