# Overview

In this exercise, you will learn how to use the controller to configure and provision an Amazon EKS Cluster with Custom Networking. You will then deploy a containerized application to the EKS cluster with the pods getting deployed to the host and pod network.

## What Will You Do by Part [¶](https://docs.rafay.co/learn/quickstart/eks/custom_networking/overview/#what-will-you-do-by-part "Permanent link")

| Part | What will you do? |
| --- | --- |
| 1 | [Configure and Provision](https://docs.rafay.co/learn/quickstart/eks/custom_networking/provision/) an AWS EKS Cluster with Custom Networking |
| 2 | Deploy a [Workload](https://docs.rafay.co/learn/quickstart/eks/custom_networking/workload/) using Custom Networking |
| 3 | Deprovision the EKS cluster |

## Assumptions [¶](https://docs.rafay.co/learn/quickstart/eks/custom_networking/overview/#assumptions "Permanent link")

- You have access to an [Amazon AWS account](https://aws.amazon.com/) with privileges to create an IAM Role with the default [Full IAM Policy](https://docs.rafay.co/clusters/eks/full_iam_policy/) to allow provisioning of resources on your behalf as part of the EKS cluster lifecycle. Steps to create the IAM Role can be found [here.](https://docs.rafay.co/clusters/eks/credentials_clusterprovisioning/)
- You have installed and configured the [RCTL CLI](https://docs.rafay.co/cli/config/) so that you can perform the tasks with automation and declarative cluster specification files.
- You have created a [Cloud Credential](https://docs.rafay.co/clusters/eks/credentials/) using the ARN of the AWS IAM Role created above in the project "defaultproject".
- You have attached a secondary CIDR block from the 100.64.0.0/10 or 198.19.0.0/16 ranges to your VPC.
- You have created subnets from the secondary CIDR block.

## VPC Configuration [¶](https://docs.rafay.co/learn/quickstart/eks/custom_networking/overview/#vpc-configuration "Permanent link")

Use the following VPC configuration as a reference to the following cluster spec.

| Name | Subnet-Id | CIDR | AZ |
| --- | --- | --- | --- |
| SecondarySubnetPrivateUSWEST2A | subnet-081ff5e370607fafa | 100.64.0.0/20 | us-west-2a |
| SecondarySubnetPrivateUSWEST2B | subnet-0d336d3350d55a986 | 100.64.16.0/20 | us-west-2c |
