The problem I am trying to solve:

I want to achieve the following setup:

1. Terraform provisioned infrastructure consisting of Kubernetes cluster, DNS records pointing to that cluster,
2. Kubernetes services, deployments configured through Kubernetes .yaml files,
3. Kubernetes ingress service acting as a gateway to the services on the cluster.

How I am trying to do this:

1. Add kubernetes cluster and kubernetes ingress through Terraform. Bind kubernetes ingress IP to DNS records.
2. Deploy all the services with kubectl.

The relevant part of terraform code for this looks something like this:

resource "kubernetes_ingress" "main-ingress" {
  metadata {
    name = "main-ingress"
  }

  spec {
    rule {
      host = "service.example.com"
      http {
        path {
          backend {
            service_name = "service-name"
            service_port = 8080
          }

          path = "/"
        }
      }
    }
  }

  wait_for_load_balancer = true
}

resource "digitalocean_record" "subdomain_link" {
  domain = "example.com"
  type   = "A"
  name   = "service"
  value  = kubernetes_ingress.main-ingress.load_balancer_ingress[0].ip
}

The problem is that kubernetes_ingress does not seem to be able to be deployed without managing the pods, services and deployments through Terraform. I want to manage them separately through kubectl kustomize files.

The reason I am trying to create kubernetes ingress through Terraform is that I need the assigned IP for the DNS records in terraform.

The question I have is as follows:

Can I deploy kubernetes ingress through terraform without managing the kubernetes service through terraform?

If I can't, is there any way to know what IP will be assigned to the ingress during terraform apply so that I can bind the DNS to it?

P.S. Sorry for the convoluted question, not sure how I can structure it better.
