 1. You can use an existing EKS cluster or create a new one as shown here:

    ```
 1. Configure security group: To receive traffic from the VPC Lattice fleet, you must set up security groups so that they allow all Pods communicating with VPC Lattice to allow traffic on all ports from the 169.254.171.0/24 address range. See [Control traffic to resources using security groups](https://docs.aws.amazon.com/vpc/latest/userguide/VPC_SecurityGroups.html) for details.
