Okay... next quick question. When I see something like this:
Copy code
function getLoadBalancer(args, opts) {
    return pulumi.runtime.invoke("aws:elasticloadbalancing/getLoadBalancer:getLoadBalancer", {
        "tags": args.tags,
    }, opts);
How do I find the code for
? For quick context, this is what I'm trying to do. Since I'm launching a service of type LoadBalancer on EKS, I then want to get the ELB object and create a Route53 Alias to it. Since I need ELB name to
, but EKS gives me the DNS Name or Hostname, I wanted to write a new function to get LoadBalancer by that name. I presume this'll also help when I get to launching an Ingress Controller. Of course in your blog post this works great because when you launch a CloudFront distribution, you get a rich object back. Also tell me if I'm going about this all wrong. I have a hello world launching from EKS. Just need to wire up the last Route53 record.

Curious - where are you seeing that code above? That
will call into the AWS Pulumi provider which builds on top of the Terraform AWS Provider, and will ultimately call Unfortunately though, I believe Kubernetes + AWS don't offer any great solution to the core problem you are trying to solve. I might have expected Kubernetes to write the ARN of the load balancer back into the Service object, but it does not. And AWS does not offer a way to directly look up an LB ARN by DNS name. Moreover, I might also have expected Kubernetes to allow you to use an LB allocated outside of Kubernetes with a Service (and indeed, it seems perhaps this is an option for GCP, but not currently AWS?) so that you could create the LB with
and get its ARN, etc.. Pending Kubernetes getting better at this - the two answer I can think of are: 1. Use the JS AWS SDK or AWS CLI from Pulumi to do
to get ALL load balancers and then filter down manually to the one with the corresponding DNS name. 2. Pass the LB ARN in as config, and require a "two step" deployment where the Route53 resources are only created after that config is added, and do the
aws elb describe-load-balancers
manually outside of Pulumi.

Yup. Indeed. I was planning on approach (1) you described. Thanks for validating. I wanted to be sure I wasn't way off. Honestly it's not that big a deal to me personally to shatter that glass.
