For additional information, including details on parameters and properties, see the AWS documentation on EBS.

Installation

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

See the Chef InSpec documentation on cloud platforms for information on configuring your AWS environment for InSpec and creating an InSpec profile that uses the InSpec AWS resource pack.

Syntax

Ensure you have exactly three volumes.

describe aws_ebs_volumes do
  its('VOLUME_ID_COUNT') { should cmp 3 }
end

Examples

Ensure a specific volume exists.

describe aws_ebs_volumes do
  its('VOLUME_IDs') { should include 'VOLUME-12345678' }
end

Request the EBS volumes IDs.

Test in-depth using aws_ebs_volume to ensure all volumes are encrypted and have a sensible size.

aws_ebs_volumes.volume_ids.each do |volume_id|
  describe aws_ebs_volume(volume_id) do
    it          { should be_encrypted }
    its('size') { should be > 10 }
    its('iops') { should cmp 100 }
  end
end
