EKS Permissions

EKS actions require some additional IAM configuration to create a cluster and access it.

Overview

• EKS clusters need an associated service-linked EKS Role to access other AWS services. If such a role does not already exist in the account, Create EKS Role provides instructions on how to create it.

• The Target Account requires some privileges beyond PowerUserAccess to use EKS actions. Add Inline Policy to Target Account provides instructions on how to add these privileges. Using Service-Linked Roles for Amazon EKS - Amazon EKS provides more detail on this requirement.

Managing existing Kubernetes cluster with Fylamynt

• If you want to use an existing Kubernetes (k8s) cluster, you must allow one of your Fylamynt Target Accounts (AWS account configured) to access the k8s cluster. This can be done by associating a Target Account (AWS account configured) role ARN with a list of K8s groups (i.e. system:masters, system:basic-user). Please follow the instruction in Managing users or IAM roles for your cluster - Amazon EKS to complete this process.
