Which solution will meet these requirements?
Configure AWS Transit Gateway to directly manage custom subnet configurations for the pods in Amazon EKS.
Create an AWS Direct Connect connection from the company’s on-premises IP address ranges to the EKS pods.
Use the Amazon VPC CNI plugin for Kubernetes. Define custom subnets in the VPC cluster for the pods to use.
Implement a Kubernetes network policy that has pod anti-affinity rules to restrict pod placement to specific nodes that are within custom subnets.
Explanations:
AWS Transit Gateway is primarily used for connecting multiple VPCs or on-premises networks to a VPC. It does not manage custom subnet configurations for EKS pods directly, which requires the Amazon VPC CNI plugin.
AWS Direct Connect is a dedicated network connection from on-premises data centers to AWS. It does not facilitate communication between EKS pods or manage pod subnets. It is meant for connecting external networks to VPCs, not for pod network configurations.
The Amazon VPC CNI plugin for Kubernetes allows for the assignment of VPC IP addresses to Kubernetes pods. By configuring custom subnets within the VPC cluster, the pods can utilize specific subnets, ensuring compliance and secure communication within the VPC.
Kubernetes network policies manage traffic between pods and can restrict communications based on labels and selectors, but they do not define the subnets in which pods run. They do not ensure that pods are assigned to custom subnets, which is the main requirement here.
I structure that the answer is:
Use the Amazon VPC CNI plugin for Kubernetes. Define custom subnets in the VPC cluster for the pods to use.
