AWS API Changes

2017/04/18 - AWS Lambda - 3 new 8 updated api methods

Changes You can use tags to group and filter your Lambda functions, making it easier to analyze them for billing allocation purposes. For more information, see Tagging Lambda Functions. You can now write or upgrade your Lambda functions using Python version 3.6. For more information, see Programming Model for Authoring Lambda Functions in Python. Note: Features will be rolled out in the US regions on 4/19.

CreateFunction (updated)

Link ¶
Changes (request, response)
Request

{'Runtime': ['python3.6'], 'Tags': {'string': 'string'}}

Response

{'Runtime': ['python3.6']}

Creates a new Lambda function. The function metadata is created from the request parameters, and the code for the function is provided by a .zip file in the request body. If the function name already exists, the operation will fail. Note that the function name is case-sensitive.

If you are using versioning, you can also publish a version of the Lambda function you are creating using the Publish parameter. For more information about versioning, see AWS Lambda Function Versioning and Aliases .

This operation requires permission for the lambda:CreateFunction action.

type FunctionName

string

param FunctionName

[REQUIRED]

The name you want to assign to the function you are uploading. The function names appear in the console and are returned in the ListFunctions API. Function names are used to specify functions to other AWS Lambda API operations, such as Invoke . Note that the length constraint applies only to the ARN. If you specify only the function name, it is limited to 64 characters in length.

type Runtime

string

param Runtime

[REQUIRED]

The runtime environment for the Lambda function you are uploading.

Note

You can no longer create functions using the v0.10.42 runtime version as of November, 2016. Existing functions will be supported until early 2017, but we recommend you migrate them to either nodejs6.10 or nodejs4.3 runtime version as soon as possible.

type Role

string

param Role

[REQUIRED]

The Amazon Resource Name (ARN) of the IAM role that Lambda assumes when it executes your function to access any other Amazon Web Services (AWS) resources. For more information, see AWS Lambda: How it Works .

type Handler

string

param Handler

[REQUIRED]

The function within your code that Lambda calls to begin execution. For Node.js, it is the module-name .*export* value in your function. For Java, it can be package.class-name::handler or package.class-name . For more information, see Lambda Function Handler (Java) .

type Code

dict

param Code

[REQUIRED]

The code for the Lambda function.

ZipFile (bytes) --

The contents of your zip file containing your deployment package. If you are using the web API directly, the contents of the zip file must be base64-encoded. If you are using the AWS SDKs or the AWS CLI, the SDKs or CLI will do the encoding for you. For more information about creating a .zip file, see Execution Permissions in the AWS Lambda Developer Guide .
S3Bucket (string) --

Amazon S3 bucket name where the .zip file containing your deployment package is stored. This bucket must reside in the same AWS region where you are creating the Lambda function.
S3Key (string) --

The Amazon S3 object (the deployment package) key name you want to upload.
S3ObjectVersion (string) --

The Amazon S3 object (the deployment package) version you want to upload.

type Description

string

param Description

A short, user-defined function description. Lambda does not use this value. Assign a meaningful description as you see fit.

type Timeout

integer

param Timeout

The function execution time at which Lambda should terminate the function. Because the execution time has cost implications, we recommend you set this value based on your expected execution time. The default is 3 seconds.

type MemorySize

integer

param MemorySize

The amount of memory, in MB, your Lambda function is given. Lambda uses this memory size to infer the amount of CPU and memory allocated to your function. Your function use-case determines your CPU and memory requirements. For example, a database operation might need less memory compared to an image processing function. The default value is 128 MB. The value must be a multiple of 64 MB.

type Publish

boolean

param Publish

This boolean parameter can be used to request AWS Lambda to create the Lambda function and publish a version as an atomic operation.

type VpcConfig

dict

param VpcConfig

If your Lambda function accesses resources in a VPC, you provide this parameter identifying the list of security group IDs and subnet IDs. These must belong to the same VPC. You must provide at least one security group and one subnet ID.

SubnetIds (list) --

A list of one or more subnet IDs in your VPC.
- (string) --
SecurityGroupIds (list) --

A list of one or more security groups IDs in your VPC.
- (string) --

type DeadLetterConfig

dict

param DeadLetterConfig

The parent object that contains the target Amazon Resource Name (ARN) of an Amazon SQS queue or Amazon SNS topic.

TargetArn (string) --

The Amazon Resource Name (ARN) of an Amazon SQS queue or Amazon SNS topic you specify as your Dead Letter Queue (DLQ).

type Environment

dict

param Environment

The parent object that contains your environment's configuration settings.

Variables (dict) --

The key-value pairs that represent your environment's configuration settings. The value you specify cannot contain a ",".
- (string) --
  - (string) --

type KMSKeyArn

string

param KMSKeyArn

The Amazon Resource Name (ARN) of the KMS key used to encrypt your function's environment variables. If not provided, AWS Lambda will use a default service key.

type Tags

dict

param Tags

The list of tags (key-value pairs) assigned to the new function.

GetFunction (updated)

Link ¶
Changes (response)

{'Configuration': {'Runtime': ['python3.6']}, 'Tags': {'string': 'string'}}

Returns the configuration information of the Lambda function and a presigned URL link to the .zip file you uploaded with CreateFunction so you can download the .zip file. Note that the URL is valid for up to 10 minutes. The configuration information is the same information you provided as parameters when uploading the function.

Using the optional Qualifier parameter, you can specify a specific function version for which you want this information. If you don't specify this parameter, the API uses unqualified function ARN which return information about the $LATEST version of the Lambda function. For more information, see AWS Lambda Function Versioning and Aliases .

This operation requires permission for the lambda:GetFunction action.

See also: AWS API Documentation

Request Syntax

client.get_function(
    FunctionName='string',
    Qualifier='string'
)

type FunctionName

string

param FunctionName

[REQUIRED]

The Lambda function name.

You can specify a function name (for example, Thumbnail ) or you can specify Amazon Resource Name (ARN) of the function (for example, arn:aws:lambda:us-west-2:account-id:function:ThumbNail ). AWS Lambda also allows you to specify a partial ARN (for example, account-id:Thumbnail ). Note that the length constraint applies only to the ARN. If you specify only the function name, it is limited to 64 characters in length.

type Qualifier

string

param Qualifier

Using this optional parameter to specify a function version or an alias name. If you specify function version, the API uses qualified function ARN for the request and returns information about the specific Lambda function version. If you specify an alias name, the API uses the alias ARN and returns information about the function version to which the alias points. If you don't provide this parameter, the API uses unqualified function ARN and returns information about the $LATEST version of the Lambda function.

type FunctionName

string

param FunctionName

[REQUIRED]

The name of the Lambda function.

type Role

string

param Role

The Amazon Resource Name (ARN) of the IAM role that Lambda will assume when it executes your function.

type Handler

string

param Handler

The function that Lambda calls to begin executing your function. For Node.js, it is the module-name.export value in your function.

type Description

string

param Description

A short user-defined function description. AWS Lambda does not use this value. Assign a meaningful description as you see fit.

type Timeout

integer

param Timeout

The function execution time at which AWS Lambda should terminate the function. Because the execution time has cost implications, we recommend you set this value based on your expected execution time. The default is 3 seconds.

type MemorySize

integer

param MemorySize

The amount of memory, in MB, your Lambda function is given. AWS Lambda uses this memory size to infer the amount of CPU allocated to your function. Your function use-case determines your CPU and memory requirements. For example, a database operation might need less memory compared to an image processing function. The default value is 128 MB. The value must be a multiple of 64 MB.

type VpcConfig

dict

param VpcConfig

SubnetIds (list) --

A list of one or more subnet IDs in your VPC.
- (string) --
SecurityGroupIds (list) --

A list of one or more security groups IDs in your VPC.
- (string) --

type Environment

dict

param Environment

The parent object that contains your environment's configuration settings.

Variables (dict) --

The key-value pairs that represent your environment's configuration settings. The value you specify cannot contain a ",".
- (string) --
  - (string) --

type Runtime

string

param Runtime

The runtime environment for the Lambda function.

To use the Python runtime v3.6, set the value to "python3.6". To use the Python runtime v2.7, set the value to "python2.7". To use the Node.js runtime v6.10, set the value to "nodejs6.10". To use the Node.js runtime v4.3, set the value to "nodejs4.3". To use the Python runtime v3.6, set the value to "python3.6". To use the Python runtime v2.7, set the value to "python2.7".

Note

You can no longer downgrade to the v0.10.42 runtime version. This version will no longer be supported as of early 2017.

type DeadLetterConfig

dict

param DeadLetterConfig

The parent object that contains the target Amazon Resource Name (ARN) of an Amazon SQS queue or Amazon SNS topic.

TargetArn (string) --

The Amazon Resource Name (ARN) of an Amazon SQS queue or Amazon SNS topic you specify as your Dead Letter Queue (DLQ).

type KMSKeyArn

string

param KMSKeyArn

The Amazon Resource Name (ARN) of the KMS key used to encrypt your function's environment variables. If you elect to use the AWS Lambda default service key, pass in an empty string ("") for this parameter.

rtype

dict

returns
