How to connect an EFS storage class to an EKS cluster

Shawn Sesna shares his experience of configuring the Octopus Kubernetes agent on an AWS Elastic Kubernetes Service (EKS) cluster using the Elastic File System (EFS) for the storage class. Finding the process challenging due to scattered documentation, he provides a concise guide to streamline the integration of EFS with EKS. The post assumes the reader has an EKS cluster and recommends using the eksctl tool for setup. It details steps for creating an EFS file system, setting up an IAM OIDC provider, and creating an IAM Service Account and Role for the CSI driver. Sesna also describes adding the Amazon EFS CSI Driver to the cluster and creating a StorageClass resource. He addresses potential troubleshooting issues, such as permission errors, and aims to assist others by consolidating the necessary steps in one location, thereby alleviating the frustration of navigating through dispersed AWS documentation.
