在通过 Kops 在 AWS 中创建的 kubernetes 中创建 nlb-ip 负载均衡器

Question

I have a Kubernetes cluster created through the Kops tool. And I have a requirement to expose my service using a network load balancer. And the target groups should be based on IP based. I have found the answer using the annotation mentioned in the site https://kubernetes-sigs.github.io/aws-load-balancer-controller/v2.1/guide/service/nlb_ip_mode/ .

This seems to work only when we have the cluster created through EKS. Since I'm using a kops tool could you please help me in installing alb load balancer controller which is one of the requirements to create a nlb-IP loadbalancers?

Answer 1

If you want to use IP targets, not instance targets, you need to use a CNI that provisions VPC IPs per pod. Those are:

• Cilium with ipam
• Lyft VPC
• AWS VPC

Then you need to install AWS LB controller , which supports this mode both for NLB and ALB. I would wait until kOps 1.20, which will support installing this controller out of the box, including the various permissions that needs setting.
