## Resource Parameters

An `aws_eks_cluster` resource block declares the tests for a single EKS Cluster by Cluster name.

    describe aws_eks_cluster('my-eks') do
      it { should exist }
    end

    describe aws_eks_cluster(cluster_name: 'my-eks') do

## Examples

The following examples show how to use this Chef InSpec audit resource.

### Test that an EKS Cluster does not exist

    describe aws_eks_cluster('bad-eks') do
      it { should_not exist }
    end

    describe aws_eks_cluster('my-cluster') do
      its('subnets_count') { should be > 1 }
    end
