Module classic_cluster_worker_pool

This module is used to configure a worker pool to an existing IKS cluster on IBM Cloud Infrastructure with - classic.

Example Usage

provider "ibm" {
}

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

module "classic_cluster_worker_pool" {
  //Uncomment the following line to make the source point to registry level
  //source = "terraform-ibm-modules/cluster/ibm//modules/configure-classic-worker-pool"
  source = "../../modules/configure-classic-worker-pool"

  cluster_name                    = var.cluster_name
  worker_pool_name                = var.worker_pool_name
  worker_nodes                    = var.worker_nodes
  flavor                          = var.flavor
  worker_zones                    = var.worker_zones
  resource_group_id               = data.ibm_resource_group.rg.id
  wait_till_albs                  = var.wait_till_albs
  hardware                        = var.hardware
  encrypt_local_disk              = var.encrypt_local_disk
  labels                          = var.labels
  taints                          = var.taints
  create_timeout                  = var.create_timeout
  update_timeout                  = var.update_timeout
  delete_timeout                  = var.delete_timeout
}

NOTE:

If we want to make use of a particular version of module, then set the "version" argument to respective module version.

Inputs

Name	Description	Type	Default	Required
cluster_name	Name of the cluster	string	n/a	yes
worker_nodes	Number of worker nodes.	number	n/a	yes
hardware	The level of hardware isolation for your worker node.	string	n/a	no
flavor	The machine type for your worker node.	string	n/a	yes
worker_pool_name	Name of the worker pool	string	n/a	yes
encrypt_local_disk	Set this to encrypt th elocal disk	string	n/a	no
worker_zones	List of zones to attach to a pool.	map	n/a	yes
worker_zones.public_vlan	ID of the public VLAN that we want to use for zone.	string	n/a	no
worker_zones.private_vlan	ID of the private VLAN that we want to use for zone.	string	n/a	no
resource_group	Name of the resource group.	string	n/a	no
wait_till_albs	Use to avoid long wait cluster creation time	bool	n/a	no
labels	labels to add to the worker nodes in the worker pool	map	n/a	no
create_timeout	Timeout duration for creation	string	n/a	no
update_timeout	Timeout duration for updation	string	n/a	no
delete_timeout	Timeout duration for deletion	string	n/a	no
taints	A nested block that sets or removes Kubernetes taints for all worker nodes in a worker pool	list(string)	n/a	no

taints Inputs

Name	Description	Type	Default	Required
key	Key for taint.	string	n/a	yes
value	Value for taint.	string	n/a	yes
private_endpoint	Effect for taint. Accepted values are NoSchedule, PreferNoSchedule, and NoExecute	string	n/a	yes

worker_zones Inputs

Name	Description	Type	Default	Required
public_vlan	ID of the public VLAN that we want to use for zone.	string	n/a	no
private_vlan	ID of the private VLAN that we want to use for zone.	string	n/a	no

NOTE: We can configure the list of zones to be attached to a cluster by entering zone details in input.tfvars.

Usage

terraform apply -var-file="input.tfvars"

Note

All optional fields are given value null in varaible.tf file. User can configure the same by overwriting with appropriate values.

Timeout block

Same set of timeout values (create, update & delete) are applicable to all the resources in a module. For example, say a particular module has 2 resources R1 & R2, if we configure create timeout say 90 mins then R1 create timeout will be set to 90 mins and similarly create timeout for R2 also will be set to 90 mins.
