AWS EKS aws-load-balancer-controller

Question

i am trying to install my ca certificates with in ingress controller. I am following this guide. https://docs.aws.amazon.com/eks/latest/userguide/aws-load-balancer-controller.html

I could run cert-manager in Node group while running other pods in fargate. I want to know

I am getting the error that says x509 error certificate is valid for *.corp not aws-load-balancer-webhook-service.kube-system.svc

Do i need to install cert manager though i have my own tls certs. how to route traffic with tls certs from aws-load-balancer-controller.

Thanks, Surya.

Answer 1

You dont need cert manager to use certs with load balancers. Cert manager is a utility to dynamically generate & manage the lifecycle of the certificate.

If you have your own certificate you can import those into your alb or nlb created by load balancer controller for ingress or service objects respectively.
