aws_lambda_event_source_mapping Resource
Use the aws_lambda_event_source_mapping
InSpec audit resource to test properties of a single mapping between an AWS event source and an AWS Lambda function.
The AWS::Lambda::EventSourceMapping
resource creates a mapping between an event source and an AWS Lambda function. Lambda reads items from the event source and triggers the function.
For additional information, including details on parameters and properties, see the AWS documentation on AWS Lambda EventSourceMapping.
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 that a UUID exists.
describe aws_lambda_event_source_mapping(uuid: 'EVENT_SOURCE_MAPPING_UUID') do
it { should exist }
end
Parameters
uuid
(required)The identifier of the event source mapping.
Properties
uuid
- The identifier of the event source mapping.
starting_position
- The position in a stream from which to start reading. Required for Amazon Kinesis, Amazon DynamoDB, and Amazon MSK Streams sources.
AT_TIMESTAMP
is only supported for Amazon Kinesis streams. starting_position_timestamp
- With
StartingPosition
set toAT_TIMESTAMP
, the time from which to start reading. batch_size
- The maximum number of items to retrieve in a single batch.
maximum_batching_window_in_seconds
- (Streams and SQS standard queues) The maximum amount of time to gather records before invoking the function, in seconds. The default value is zero.
parallelization_factor
- (Streams only) The number of batches to process from each shard concurrently. The default value is 1.
event_source_arn
- The Amazon Resource Name (ARN) of the event source.
function_arn
- The ARN of the Lambda function.
last_modified
- The date that the event source mapping was last updated, or its state changed.
last_processing_result
- The result of the last AWS Lambda invocation of your Lambda function.
state
- The state of the event source mapping. It can be one of the following:
Creating
,Enabling
,Enabled
,Disabling
,Disabled
,Updating
, orDeleting
. state_transition_reason
- Indicates whether the last change to the event source mapping was made by a user, or by the Lambda service.
destination_config (on_success (destination))
- (Streams) An Amazon SQS queue or Amazon SNS topic destination for discarded records. The Amazon Resource Name (ARN) of the destination resource.
destination_config (on_failure (destination))
- The destination configuration for failed invocations. The Amazon Resource Name (ARN) of the destination resource.
topics
- The name of the Kafka topic.
queues
- (Amazon MQ) The name of the Amazon MQ broker destination queue to consume.
source_access_configurations (type)
- An array of the authentication protocol, or the VPC components to secure your event source. The type of authentication protocol or the VPC components for your event source. Valid values:
BASIC_AUTH
,SASL_SCRAM_256_AUTH
,SASL_SCRAM_512_AUTH
,VIRTUAL_HOST
,VPC_SECURITY_GROUP
,VPC_SUBNET
. source_access_configurations (uri)
- An array of the authentication protocol, or the VPC components to secure your event source. The value for your chosen configuration in Type. For example:
"URI": "arn:aws:secretsmanager:us-east-1:01234567890:secret:MyBrokerSecretName"
. maximum_record_age_in_seconds
- (Streams only) Discard records older than the specified age. The default value is infinite (-1). When set to infinite (-1), failed records are retried until the record expires.
bisect_batch_on_function_error
- (Streams only) If the function returns an error, split the batch in two and retry. The default value is false.
maximum_retry_attempts
- (Streams only) Discard records after the specified number of retries. The default value is infinite (-1). When set to infinite (-1), failed records are retried until the record expires.
Examples
Ensure an UUID is available.
describe aws_lambda_event_source_mapping(uuid: 'EVENT_SOURCE_MAPPING_UUID') do
its('uuid') { should eq 'EVENT_SOURCE_MAPPING_UUID' }
end
Ensure that the state is Creating
or not.
describe aws_lambda_event_source_mapping(uuid: 'EVENT_SOURCE_MAPPING_UUID') do
its('state') { should eq 'Creating' }
end
Matchers
For a full list of available matchers, see our Universal Matchers page.This resource has the following special matchers.
exist
Use should
to test that the entity exists.
describe aws_lambda_event_source_mapping(uuid: 'EVENT_SOURCE_MAPPING_UUID') do
it { should exist }
end
Use should_not
to test the entity does not exist.
describe aws_lambda_event_source_mapping(uuid: 'EVENT_SOURCE_MAPPING_UUID') do
it { should_not exist }
end
be_available
Use should
to check if the uuid is available.
describe aws_lambda_event_source_mapping(uuid: 'EVENT_SOURCE_MAPPING_UUID') do
it { should be_available }
end
