2016/02/11 - AWS Lambda - 8 updated api methods
{'VpcConfig': {'SecurityGroupIds': ['string'], 'SubnetIds': ['string']}}
Response {'VpcConfig': {'SecurityGroupIds': ['string'],
'SubnetIds': ['string'],
'VpcId': 'string'}}
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.

string
[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 APIs, such as Invoke .
string
[REQUIRED]
The runtime environment for the Lambda function you are uploading.
string
[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 .
string
[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) .
dict
[REQUIRED]
The code for the Lambda function.
ZipFile (bytes) --
A zip file containing your deployment package. If you are using the API directly, 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, go to 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.
string
A short, user-defined function description. Lambda does not use this value. Assign a meaningful description as you see fit.
integer
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.
integer
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.
boolean
This boolean parameter can be used to request AWS Lambda to create the Lambda function and publish a version as an atomic operation.
dict
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.

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.
Request Syntax
client.get_function(
FunctionName='string',

)
string
[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 character in length.
string
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.

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