If you provide a Role, you must add the relevant AWS managed policies yourself. The relevant managed policies are âservice-role/AWSLambdaBasicExecutionRoleâ and âservice-role/AWSLambdaVPCAccessExecutionRoleâ. Default: - A unique role will be generated for this lambda function. Both supplied and generated roles can always be changed by calling addToRolePolicy.
security_group (Optional[ISecurityGroup]) â (deprecated) What security group to associate with the Lambdaâs network interfaces. This property is being deprecated, consider using securityGroups instead. Only used if âvpcâ is supplied. Use securityGroups property instead.

Instead, use this.currentVersion to obtain a reference to a version resource that gets automatically recreated when the function configuration (or code) changes.
deprecated
Apply the given removal policy to this resource.
The Removal Policy controls what happens to this resource when it stops being managed by CloudFormation, either because youâve removed it from the CDK application or because youâve made a change that requires the resource to be replaced.
The resource can be deleted (RemovalPolicy.DESTROY), or left in your AWS account for data recovery and cleanup later (RemovalPolicy.RETAIN).
policy (RemovalPolicy)

Attributes
The architecture of this Lambda Function (this is an optional attribute and defaults to X86_64).
Access the Connections object.
Will fail if not a VPC-enabled Lambda Function
Returns a lambda.Version which represents the current version of this Lambda function. A new version will be created every time the functionâs configuration changes.
You can specify options for this version using the currentVersionOptions prop when initializing the lambda.Function.
The DLQ (as queue) associated with this Lambda Function (this is an optional attribute).
The DLQ (as topic) associated with this Lambda Function (this is an optional attribute).
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.
ARN of this function.
Name of this function.
The principal this Lambda Function is running as.
Whether or not this Lambda function was bound to a VPC.
If this is is false, trying to access the connections object will fail.
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.
The LogGroup where the Lambda functionâs 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 doesnât 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.
The construct tree node associated with this construct.
The construct node where permissions are attached.
The ARN(s) to put into the resource field of the generated IAM policy for grantInvoke().
Execution role associated with this function.
The runtime configured for this lambda.
The stack in which this resource is defined.
The timeout configured for this lambda.
Static Methods
Record whether specific properties in the AWS::Lambda::Function resource should also be associated to the Version resource.
See âcurrentVersionâ section in the module README for more details.
property_name (str) â The property to classify.
locked (bool) â whether the property should be associated to the version or not.

Import a lambda function into the CDK using its ARN.
Creates a Lambda function object which represents a function not defined within this stack.

architecture (Optional[Architecture]) â The architecture of this Lambda Function (this is an optional attribute and defaults to X86_64). Default: - Architecture.X86_64
role (Optional[IRole]) â The IAM execution role associated with this function. If the role is not specified, any role-related operations will no-op.
same_environment (Optional[bool]) â Setting this property informs the CDK that the imported function is in the same environment as the stack. This affects certain behaviours such as, whether this functionâs permission can be modified. When not configured, the CDK attempts to auto-determine this. For environment agnostic stacks, i.e., stacks where the account is not specified with the env property, this is determined to be false. Set this to property ONLY IF the imported function is in the same account as the stack itâs imported in. Default: - depends: true, if the Stack is configured with an explicit env (account and region) and the account is the same as this function. For environment-agnostic stacks this will default to false.
security_group (Optional[ISecurityGroup]) â The security group of this Lambda, if in a VPC. This needs to be given in order to support allowing connections to this Lambda.
security_group_id (Optional[str]) â (deprecated) Id of the security group of this Lambda, if in a VPC. This needs to be given in order to support allowing connections to this Lambda.
skip_permissions (Optional[bool]) â Setting this property informs the CDK that the imported function ALREADY HAS the necessary permissions for what you are trying to do. When not configured, the CDK attempts to auto-determine whether or not additional permissions are necessary on the function when grant APIs are used. If the CDK tried to add permissions on an imported lambda, it will fail. Set this property ONLY IF you are committing to manage the imported functionâs permissions outside of CDK. You are acknowledging that your CDK code alone will have insufficient permissions to access the imported function. Default: false
Import a lambda function into the CDK using its name.
Return whether the given object is a Construct.
x (Any)
bool
Check whether the given construct is a Resource.
construct (IConstruct)
bool
Return the given named metric for this Lambda.
