EKS EBS CSI Driver Module

View SourceRelease Notes

This Terraform module installs the Amazon EBS CSI Driver to an EKS cluster as an EKS Managed AddOn. The EBS CSI Driver manages the lifecycle of EBS Volumes when used as Kubernetes Volumes. The EBS CSI Driver is enabled by default in EKS clusters >= 1.23, but not installed. The EBS CSI Driver was installed by default on earlier versions of EKS. This module will create all of the required resources to run the EBS CSI Driver and can be configured as needed without the bounds of the EBS CSI Driver as a Managed AddOn. See the official documentation for more details.

This module is exposed directly on the eks-cluster-control module as with the other available EKS AddOns, but this module can also be used independently by toggling the enable_ebs_csi_driver to false (false by default on the eks-control-plane module) on the eks-control-plane module and instead declaring this module elsewhere within the codebase.

NOTE: currently enabling/deploying this module in a new cluster will take ~15 mins to deploy due to a limitation on the AWS side. The health status of the AddOn itself isn't reported in a timely manner which causes the deployment to take extra time even though the AddOn is deployed and healthy. Please be aware of this as it will increase the initial deployment time of a new EKS cluster.

Reference

Required

eks_cluster_namestringrequired

The name of the EKS cluster to create the AWS EKS EBS CSI Driver in.

ARN of the OpenID Connect Provider provisioned for the EKS cluster.

URL of the OpenID Connect Provider provisioned for the EKS cluster.

Optional

Configuraiton object for the EBS CSI Driver EKS AddOn

Any types represent complex values of variable type. For details, please consult `variables.tf` in the source repo.
{}
Details

EKS add-on advanced configuration via configuration_values must follow the configuration schema for the deployed version of the add-on.
See the following AWS Blog for more details on advanced configuration of EKS add-ons: https://aws.amazon.com/blogs/containers/amazon-eks-add-ons-advanced-configuration/
Example:
{
addon_version = "v1.14.0-eksbuild.1"
configuration_values = {}
preserve = false
resolve_conflicts = "NONE"
service_account_role_arn = "arn:aws:iam::123456789012:role/role-name"
}

ebs_csi_driver_addon_tagsmap(string)optional

A map of custom tags to apply to the EBS CSI Driver AddOn. The key is the tag name and the value is the tag value.

{}
Example
     {
key1 = "value1"
key2 = "value2"
}

If using KMS encryption of EBS volumes, provide the KMS Key ARN to be used for a policy attachment.
