IRSA in EKS within same and across AWS Accounts

This is a gist of examples also mentioned in the blog IAM Roles for Service Accounts (IRSA) in AWS EKS within and cross AWS Accounts. Prerequisite for this gist is to create the EKS Cluster as explained in my earlier blog Create Amazon EKS Cluster within its VPC using Terraform, OR you can use this github repository.

Running Example for IRSA within same account

Assuming you have the EKS Cluster running and your AWS CLI is configured to talk to the AWS Account where your EKS Cluster is running. If not please follow the our earlier blog on How to create an EKS Cluster using Terraform
