Prompt Title: OKE load balancer IP

Certainly! Here's an example of how you can use Terraform to template an OKE Load Balancer Service with a private IP address:

1. First, create a new Terraform project and initialize it:

bashCopy code
mkdir my_oke_lb_svc
cd my_oke_lb_svc
terraform init

2. Then, define the OKE cluster and the Load Balancer Service in Terraform configuration files. Here's an example:

graphqlCopy code
provider "oci" {
  # Configure the Oracle Cloud Infrastructure provider
}

resource "oci_containerengine_cluster" "my_cluster" {
  # Define the OKE cluster
}

resource "kubernetes_service" "my_service" {
  # Define the Load Balancer Service
  metadata {
    name = "my-service"
  }

  spec {
    selector = {
      app = "my-app"
    }

    port {
      name = "http"
      port = 80
      target_port = "http"
    }

    type = "LoadBalancer"
  }
}

In this example, we are creating an OKE cluster using the oci_containerengine_cluster resource and a Load Balancer Service using the kubernetes_service resource. The Load Balancer Service is configured to listen on port 80 and forward traffic to pods labeled with app=my-app.

3. Next, we need to create a private subnet in which the Load Balancer Service will be deployed:

javaCopy code
resource "oci_core_subnet" "my_subnet" {
  # Create a private subnet for the Load Balancer Service
  cidr_block = "10.0.1.0/24"
  vcn_id     = oci_core_vcn.my_vcn.id
  dns_label = "my-subnet-dns-label"
}

resource "oci_core_vcn" "my_vcn" {
  # Create a VCN to contain the subnet
  cidr_block = "10.0.0.0/16"
  compartment_id = var.compartment_id
  display_name = "my-vcn"
}

In this example, we are creating a new Virtual Cloud Network (VCN) using the oci_core_vcn resource and a private subnet within that VCN using the oci_core_subnet resource.

4. Now, we can create the Load Balancer Service and associate it with a private IP address:

pythonCopy code
resource "kubernetes_service_load_balancer" "my_lb" {
  # Create a private IP address for the Load Balancer Service
  metadata {
    name = "my-service"
  }

  spec {
    type = "LoadBalancer"

    load_balancer_ip = oci_core_private_ip.my_lb_ip.ip_address

    selector = {
      app = "my-app"
    }

    ports {
      port = 80
      target_port = "http"
    }

    external_traffic_policy = "Local"
    load_balancer_class = "oci"
    subnet_id = oci_core_subnet.my_subnet.id
  }
}

resource "oci_core_private_ip" "my_lb_ip" {
  # Create the private IP address for the Load Balancer Service
  subnet_id = oci_core_subnet.my_subnet.id
}

In this example, we are creating a private IP address for the Load Balancer Service using the oci_core_private_ip resource and associating it with the Load Balancer Service using the kubernetes_service_load_balancer resource. The Load Balancer Service is configured to listen on port 80 and forward traffic to pods labeled with app=my-app. The subnet_id field is set to the ID of the private subnet we created in step 3.

5. Finally, we need to apply the Terraform configuration to
