SSL configuration for ingress in aws EKS

I have two domains and both of these domains have separate SSL certificates. Is it possible to set up ssl for these domains using a single ingress configuration?

Cluster: EKS

Ingress controller: AWS ALB ingress controller

Solution

  • Add in annotations comma-separated string of your certs.

    alb.ingress.kubernetes.io/certificate-arn: arn:aws:acm:us-west-2:xxxxx:certificate/cert1,arn:aws:acm:us-west-2:xxxxx:certificate/cert2,arn:aws:acm:us-west-2:xxxxx:certificate/cert3

    https://github.com/kubernetes-sigs/aws-load-balancer-controller/blob/main/docs/guide/ingress/annotations.md#certificate-arn

    Also, you can assign a certificate via AWS web console: EC2 -> load balancers -> listeners -> tls:443 -> view/edit certificates and add there an additional cert from ACM
