public readonly env: ResourceEnvironment;
  • Type: aws-cdk-lib.ResourceEnvironment

The environment this resource belongs to.

For resources that are created and managed by the CDK (generally, those created by creating new class instances like Role, Bucket, etc.), this is always the same as the environment of the stack they belong to; however, for imported resources (those obtained from static methods like fromRoleArn, fromBucketName, etc.), that might be different than the stack they were imported into.

stackRequired 
public readonly stack: Stack;
  • Type: aws-cdk-lib.Stack

The stack in which this resource is defined.

architectureRequired 
public readonly architecture: Architecture;
  • Type: aws-cdk-lib.aws_lambda.Architecture

If this is is false, trying to access the connections object will fail.

latestVersionRequired 
public readonly latestVersion: IVersion;
  • Type: aws-cdk-lib.aws_lambda.IVersion

The $LATEST version of this function.

Note that this is reference to a non-specific AWS Lambda version, which means the function this version refers to can return different results in different invocations.

To obtain a reference to an explicit version which references the current function configuration, use lambdaFunction.currentVersion instead.

permissionsNodeRequired 
public readonly permissionsNode: Node;
  • Type: constructs.Node

The construct node where permissions are attached.

resourceArnsForGrantInvokeRequired 
public readonly resourceArnsForGrantInvoke: string[];

Execution role associated with this function.

currentVersionRequired 
public readonly currentVersion: Version;
  • Type: aws-cdk-lib.aws_lambda.Version

Returns a lambda.Version which represents the current version of this Lambda function. A new version will be created every time the function's configuration changes.

You can specify options for this version using the currentVersionOptions prop when initializing the lambda.Function.

logGroupRequired 
public readonly logGroup: ILogGroup;
  • Type: aws-cdk-lib.aws_logs.ILogGroup

The LogGroup where the Lambda function's logs are made available.

If either logRetention is set or this property is called, a CloudFormation custom resource is added to the stack that pre-creates the log group as part of the stack deployment, if it already doesn't exist, and sets the correct log retention period (never expire, by default).

Further, if the log group already exists and the logRetention is not set, the custom resource will reset the log retention to never expire even if it was configured with a different value.

runtimeRequired 
public readonly runtime: Runtime;
  • Type: aws-cdk-lib.aws_lambda.Runtime

The runtime configured for this lambda.

deadLetterQueueOptional 
public readonly deadLetterQueue: IQueue;

The DLQ (as queue) associated with this Lambda Function (this is an optional attribute).

deadLetterTopicOptional 
public readonly deadLetterTopic: ITopic;
  • Type: aws-cdk-lib.aws_sns.ITopic

The DLQ (as topic) associated with this Lambda Function (this is an optional attribute).

The filesystem configuration for the lambda function.

functionNameOptional 
public readonly functionName: string;
  • Type: string
  • 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.

initialPolicyOptional 
public readonly initialPolicy: PolicyStatement[];
  • Type: aws-cdk-lib.aws_iam.PolicyStatement[]
  • Default: No policy statements are added to the created Lambda role.

Initial policy statements to add to the created Lambda Role.

You can call addToRolePolicy to the created lambda to add statements post creation.

public readonly insightsVersion: LambdaInsightsVersion;
  • Type: aws-cdk-lib.aws_lambda.LambdaInsightsVersion
  • Default: No Lambda Insights

Specify the version of CloudWatch Lambda insights to use for monitoring.

layersOptional 
public readonly layers: ILayerVersion[];
  • Type: aws-cdk-lib.aws_lambda.ILayerVersion[]
  • 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.

logRetentionOptional 
public readonly logRetention: RetentionDays;
  • Type: aws-cdk-lib.aws_logs.RetentionDays
  • 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.

logRetentionRetryOptionsOptional 
public readonly logRetentionRetryOptions: LogRetentionRetryOptions;
  • Type: aws-cdk-lib.aws_lambda.LogRetentionRetryOptions
  • 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.

logRetentionRoleOptional 
public readonly logRetentionRole: IRole;
  • Type: aws-cdk-lib.aws_iam.IRole
  • Default: A new role is created.

The IAM role for the Lambda function associated with the custom resource that sets the retention policy.

memorySizeOptional 
public readonly memorySize: number;
  • Type: number
  • Default: 128

The 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.

profilingOptional 
public readonly profiling: boolean;
  • Type: boolean
  • Default: No profiling.

Enable profiling.

https://docs.aws.amazon.com/codeguru/latest/profiler-ug/setting-up-lambda.html

profilingGroupOptional 
public readonly profilingGroup: IProfilingGroup;
  • Type: aws-cdk-lib.aws_codeguruprofiler.IProfilingGroup
  • Default: A new profiling group will be created if profiling is set.

Profiling Group.

https://docs.aws.amazon.com/codeguru/latest/profiler-ug/setting-up-lambda.html

reservedConcurrentExecutionsOptional 
public readonly reservedConcurrentExecutions: number;
  • Type: number
  • Default: No specific limit - account limit.

The maximum of concurrent executions you want to reserve for the function.

https://docs.aws.amazon.com/lambda/latest/dg/concurrent-executions.html

roleOptional 
public readonly role: IRole;
  • Type: aws-cdk-lib.aws_iam.IRole
  • 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".

securityGroupsOptional 
public readonly securityGroups: ISecurityGroup[];
  • Type: aws-cdk-lib.aws_ec2.ISecurityGroup[]
  • Default: 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.

The list of security groups to associate with the Lambda's network interfaces.

Only used if 'vpc' is supplied.

timeoutOptional 
public readonly timeout: Duration;
  • Type: aws-cdk-lib.Duration
  • Default: Duration.seconds(3)

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.

tracingOptional 
public readonly tracing: Tracing;
  • Type: aws-cdk-lib.aws_lambda.Tracing
  • Default: Tracing.Disabled

Enable AWS X-Ray Tracing for Lambda Function.

vpcOptional 
public readonly vpc: IVpc;
  • Type: aws-cdk-lib.aws_ec2.IVpc
  • 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.

vpcSubnetsOptional 
public readonly vpcSubnets: SubnetSelection;
  • Type: aws-cdk-lib.aws_ec2.SubnetSelection
  • Default: the Vpc default strategy if not specified

Where to place the network interfaces within the VPC.

Only used if 'vpc' is supplied. Note: internet access for Lambdas requires a NAT gateway, so picking Public subnets is not allowed.
