      Returns:
      this
    • loggingFormat

      @Stability(Stable) public FunctionOptions.Builder loggingFormat(LoggingFormat loggingFormat)
      Parameters:
      loggingFormat - Sets the loggingFormat for the function.
      Returns:
      this
    • logGroup

      @Stability(Stable) public FunctionOptions.Builder logGroup(ILogGroup logGroup)
      Parameters:
      logGroup - The log group the function sends logs to. By default, Lambda functions send logs to an automatically created default log group named /aws/lambda/. 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.

      Returns:
      this
    • logRetention

      @Stability(Stable) public FunctionOptions.Builder logRetention(RetentionDays logRetention)
      Parameters:
      logRetention - 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 software.amazon.awscdk.services.logs.*;
                           
                           LogGroup myLogGroup;
                           
                           myLogGroup.getLogGroupName();
                           
      Returns:
      this
    • logRetentionRetryOptions

      @Stability(Stable) public FunctionOptions.Builder logRetentionRetryOptions(LogRetentionRetryOptions logRetentionRetryOptions)
      Parameters:
      logRetentionRetryOptions - 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.

      Returns:
      this
    • logRetentionRole

      @Stability(Stable) public FunctionOptions.Builder logRetentionRole(IRole logRetentionRole)
      Parameters:
      logRetentionRole - 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.
      Returns:
      this
    • memorySize

      @Stability(Stable) public FunctionOptions.Builder memorySize(Number memorySize)
      Parameters:
      memorySize - 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.
      Returns:
      this
    • paramsAndSecrets

      @Stability(Stable) public FunctionOptions.Builder paramsAndSecrets(ParamsAndSecretsLayerVersion paramsAndSecrets)

      @Stability(Stable) public FunctionOptions.Builder role(IRole role)
      Sets the value of FunctionOptions.getRole()
      Parameters:
      role - 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".

      Returns:
      this

    • timeout

      @Stability(Stable) public FunctionOptions.Builder timeout(Duration timeout)
      Parameters:
      timeout - 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.

      Sets the value of FunctionOptions.getVpc()
      Parameters:
      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.
      Returns:
      this

      @Stability(Stable) public FunctionOptions.Builder vpcSubnets(SubnetSelection vpcSubnets)
      Parameters:
      vpcSubnets - 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).
