aws_subnets tags resources returns a nested list

[edmeister]

Describe the problem

I try to test if certain tags have been set on my subnets, but unfortunately, the tags property returns a nested list, making it rather impossible to test if a certain tag is in it.

Test code:

vpc_private_subnet_ids = attribute('vpc_private_subnet_ids', description: 'private subnet ids')

control 'vpc' do
  vpc_private_subnet_ids.each do |subnet_id|
    describe aws_subnets.where(subnet_id: subnet_id) do
      its('tags') { should include({key: 'kubernetes.io/cluster/test-cluster1', value: 'shared'}) }
    end
  end
end

(Redacted) output of the test:

 ×  aws_subnets with subnet_id == "subnet-0****6" tags is expected to include {:key => "kubernetes.io/cluster/test-cluster1", :value => "shared"}
     expected [[{:key => "Ext_access", :value => "true"}, {:key => "Name", :value => "********-1...hared"}, {:key => "Public", :value => "false"}, {:key => "kubernetes.io/role/internal-elb", :value => "1"}]] to include {:key => "kubernetes.io/cluster/test-cluster1", :value => "shared"}

Possible Solution

The tags property should be a simple list containing the key-value pairs. This will allow us to test resources with multiple tags.
