Typically you should not override this but you may need to if, for example, you are referencing a file that is shared across many apps and/or AWS accounts.
[[GuDistributionBucketParameter]]
Optional Readonly codeCode signing config associated with this function
- Not Sign the Code
Optional Readonly currentOptions for the lambda.Version resource automatically created by the
fn.currentVersion method.
VersionOptionsOptional Readonly deadThe SQS queue to use if DLQ is enabled.
If SNS topic is desired, specify deadLetterTopic property instead.
deadLetterQueueEnabled is trueOptional Readonly deadEnabled DLQ. If deadLetterQueue is undefined,
an SQS queue with default options will be defined for your Function.
deadLetterQueue is set, which implies DLQ is enabled.Optional Readonly deadThe SNS topic to use as a DLQ.
Note that if deadLetterQueueEnabled is set to true, an SQS queue will be created
rather than an SNS topic. Using an SNS topic as a DLQ requires this property to be set explicitly.
- no SNS topic
Optional Readonly descriptionA description of the function.
- No description.
Optional enableCreate a new Lambda version and alias. This is only necessary if you want to use features which rely on versioning (e.g. SnapStart or Provisioned Concurrency).
If you enable versioning you must ensure that your Lambda function is updated whenever a new build is deployed via
CloudFormation. The simplest way to do this is to include the build number in the fileName prop.
Optional Readonly environmentKey-value pairs that Lambda caches and makes available for your Lambda functions. Use environment variables to apply configuration changes, such as test and production environment configurations, without changing your Lambda function source code.
- No environment variables.
Optional Readonly environmentThe AWS KMS key that's used to encrypt your function's environment variables.
- AWS Lambda creates and uses an AWS managed customer master key (CMK).

We'll look for fileName on the path "bucket/stack/stage/app/
Optional Readonly filesystemThe filesystem configuration for the lambda function
- will not mount any filesystem
Optional Readonly functionA name for the function.
- AWS CloudFormation generates a unique physical ID and uses that
ID for the function's name. For more information, see Name Type.
Readonly handlerThe name of the method within your code that Lambda calls to execute your function. The format includes the file name. It can also include namespaces and other qualifiers, depending on the runtime. For more information, see https://docs.aws.amazon.com/lambda/latest/dg/foundation-progmodel.html.
Use Handler.FROM_IMAGE when defining a function from a Docker image.
NOTE: If you specify your source code as inline text by specifying the ZipFile property within the Code property, specify index.function_name as the handler.
Optional Readonly initialInitial policy statements to add to the created Lambda Role.
You can call addToRolePolicy to the created lambda to add statements post creation.
- No policy statements are added to the created Lambda role.
Optional Readonly insightsSpecify the version of CloudWatch Lambda insights to use for monitoring
When used with DockerImageFunction or DockerImageCode, the Docker image should have
the Lambda insights agent installed.
- No Lambda Insights
Optional Readonly layersA list of layers to add to the function's execution environment. You can configure your Lambda function to pull in additional code during initialization in the form of layers. Layers are packages of libraries or other dependencies that can be used by multiple functions.
- No layers.
Optional Readonly logThe number of days log events are kept in CloudWatch Logs. When updating
this property, unsetting it doesn't remove the log retention policy. To
remove the retention policy, set the value to INFINITE.
logs.RetentionDays.INFINITE
Optional Readonly logWhen log retention is specified, a custom resource attempts to create the CloudWatch log group. These options control the retry policy when interacting with CloudWatch APIs.
- Default AWS SDK retry options.
Optional Readonly logThe IAM role for the Lambda function associated with the custom resource that sets the retention policy.
- A new role is created.
Optional Readonly maxThe maximum age of a request that Lambda sends to a function for processing.
Minimum: 60 seconds Maximum: 6 hours
Duration.hours(6)
Optional Readonly memoryThe amount of memory, in MB, that is allocated to your Lambda function. Lambda uses this value to proportionally allocate the amount of CPU power. For more information, see Resource Model in the AWS Lambda Developer Guide.
128
Monitoring configuration for the lambda.
Opting-out via the NoMonitoring type is supported but discouraged.
Optional Readonly onThe destination for failed invocations.
- no destination
Optional Readonly onThe destination for successful invocations.
- no destination
Optional Readonly paramsSpecify the configuration of Parameters and Secrets Extension
- No Parameters and Secrets Extension
Optional Readonly profilingEnable profiling.

- No profiling.
Optional Readonly profilingProfiling Group.
https://docs.aws.amazon.com/codeguru/latest/profiler-ug/setting-up-lambda.html
profiling is set.Optional Readonly reservedThe maximum of concurrent executions you want to reserve for the function.
- No specific limit - account limit.
https://docs.aws.amazon.com/lambda/latest/dg/concurrent-executions.html
Optional Readonly retryThe maximum number of times to retry when the function returns an error.
Minimum: 0 Maximum: 2
2
Optional Readonly roleLambda execution role.
This is the role that will be assumed by the function upon execution. It controls the permissions that the function will have. The Role must be assumable by the 'lambda.amazonaws.com' service principal.
The default Role automatically has permissions granted for Lambda execution. If you provide a Role, you must add the relevant AWS managed policies yourself.
The relevant managed policies are "service-role/AWSLambdaBasicExecutionRole" and "service-role/AWSLambdaVPCAccessExecutionRole".
addToRolePolicy.Schedule(s) for the lambda task.
Optional description?: stringOptional description.
E.g.:
Schedule.expression("cron(0 8 ? * MON-FRI *)")Schedule.rate(Duration.minutes(5))Readonly runtimeThe runtime environment for the Lambda function that you are uploading. For valid values, see the Runtime property in the AWS Lambda Developer Guide.
Use Runtime.FROM_IMAGE when defining a function from a Docker image.
Optional Readonly runtimeSets the runtime management configuration for a function's version.
Auto
Optional Readonly securityThe list of security groups to associate with the Lambda's network interfaces.
Only used if 'vpc' is supplied.
- If the function is placed within a VPC and a security group is
not specified, either by this or securityGroup prop, a dedicated security
group will be created for this function.
Optional Readonly snapEnable SnapStart for Lambda Function. SnapStart is currently supported only for Java 11, 17 runtime
- No snapstart
Optional throttlingAlarm if throttling occurs. Note, it is also worth considering a
concurrency limit (the reservedConcurrentExecutions prop) if you are
concerned about throttling.
Optional Readonly timeoutThe function execution time (in seconds) after which Lambda terminates the function. Because the execution time affects cost, set this value based on the function's expected execution time.
Duration.seconds(3)
Optional Readonly tracingEnable AWS X-Ray Tracing for Lambda Function.
Tracing.Disabled
Optional Readonly vpcVPC network to place Lambda network interfaces
Specify this if the Lambda function needs to access resources in a VPC.
This is required when vpcSubnets is specified.
- Function is not placed within a VPC.
Optional Readonly vpcWhere to place the network interfaces within the VPC.
This requires vpc to be specified in order for interfaces to actually be
placed in the subnets. If vpc is not specify, this will raise an error.
Note: Internet access for Lambda Functions requires a NAT Gateway, so picking
public subnets is not allowed (unless allowPublicSubnet is set to true).
- the Vpc default strategy if not specified
Optional withoutSet to true this informs consumers of this function that upload is
managed elsewhere by DevX.
This is used by RiffRaffYamlFileExperimental to skip generating an uploadLambda step.
Optional withoutSet to true to use the filename without the stage/stack/app prefix.
Typically you should not override this but you may need to if, for example, you are referencing a file that is shared across many apps and/or AWS accounts.
