update_function_configuration¶

Configuration for the capacity provider that manages compute resources for Lambda functions.

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.

A description of the function.

Configuration settings for durable functions, including execution timeout, retention period for execution history, and an optional ARN of the Key Management Service (KMS) customer managed key that is used to encrypt your durable execution's payload data, including input, output, and error payloads.

Environment variables that are accessible from function code during execution.

The size of the function's /tmp directory in MB. The default value is 512, but can be any whole number between 512 and 10,240 MB. For more information, see Configuring ephemeral storage (console).

Connection settings for an Amazon EFS file system or an Amazon S3 Files file system.

The name or ARN 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.

The name of the method within your code that Lambda calls to run your function. Handler is required if the deployment package is a .zip file archive. The format includes the file name. It can also include namespaces and other qualifiers, depending on the runtime. For more information, see Lambda programming model.

Container image configuration values that override the values in the container image Docker file.

The ARN of the Key Management Service (KMS) customer managed key that's used to encrypt the following resources:

• The function's environment variables.

• The function's Lambda SnapStart snapshots.

• When used with SourceKMSKeyArn, the unzipped version of the .zip deployment package that's used for function invocations. For more information, see Specifying a customer managed key for Lambda.

• The optimized version of the container image that's used for function invocations. Note that this is not the same key that's used to protect your container image in the Amazon Elastic Container Registry (Amazon ECR). For more information, see Function lifecycle.

If you don't provide a customer managed key, Lambda uses an Amazon Web Services owned key or an Amazon Web Services managed key.

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

The function's Amazon CloudWatch Logs configuration settings.

The amount of memory available to the function at runtime. Increasing the function memory also increases its CPU allocation. The default value is 128 MB. The value can be any multiple of 1 MB.

Update the function only 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.

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

The identifier of the function's runtime. Runtime is required if the deployment package is a .zip file archive. Specifying a runtime results in an error if you're deploying a function using a container image.

The following list includes deprecated runtimes. Lambda blocks creating new functions and updating existing functions shortly after each runtime is deprecated. For more information, see Runtime use after deprecation.

For a list of all currently supported runtimes, see Supported runtimes.

The function's SnapStart setting.

The amount of time (in seconds) that Lambda allows a function to run before stopping it. The default is 3 seconds. The maximum allowed value is 900 seconds. For more information, see Lambda execution environment.

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

For network connectivity to Amazon Web Services 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 access resources and the internet only through that VPC. For more information, see Configuring a Lambda function to access resources in a VPC.

The instruction set architecture that the function supports. Architecture is a string array with one of the valid values. The default architecture value is x86_64.

Configuration for the capacity provider that manages compute resources for Lambda functions.

The SHA256 hash of the function's deployment package.

The size of the function's deployment package, in bytes.

The SHA256 hash of the function configuration.

The function's dead letter queue.

The function's description.

The function's durable execution configuration settings, if the function is configured for durability.

The function's environment variables. Omitted from CloudTrail logs.

The size of the function's /tmp directory in MB. The default value is 512, but can be any whole number between 512 and 10,240 MB. For more information, see Configuring ephemeral storage (console).

Connection settings for an Amazon EFS file system or an Amazon S3 Files file system.

The function's Amazon Resource Name (ARN).

The name of the function.

The function that Lambda calls to begin running your function.

The function's image configuration values.

The ARN of the Key Management Service (KMS) customer managed key that's used to encrypt the following resources:

• The function's environment variables.

• The function's Lambda SnapStart snapshots.

• When used with SourceKMSKeyArn, the unzipped version of the .zip deployment package that's used for function invocations. For more information, see Specifying a customer managed key for Lambda.

• The optimized version of the container image that's used for function invocations. Note that this is not the same key that's used to protect your container image in the Amazon Elastic Container Registry (Amazon ECR). For more information, see Function lifecycle.

If you don't provide a customer managed key, Lambda uses an Amazon Web Services owned key or an Amazon Web Services managed key.

The date and time that the function was last updated, in ISO-8601 format (YYYY-MM-DDThhss.sTZD).

The status of the last update that was performed on the function. This is first set to Successful after function creation completes.

The reason for the last update that was performed on the function.

The reason code for the last update that was performed on the function.

The function's layers.

The function's Amazon CloudWatch Logs configuration settings.

For Lambda@Edge functions, the ARN of the main function.

The amount of memory available to the function at runtime.

The type of deployment package. Set to Image for container image and set Zip for .zip file archive.

The latest updated revision of the function or alias.

The function's execution role.

The identifier of the function's runtime. Runtime is required if the deployment package is a .zip file archive. Specifying a runtime results in an error if you're deploying a function using a container image.

The following list includes deprecated runtimes. Lambda blocks creating new functions and updating existing functions shortly after each runtime is deprecated. For more information, see Runtime use after deprecation.

For a list of all currently supported runtimes, see Supported runtimes.

The ARN of the runtime and any errors that occured.

The ARN of the signing job.

The ARN of the signing profile version.

Set ApplyOn to PublishedVersions to create a snapshot of the initialized execution environment when you publish a function version. For more information, see Improving startup performance with Lambda SnapStart.

The current state of the function. When the state is Inactive, you can reactivate the function by invoking it.

The reason for the function's current state.

The reason code for the function's current state. When the code is Creating, you can't invoke or modify the function.

The function's tenant isolation configuration settings. Determines whether the Lambda function runs on a shared or dedicated infrastructure per unique tenant.

The amount of time in seconds that Lambda allows a function to run before stopping it.

The function's X-Ray tracing configuration.

The version of the Lambda function.

The function's networking configuration.
