This is a collection of modules that make it easier to provision a cluster on IBM Cloud Platform:
- classic-kubernetes-multi-zone-cluster
- classic-kubernetes-single-zone-cluster
- classic-openshift-multi-zone-cluster
- classic-openshift-single-zone-cluster
- vpc-kubernetes-cluster
- vpc-openshift-cluster
- classic-free-cluster
And it also has the following modules to configure a already provisioned cluster in IBM Cloud Platform:
This module is meant for use with Terraform 0.12. If you haven't [upgraded][terraform-0.12-upgrade] and need a Terraform 0.11.x-compatible version of this module, the last released version intended for Terraform 0.11.x is [1.1.1][v1.1.1].
Full examples are in the examples folder, but basic usage is as follows for creation of classic cluster with single zone:
provider "ibm" {
}
data "ibm_resource_group" "test" {
name = var.resource_group
}
module "classic_kubernetes_single_zone_cluster" {
source = "../../modules/classic-kubernetes-single-zone-cluster"
cluster_name = var.cluster_name
resource_group_id = data.ibm_resource_group.test.id
worker_zone = var.worker_zone
worker_nodes_per_zone = var.worker_nodes_per_zone
worker_pool_flavor = var.worker_pool_flavor
public_vlan = var.public_vlan_id
private_vlan = var.private_vlan_id
hardware = var.hardware
master_service_public_endpoint = var.master_service_public_endpoint
master_service_private_endpoint = var.master_service_private_endpoint
}
Creation of vpc openshift cluster:
provider "ibm" {
generation = var.generation
}
data "ibm_resource_group" "test" {
name = var.resource_group
}
module "vpc_openshift_cluster" {
source = "../../modules/vpc-openshift-cluster"
cluster_name = var.cluster_name
resource_group_id = data.ibm_resource_group.test.id
vpc_id = var.vpc_id
cos_instance_crn = var.cos_instance_crn
worker_pool_flavor = var.worker_pool_flavor
worker_nodes_per_zone = var.worker_nodes_per_zone
sunet_id = var.sunet_id
zone_name = var.zone_name
}Be sure you have the correct Terraform version (0.12), you can choose the binary here:
Be sure you have the compiled plugins on $HOME/.terraform.d/plugins/
To review the plan for the configuration defined (no resources actually provisioned)
terraform plan -var-file=./input.tfvars
To execute and start building the configuration defined in the plan (provisions resources)
terraform apply -var-file=./input.tfvars
To destroy the VPC and all related resources
terraform destroy -var-file=./input.tfvars
All optional parameters by default will be set to null in respective example's varaible.tf file. If user wants to configure any optional paramter he has overwrite the default value.
All optional fields should be given value null in respective resource varaible.tf file. User can configure the same by overwriting with appropriate values.
