The blog post discusses setting up and using the Amazon Elastic File System (EFS) Container Storage Interface (CSI) Driver with Kubernetes workloads on Amazon EKS using Pulumi libraries. It outlines the process of installing the Pulumi CLI, initializing a new project, and creating two Pulumi stacks: one for the EKS cluster and EFS components, and another for the application and its storage resources. The post details steps to create an EKS cluster, configure an EFS endpoint and mount targets, install the EFS CSI Driver components, and deploy a sample application using the EFS volume mounts. The approach ensures high availability and durability by storing data across multiple Availability Zones, leveraging the EFS CSI Driver as a Kubernetes SIG-AWS subproject, and utilizing Pulumi's infrastructure-as-code capabilities to automate the setup.
