aws_rds_clusters Resource

Use the aws_rds_clusters InSpec audit resource to test properties of a collection of AWS RDS clusters.

RDS gives you access to the capabilities of a MySQL, MariaDB, PostgreSQL, Microsoft SQL Server, Oracle, or Amazon Aurora database server.

Install

This resource is available in the Chef InSpec AWS resource pack.

For information on configuring your AWS environment for Chef InSpec and creating an InSpec profile that uses the InSpec AWS resource pack, see the Chef InSpec documentation on the AWS cloud platform.

Syntax

Ensure you have exactly 3 clusters

describe aws_rds_clusters do
  its('db_cluster_identifiers.count') { should cmp 3 }
end

Parameters

This resource does not require any parameters.

Properties

cluster_identifier

The unique IDs of the RDS clusters returned.

database_name

The name of the database associated with each RDS cluster.

cluster_\members

The RDS instances attached to each RDS cluster.

engine

The name of the database engine used by each cluster.

engine_version

Examples

Ensure a specific cluster exists.

describe aws_rds_clusters do
  its('db_cluster_identifier') { should include ['cluster-12345678', 'cluster-456786786'] }
end

Request the IDs of all RDS clusters, then test in-depth using aws_rds_cluster to ensure all clusters are encrypted and have a sensible size.

aws_rds_clusters.cluster_identifier.each do |cluster_identifier|
    describe aws_rds_cluster(cluster_identifier) do
      it { should have_encrypted_storage }
  end
end

Matchers

This resource has the following special matchers.

exist

The control will pass if the describe returns at least one result.

Use should_not to test the entity should not exist.

describe aws_rds_clusters do
  it { should exist }
end

describe aws_rds_clusters do
  it { should_not exist }
end
