+Description: |-
+    Reading the EKS cluster resource managed by Tanzu Mission Control.
+---
+
+# EKS Cluster
+
+The `tanzu-mission-control_ekscluster` resource allows you to provision and manage [AWS EKS](https://aws.amazon.com/eks/) through Tanzu Mission Control.
+It allows users to connect Tanzu Mission Control to their Amazon Web Services (AWS) account and create, update/upgrade, and delete EKS clusters and node groups (called node pools in Tanzu).
+
+## Provisioning an EKS Cluster
+
+To use the **Tanzu Mission Control** for creating a new cluster, you must first connect your AWS account to Tanzu Mission Control.
+For more information, see [connecting an AWS account for EKS cluster lifecycle management][aws-account]
+and [create an EKS Cluster][create-cluster].
+
+You must also have the appropriate permissions in Tanzu Mission Control:
+
+- To provision a cluster, you must have `cluster.admin` permissions.
+- You must also have `clustergroup.edit` permissions on the cluster group in which you want to put the new cluster.
