lambda_create_function: Creates a Lambda function

Description

Creates a Lambda function. To create a function, you need a deployment package and an execution role. The deployment package contains your function code. The execution role grants the function permission to use AWS services, such as Amazon CloudWatch Logs for log streaming and AWS X-Ray for request tracing.

Usage

lambda_create_function(FunctionName, Runtime, Role, Handler, Code,
  Description, Timeout, MemorySize, Publish, VpcConfig, DeadLetterConfig,
  Environment, KMSKeyArn, TracingConfig, Tags, Layers)

Arguments

FunctionName

[required] The name of the Lambda function.

Name formats

  • Function name - my-function.

  • Function ARN - arn:aws:lambda:us-west-2:123456789012:function:my-function.

  • Partial ARN - 123456789012:function:my-function.

The length constraint applies only to the full ARN. If you specify only the function name, it is limited to 64 characters in length.

Runtime

[required] The identifier of the function's runtime.

Role

[required] The Amazon Resource Name (ARN) of the function's execution role.

Handler

[required] 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 Programming Model.

Code

[required] The code for the function.

Description

A description of the function.

Timeout

The amount of time that Lambda allows a function to run before stopping it. The default is 3 seconds. The maximum allowed value is 900 seconds.

MemorySize

The amount of memory that your function has access to. Increasing the function's memory also increases its CPU allocation. The default value is 128 MB. The value must be a multiple of 64 MB.

Publish

Set to true to publish the first version of the function during creation.

VpcConfig

For network connectivity to AWS resources in a VPC, specify a list of security groups and subnets in the VPC. When you connect a function to a VPC, it can only access resources and the internet through that VPC. For more information, see VPC Settings.

DeadLetterConfig

A dead letter queue configuration that specifies the queue or topic where Lambda sends asynchronous events when they fail processing. For more information, see Dead Letter Queues.

Environment

Environment variables that are accessible from function code during execution.

KMSKeyArn

The ARN of the AWS Key Management Service (AWS KMS) key that's used to encrypt your function's environment variables. If it's not provided, AWS Lambda uses a default service key.

TracingConfig

Set Mode to Active to sample and trace a subset of incoming requests with AWS X-Ray.

Tags

A list of tags to apply to the function.

Layers

A list of function layers to add to the function's execution environment. Specify each layer by its ARN, including the version.

Details

A function has an unpublished version, and can have published versions and aliases. The unpublished version changes when you update your function's code and configuration. A published version is a snapshot of your function code and configuration that can't be changed. An alias is a named resource that maps to a version, and can be changed to map to a different version. Use the Publish parameter to create version 1 of your function from its initial configuration.

The other parameters let you configure version-specific and function-level settings. You can modify version-specific settings later with UpdateFunctionConfiguration. Function-level settings apply to both the unpublished and published versions of the function, and include tags (TagResource) and per-function concurrency limits (PutFunctionConcurrency).

If another account or an AWS service invokes your function, use AddPermission to grant permission by creating a resource-based IAM policy. You can grant permissions at the function level, on a version, or on an alias.

To invoke your function directly, use Invoke. To invoke your function in response to events in other AWS services, create an event source mapping (CreateEventSourceMapping), or configure a function trigger in the other service. For more information, see Invoking Functions.
