Hi friends, we have a VPC using Ipv4 only, this vpc is used by our EKS cluster. We worry that we may not be able to scale the number of nodes due to the limited number of available IPv4 addresses left on our subnets. What should we do in this case?
Our VPC is setup using terraform
source = "terraform-aws-modules/vpc/aws"
version = "2.78.0"
name = local.vpc_name
cidr = "10.0.0.0/16"
azs = data.aws_availability_zones.available.names
private_subnets = ["10.0.1.0/24", "10.0.2.0/24", "10.0.3.0/24"]
public_subnets = ["10.0.4.0/24", "10.0.5.0/24", "10.0.6.0/24"]
enable_nat_gateway = true
single_nat_gateway = true
enable_dns_hostnames = true
tags = {
Terraform = "true"
Environment = local.workspace
}
}```
