machine-pool

Introduction

This Terraform sub-module manages the machine pool for ROSA HCP clusters. It enables you to efficiently configure and scale machine pools after cluster deployment, ensuring optimal resource allocation and performance for workloads within the ROSA HCP cluster environment. With this module, you can easily adjust the size and specifications of machine pools, facilitating seamless adaptation to changing workload demands and operational requirements in ROSA HCP clusters.

Example Usage

module "mp" {
  source = "terraform-redhat/rosa-hcp/rhcs//modules/machine-pool"
  version = "1.6.2"

  cluster_id = "cluster-id-123"
  name = "my-pool"
  openshift_version = "my-version"

  aws_node_pool = {
    instance_type = "my-instance"
    tags = {}
  }

  subnet_id = "subnet-123"
  autoscaling = {
    enabled = false
    min_replicas = null
    max_replicas = null
  }
  replicas = 2
}

Inputs

Name	Description	Type	Default	Required
auto_repair	Configures auto repair option for the pool.	bool	true	no
autoscaling	Configures autoscaling for the pool.	object({ enabled = bool min_replicas = number max_replicas = number })	{ "enabled": false, "max_replicas": null, "min_replicas": null }	no
aws_node_pool	Configures aws settings for the pool.	object({ instance_type = string tags = map(string) additional_security_group_ids = list(string) })	n/a	yes
cluster_id	Identifier of the cluster.	string	n/a	yes
ignore_deletion_error	Ignore machine pool deletion error. Assists when cluster resource is managed within the same file for the destroy use case	bool	false	no
kubelet_configs	Name of the kubelet configs to attach to this machine pool. The kubelet configs must already exist	string	null	no
labels	Labels for the machine pool. Format should be a comma-separated list of 'key = value'. This list will overwrite any modifications made to node labels on an ongoing basis.	map(string)	null	no
name	Name of the machine pool. Must consist of lower-case alphanumeric characters or '-', start and end with an alphanumeric character.	string	n/a	yes
openshift_version	Desired version of OpenShift for the cluster, for example '4.1.0'. If version is greater than the currently running version, an upgrade will be scheduled.	string	n/a	yes
replicas	The amount of the machine created in this machine pool.	number	null	no
subnet_id	Select the subnet in which to create a single AZ machine pool for BYO-VPC cluster	string	n/a	yes
taints	Taints for a machine pool. This list will overwrite any modifications made to node taints on an ongoing basis.	list(object({ key = string value = string schedule_type = string }))	null	no
tuning_configs	A list of tuning config names to attach to this machine pool. The tuning configs must already exist	list(string)	null	no
upgrade_acknowledgements_for	Indicates acknowledgement of agreements required to upgrade the cluster version between minor versions (e.g. a value of "4.12" indicates acknowledgement of any agreements required to upgrade to OpenShift 4.12.z from 4.11 or before).	string	null	no
