Unable to deploy EKS cluster

Cloud AWS
#1

Hi,

When I try to deploy the EKS cluster with the nodes, following the same article

It gives me the following errors, it was working fine earlier

It looks like the error is due to the fact that data.aws_subnets.public.ids only contains one element, but the code is trying to access three elements. but EKS needs to deploy in three availability zones

eks.tf

vpc_config {
subnet_ids = [
data.aws_subnets.public.ids[0],
data.aws_subnets.public.ids[1],
data.aws_subnets.public.ids[2]
]
}
