title: About the aws_ebs_volumes Resource
|
|
platform: aws
|
|

|

|
|
# aws\_ebs\_volumes
|
|
|
|
Use the `aws_ebs_volumes` InSpec audit resource to test properties of some or all AWS EBS volumes. To audit a single EBS volume, use `aws_ebs_volume` (singular).
|
|
|
|
EBS volumes are persistent block storage volumes for use with Amazon EC2 instances in the AWS Cloud.
|
|
|
|
Each EBS volume is uniquely identified by its ID.

## Availability
|
|
|
|
### Installation
|
|
|
|
This resource is distributed along with InSpec itself. You can use it automatically.
|
|
|
|
## Syntax
|
|
|
|
An `aws_ebs_volumes` resource block collects a group of EBS volumes and then tests that group.
|
|
|
|
# Ensure you have exactly 3 volumes
|
|
describe aws_ebs_volumes do
|
|
its('volume_ids.count') { should cmp 3 }
|
|
end
|
|
|
|
# Use the InSpec resource to enumerate IDs, then test in-depth using `aws_ebs_volume`.
|
|
aws_ebs_volumes.volume_ids.each do |volume_id|
|
|
describe aws_ebs_volume(volume_id) do
|
|
it { should exist }
|
|
it { should be_encrypted }
|
|
its('size') { should cmp 8 }
|
|
its('iops') { should cmp 100 }
|
|
end
|
|
end
|
|
|
|
<br>
|
|
|
|
## Examples
|
|
|
|
As this is the initial release of `aws_ebs_volumes`, its limited functionality precludes examples.
|
|
|

|
|
|
## Filter Criteria
|
|
|
|
This resource currently does not support any filter criteria; it will always fetch all volumes in the region.
|
|
|
|
## Properties
|
|
|
|
### entries
|
|
|
|
Provides access to the raw results of the query, which can be treated as an array of hashes. This can be useful for checking counts and other advanced operations.
|
|
|
|
# Allow at most 100 EBS volumes on the account
|
|
describe aws_ebs_volumes do
|
|
its('entries.count') { should be <= 100 }
|
|
end
|
|
|
|
### volume_ids
|
|
|
|
Provides a list of the volume ids that were found in the query.
|
|
|
|
describe aws_ebs_volumes do
|
|
its('volume_ids') { should include 'vol-12345678' }
|
|
its('volume_ids.count') { should cmp 3 }
|
|
end
|
|
|
|

|
## Matchers
|
|
|
|
For a full list of available matchers, please visit our [Universal Matchers page](https://www.inspec.io/docs/reference/matchers/).
|
|
|
|
### exist
|
|
|
|
The control will pass if the filter returns at least one result. Use `should_not` if you expect zero matches.
|
|
|
|
# Verify that at least one EBS volume exists
|
|
describe aws_ebs_volumes do
|
|
it { should exist }
|
|
end
|
