CreateFunction (updated)

Changes (both)

{'Runtime': {'dotnetcore3.1'}}

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.

When you create a function, Lambda provisions an instance of the function and its supporting resources. If your function connects to a VPC, this process can take a minute or so. During this time, you can't invoke or modify the function. The State , StateReason , and StateReasonCode fields in the response from GetFunctionConfiguration indicate when the function is ready to invoke. For more information, see Function States .

A function has an unpublished version, and can have published versions and aliases. The unpublished version changes when you update your function's code and configuration.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 Function-level settings apply to both the unpublished and published versions of the function, and include tags ( TagResource ) and per-function concurrency limits ( PutFunctionConcurrency ).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 .

PublishVersion (updated)

Link ¶
Changes (response)

{'Runtime': {'dotnetcore3.1'}}

Creates a version from the current code and configuration of a function. Use versions to create a snapshot of your function code and configuration that doesn't change.

AWS Lambda doesn't publish a version if the function's configuration and code haven't changed since the last version. Use UpdateFunctionCode or UpdateFunctionConfiguration to update the function before publishing a version.

Clients can invoke versions directly or with an alias. To create an alias, use CreateAlias .

type CodeSha256

string

param CodeSha256

Only publish a version if the hash value matches the value that's specified. Use this option to avoid publishing a version if the function code has changed since you last updated it. You can get the hash for the version that you uploaded from the output of UpdateFunctionCode .

type Description

UpdateFunctionConfiguration (updated)

Link ¶
Changes (both)

{'Runtime': {'dotnetcore3.1'}}

Modify the version-specific settings of a Lambda function.

When you update a function, Lambda provisions an instance of the function and its supporting resources. If your function connects to a VPC, this process can take a minute. During this time, you can't modify the function, but you can still invoke it. The LastUpdateStatus , LastUpdateStatusReason , and LastUpdateStatusReasonCode fields in the response from GetFunctionConfiguration indicate when the update is complete and the function is processing events with the new configuration. For more information, see Function States .

These settings can vary between versions of a function and are locked when you publish a version. You can't modify the configuration of a published version, only the unpublished version.

To configure function concurrency, use PutFunctionConcurrency . To grant invoke permissions to an account or AWS service, use AddPermission .

type FunctionName

string

param 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.

type Role

string

param Role

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

type Handler

string

param Handler

type Description

string

param Description

A description of the function.

type Timeout

integer

param 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.

type MemorySize

integer

param 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.

type VpcConfig

dict

param VpcConfig

SubnetIds (list) --

A list of VPC subnet IDs.
- (string) --
SecurityGroupIds (list) --

Variables (dict) --

Environment variable key-value pairs.
- (string) --
  - (string) --

type Runtime

string

param Runtime

The identifier of the function's runtime .

type DeadLetterConfig

dict

param 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 .

TargetArn (string) --

The Amazon Resource Name (ARN) of an Amazon SQS queue or Amazon SNS topic.

type KMSKeyArn

string

param 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.

type TracingConfig

dict

param TracingConfig

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

Mode (string) --

The tracing mode.

type RevisionId

string

param RevisionId

Only update the function if the revision ID matches the ID that's specified. Use this option to avoid modifying a function that has changed since you last read it.

type Layers

list

param Layers

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