Configure Remote Clusters

Elastic Orchestration Elastic Cloud on Kubernetes (ECK)

So, I'm trying to configure the remote cluster connections. But I believe I'm missing something.
I'm following this instructions:

I have 2 different ES clusters on 2 different kubernetes and I would like them to see each other.
Here is where I got confused, I understand I have to duplicate the configuration for both cluster.

Lets call it cluster-one and cluster-two, basically both cluster would have the same configuration

  transport:
    service:
      metadata:
        annotations:
          external-dns.alpha.kubernetes.io/hostname: elasticsearch-transport.my.domain.com
          service.beta.kubernetes.io/aws-load-balancer-type: "nlb"
          service.beta.kubernetes.io/aws-load-balancer-internal: "true"
          service.beta.kubernetes.io/aws-load-balancer-scheme: "internal"
          service.beta.kubernetes.io/aws-load-balancer-proxy-protocol: "*"
          service.beta.kubernetes.io/aws-load-balancer-subnets: "MY_SUBNETS"
      spec:
        type: LoadBalancer
        externalTrafficPolicy: "Local"
    tls:
      certificate:
        secretName: elasticsearch-my-domain
      certificateAuthorities:
        configMapName: remote-certs

I have a couple of questions:

  • I have to share the certificates and expose the transport layer on both cluster?
  • Should I change the DNS name of should I use the same as elasticsearch?
  • This would create a new LB, would it be possible to add the port to the http service and use the same LB?

Thanks
