LKE LoadBalancer or Ingress for an internal network only?

I need two LKE clusters. One of them for production and second for development environment. The second cluster must be only for an internal network ( If I use LoadBalancer or Ingress, it is implemented by Nodebalancers and has an external IP always. So how to set up LoadBalancer or Ingress for an internal network only?

Hey @mikleand! So, the short answer is yes, you can. However, you will need to employ a workaround at this time. By the end of the year, private VLANs will be available and will make this process a bit simpler. For now, you can follow the below steps.

  • Deploy an Ingress controllerand set its service type to NodePort
  • Manually deploy a Linode running HAProxy or Nginx
  • Make the backends for all Nodes in the cluster point to the NodePort of the Ingress controller
  • Create a Calico network policy to restrict inbound traffic on the Ingress controller to the LoadBalancer

Hope this helps and feel free to followup with any questions!
