handler
Type:
string
The 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.
runtime
Type:
Runtime
The 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.

Type:
Adot
(optional, default: No ADOT instrumentation)
Specify the configuration of AWS Distro for OpenTelemetry (ADOT) instrumentation.
See also: https://aws-otel.github.io/docs/getting-started/lambda
allowAllIpv6Outbound?
Type:
boolean
(optional, default: false)
Whether to allow the Lambda to send all ipv6 network traffic.
If set to true, there will only be a single egress rule which allows all outbound ipv6 traffic. If set to false, you must individually add traffic rules to allow the Lambda to connect to network targets using ipv6.
Do not specify this property if the securityGroups
or securityGroup
property is set.
Instead, configure allowAllIpv6Outbound
directly on the security group.

Type:
ITopic
(optional, default: no SNS topic)
The 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.

Type:
string
(optional, default: No description.)
A description of the function.
environment?
Type:
{ [string]: string }
(optional, default: No environment variables.)

You can also add event sources using addEventSource
.
executeAfter?
Type:
Construct
[]
(optional, default: [])

You can also use trigger.executeAfter()
to add additional dependencies.
executeBefore?
Type:
Construct
[]
(optional, default: [])
Adds this trigger as a dependency on other constructs.
This means that this trigger will get executed before the given construct(s).
You can also use trigger.executeBefore()
to add additional dependants.
executeOnHandlerChange?
Type:
boolean

of
the handler, which gets recreated every time the handler or its
configuration is updated.
filesystem?
Type:
File
(optional, default: will not mount any filesystem)
The filesystem configuration for the lambda function.
functionName?
Type:
string
(optional, default: AWS CloudFormation generates a unique physical ID and uses that
ID for the function's name. For more information, see Name Type.)
A name for the function.
initialPolicy?
Type:

Allows outbound IPv6 traffic on VPC functions that are connected to dual-stack subnets.
Only used if 'vpc' is supplied.
layers?
Type:
ILayer
[]
(optional, default: No layers.)
A 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.
logFormat?
⚠️ Deprecated: Use loggingFormat
as a property instead.
Type:
string
(optional, default: "Text")
Sets the logFormat for the function.
logGroup?
Type:
ILog
(optional, default: /aws/lambda/${this.functionName}
- default log group created by Lambda)
The log group the function sends logs to.
By default, Lambda functions send logs to an automatically created default log group named /aws/lambda/<function name>. However you cannot change the properties of this auto-created log group using the AWS CDK, e.g. you cannot set a different log retention.
Use the logGroup
property to create a fully customizable LogGroup ahead of time, and instruct the Lambda function to send logs to it.
Providing a user-controlled log group was rolled out to commercial regions on 2023-11-16. If you are deploying to another type of region, please check regional availability first.
logRetention?
Type:
Retention
(optional, default: logs.RetentionDays.INFINITE)
The 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
.
This is a legacy API and we strongly recommend you move away from it if you can.
Instead create a fully customizable log group with logs.LogGroup
and use the logGroup
property
to instruct the Lambda function to send logs to it.
Migrating from logRetention
to logGroup
will cause the name of the log group to change.
Users and code and referencing the name verbatim will have to adjust.
In AWS CDK code, you can access the log group name directly from the LogGroup construct:
import * as logs from 'aws-cdk-lib/aws-logs';
declare const myLogGroup: logs.LogGroup;
myLogGroup.logGroupName;
logRetentionRetryOptions?
Type:
Log
(optional, default: Default AWS SDK retry options.)
When 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.
This is a legacy API and we strongly recommend you migrate to logGroup
if you can.
logGroup
allows you to create a fully customizable log group and instruct the Lambda function to send logs to it.
logRetentionRole?
Type:
IRole
(optional, default: A new role is created.)
The IAM role for the Lambda function associated with the custom resource that sets the retention policy.
This is a legacy API and we strongly recommend you migrate to logGroup
if you can.
logGroup
allows you to create a fully customizable log group and instruct the Lambda function to send logs to it.
loggingFormat?
Type:
Logging
(optional, default: LoggingFormat.TEXT)
Sets the loggingFormat for the function.
maxEventAge?
Type:
Duration
(optional, default: Duration.hours(6))

Minimum: 60 seconds Maximum: 6 hours
memorySize?
Type:
number
(optional, default: 128)
The amount of memory, in MB, that is allocated to your Lambda function.

role?
Type:
IRole
(optional, default: A unique role will be generated for this lambda function.
Both supplied and generated roles can always be changed by calling addToRolePolicy
.)
Lambda 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".
runtimeManagementMode?
Type:
Runtime
(optional, default: Auto)
Sets the runtime management configuration for a function's version.

The 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.
tracing?
Type:
Tracing
(optional, default: Tracing.Disabled)
Enable AWS X-Ray Tracing for Lambda Function.
vpc?
Type:
IVpc
(optional, default: Function is not placed within a VPC.)
VPC 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.
vpcSubnets?
Type:
Subnet
(optional, default: the Vpc default strategy if not specified)
Where 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
).
