IBM VPC Classic Cluster example

This example shows how to create a Kubernetes VPC Cluster under a specified resource group id, with default worker node with given zone and subnets. To have a multizone cluster, update the zones with new zone-name and subnet-id.

Following types of resources are supported:

• VPC Classic Cluster Resource

Usage

To run this example you need to execute:

$ terraform init
$ terraform plan
$ terraform apply

Run terraform destroy when you don't need these resources.

Example Usage

Create a container cluster:

resource "ibm_is_vpc" "vpc1" {
  name = "vpc"
}

data "ibm_resource_group" "resource_group" {
  name = var.resource_group
}

resource "ibm_is_subnet" "subnet1" {
  name                     = "subnet-1"
  vpc                      = ibm_is_vpc.vpc1.id
  zone                     = "us-south-1"
  total_ipv4_address_count = 256
}

resource "ibm_resource_instance" "kms_instance1" {
    name              = "test_kms"
    service           = "kms"
    plan              = "tiered-pricing"
    location          = "us-south"
}

resource "ibm_kms_key" "test" {
    instance_id = "${ibm_resource_instance.kms_instance1.guid}"
    key_name = "test_root_key"
    standard_key =  false
    force_delete = true
}

resource "ibm_container_vpc_cluster" "cluster" {
  name              = var.name
  vpc_id            = ibm_is_vpc.vpc1.id
  flavor            = var.flavor
  worker_count      = var.worker_count
  resource_group_id = data.ibm_resource_group.resource_group.id

  zones {
    subnet_id = ibm_is_subnet.subnet1.id
    name      = "us-south-1"
  }

  kms_config {
    instance_id = ibm_resource_instance.kms_instance1.guid
    crk_id = ibm_kms_key.test.id
    private_endpoint = false
  }

}

data "ibm_container_vpc_cluster" "cluster" {
  cluster_name_id   = "vpccluster"
  resource_group_id = data.ibm_resource_group.group.id
}
