title: About the aws_rds_instance Resource

# aws\_rds\_instance
|
|
|
|
Use the `aws_rds_instance` Chef InSpec audit resource to test detailed properties of an individual RDS instance.
|
|
|
|
RDS gives you access to the capabilities of a MySQL, MariaDB, PostgreSQL, Microsoft SQL Server, Oracle, or Amazon Aurora database server.

|
## Availability
|
|
|
|
### Installation
|
|
|
|
This resource is distributed along with Chef InSpec itself. You can use it automatically.
|
|
|
|
### Version
|
|
|
|
This resource first became available in v2.1.21 of InSpec.
|
|
|
|
## Syntax
|
|
|
|
An `aws_rds_instance` resource block uses resource parameters to search for an RDS instance, and then tests that RDS instance. If no RDS instances match, no error is raised, but the `exists` matcher will return `false` and all properties will be `nil`. If more than one RDS instance matches (due to vague search parameters), an error is raised.
|
|
|
|
# Ensure you have a RDS instance with a certain ID
|
|
# This is "safe" - RDS IDs are unique within an account
|
|
describe aws_rds_instance('test-instance-id') do
|
|
it { should exist }
|
|
end
|
|
|
|
# Ensure you have a RDS instance with a certain ID
|
|
# This uses hash syntax
|
|
describe aws_rds_instance(db_instance_identifier: 'test-instance-id') do
|
|
it { should exist }
|
|
end
|
|
|
|

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

|
As this is the initial release of `aws_rds_instance`, its limited functionality precludes examples.

## Resource Parameters
|
|
|
|
This Chef InSpec resource accepts the following parameters, which are used to search for the RDS instance.
|
|
|
|
### exists
|
|
|
|
The control will pass if the specified RDS instance was found. Use should_not if you want to verify that the specified RDS instance does not exist.
|
|
|
|
# Using Hash syntax
|
|
describe aws_rds_instance(db_instance_identifier: 'test-instance-id') do
|
|
it { should exist }
|
|
end
|
|
|
|
# Using the instance id directly from the terraform file
|
|
describe aws_rds_instance(fixtures['rds_db_instance_id']) do
|
|
it { should exist }
|
|
end
|
|
|
|
# Make sure we don't have any RDS instances with the name 'nogood'
|
|
describe aws_rds_instance('nogood') do
|
|
it { should_not exist }
|
|
end
|
|
