METHODS

AddLayerVersionPermission

Action => Str
LayerName => Str
Principal => Str
StatementId => Str
VersionNumber => Int
[OrganizationId => Str]
[RevisionId => Str]

Each argument is described in detail in: Paws::Lambda::AddLayerVersionPermission

Returns: a Paws::Lambda::AddLayerVersionPermissionResponse instance

Adds permissions to the resource-based policy of a version of an Lambda layer (https://docs.aws.amazon.com/lambda/latest/dg/configuration-layers.html). Use this action to grant layer usage permission to other accounts. You can grant permission to a single account, all accounts in an organization, or all Amazon Web Services accounts.

To revoke permission, call RemoveLayerVersionPermission with the statement ID that you specified when you added it.

AddPermission

Action => Str
FunctionName => Str
Principal => Str
StatementId => Str
[EventSourceToken => Str]
[Qualifier => Str]
[RevisionId => Str]
[SourceAccount => Str]
[SourceArn => Str]

Each argument is described in detail in: Paws::Lambda::AddPermission

Returns: a Paws::Lambda::AddPermissionResponse instance

Grants an Amazon Web Services service or another account permission to use a function. You can apply the policy at the function level, or specify a qualifier to restrict access to a single version or alias. If you use a qualifier, the invoker must use the full Amazon Resource Name (ARN) of that version or alias to invoke the function.

To grant permission to another account, specify the account ID as the Principal. For Amazon Web Services services, the principal is a domain-style identifier defined by the service, like s3.amazonaws.com or sns.amazonaws.com. For Amazon Web Services services, you can also specify the ARN of the associated resource as the SourceArn. If you grant permission to a service principal without specifying the source, other accounts could potentially configure resources in their account to invoke your Lambda function.

This action adds a statement to a resource-based permissions policy for the function. For more information about function policies, see Lambda Function Policies (https://docs.aws.amazon.com/lambda/latest/dg/access-control-resource-based.html).

CreateAlias

FunctionName => Str
FunctionVersion => Str
Name => Str
[Description => Str]
[RoutingConfig => Paws::Lambda::AliasRoutingConfiguration]

Each argument is described in detail in: Paws::Lambda::CreateAlias

Returns: a Paws::Lambda::AliasConfiguration instance

Creates an alias (https://docs.aws.amazon.com/lambda/latest/dg/versioning-aliases.html) for a Lambda function version. Use aliases to provide clients with a function identifier that you can update to invoke a different version.

You can also map an alias to split invocation requests between two versions. Use the RoutingConfig parameter to specify a second version and the percentage of invocation requests that it receives.

CreateCodeSigningConfig

AllowedPublishers => Paws::Lambda::AllowedPublishers
[CodeSigningPolicies => Paws::Lambda::CodeSigningPolicies]
[Description => Str]

Each argument is described in detail in: Paws::Lambda::CreateCodeSigningConfig

Returns: a Paws::Lambda::CreateCodeSigningConfigResponse instance

Creates a code signing configuration. A code signing configuration (https://docs.aws.amazon.com/lambda/latest/dg/configuration-trustedcode.html) defines a list of allowed signing profiles and defines the code-signing validation policy (action to be taken if deployment validation checks fail).

[TumblingWindowInSeconds => Int]

Each argument is described in detail in: Paws::Lambda::CreateEventSourceMapping

Returns: a Paws::Lambda::EventSourceMappingConfiguration instance

Creates a mapping between an event source and an Lambda function. Lambda reads items from the event source and triggers the function.

For details about each event source type, see the following topics. In particular, each of the topics describes the required and optional parameters for the specific event source.

Configuring a Dynamo DB stream as an event source (https://docs.aws.amazon.com/lambda/latest/dg/with-ddb.html#services-dynamodb-eventsourcemapping)
Configuring a Kinesis stream as an event source (https://docs.aws.amazon.com/lambda/latest/dg/with-kinesis.html#services-kinesis-eventsourcemapping)
Configuring an SQS queue as an event source (https://docs.aws.amazon.com/lambda/latest/dg/with-sqs.html#events-sqs-eventsource)
Configuring an MQ broker as an event source (https://docs.aws.amazon.com/lambda/latest/dg/with-mq.html#services-mq-eventsourcemapping)
Configuring MSK as an event source (https://docs.aws.amazon.com/lambda/latest/dg/with-msk.html)
Configuring Self-Managed Apache Kafka as an event source (https://docs.aws.amazon.com/lambda/latest/dg/kafka-smaa.html)

The following error handling options are only available for stream sources (DynamoDB and Kinesis):

BisectBatchOnFunctionError - If the function returns an error, split the batch in two and retry.
DestinationConfig - Send discarded records to an Amazon SQS queue or Amazon SNS topic.
MaximumRecordAgeInSeconds - Discard records older than the specified age. The default value is infinite (-1). When set to infinite (-1), failed records are retried until the record expires
MaximumRetryAttempts - Discard records after the specified number of retries. The default value is infinite (-1). When set to infinite (-1), failed records are retried until the record expires.
ParallelizationFactor - Process multiple batches from each shard concurrently.

[Timeout => Int]
[TracingConfig => Paws::Lambda::TracingConfig]
[VpcConfig => Paws::Lambda::VpcConfig]

Each argument is described in detail in: Paws::Lambda::CreateFunction

Returns: a Paws::Lambda::FunctionConfiguration instance

Creates a Lambda function. To create a function, you need a deployment package (https://docs.aws.amazon.com/lambda/latest/dg/gettingstarted-package.html) and an execution role (https://docs.aws.amazon.com/lambda/latest/dg/intro-permission-model.html#lambda-intro-execution-role). The deployment package is a .zip file archive or container image that contains your function code. The execution role grants the function permission to use Amazon Web Services services, such as Amazon CloudWatch Logs for log streaming and X-Ray for request tracing.

You set the package type to Image if the deployment package is a container image (https://docs.aws.amazon.com/lambda/latest/dg/lambda-images.html). For a container image, the code property must include the URI of a container image in the Amazon ECR registry. You do not need to specify the handler and runtime properties.

You set the package type to Zip if the deployment package is a .zip file archive (https://docs.aws.amazon.com/lambda/latest/dg/gettingstarted-package.html#gettingstarted-package-zip). For a .zip file archive, the code property specifies the location of the .zip file. You must also specify the handler and runtime properties.

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 (https://docs.aws.amazon.com/lambda/latest/dg/functions-states.html).

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).

You can use code signing if your deployment package is a .zip file archive. To enable code signing for this function, specify the ARN of a code-signing configuration. When a user attempts to deploy a code package with UpdateFunctionCode, Lambda checks that the code package has a valid signature from a trusted publisher. The code-signing configuration includes set set of signing profiles, which define the trusted publishers for this function.

If another account or an Amazon Web Services 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 Amazon Web Services services, create an event source mapping (CreateEventSourceMapping), or configure a function trigger in the other service. For more information, see Invoking Functions (https://docs.aws.amazon.com/lambda/latest/dg/lambda-invocation.html).

Retrieves the provisioned concurrency configuration for a function's alias or version.

Invoke

FunctionName => Str
[ClientContext => Str]
[InvocationType => Str]
[LogType => Str]
[Payload => Str]
[Qualifier => Str]

Each argument is described in detail in: Paws::Lambda::Invoke

Returns: a Paws::Lambda::InvocationResponse instance

Invokes a Lambda function. You can invoke a function synchronously (and wait for the response), or asynchronously. To invoke a function asynchronously, set InvocationType to Event.

For synchronous invocation (https://docs.aws.amazon.com/lambda/latest/dg/invocation-sync.html), details about the function response, including errors, are included in the response body and headers. For either invocation type, you can find more information in the execution log (https://docs.aws.amazon.com/lambda/latest/dg/monitoring-functions.html) and trace (https://docs.aws.amazon.com/lambda/latest/dg/lambda-x-ray.html).

When an error occurs, your function may be invoked multiple times. Retry behavior varies by error type, client, event source, and invocation type. For example, if you invoke a function asynchronously and it returns an error, Lambda executes the function up to two more times. For more information, see Retry Behavior (https://docs.aws.amazon.com/lambda/latest/dg/retries-on-errors.html).

For asynchronous invocation (https://docs.aws.amazon.com/lambda/latest/dg/invocation-async.html), Lambda adds events to a queue before sending them to your function. If your function does not have enough capacity to keep up with the queue, events may be lost. Occasionally, your function may receive the same event multiple times, even if no error occurs. To retain events that were not processed, configure your function with a dead-letter queue (https://docs.aws.amazon.com/lambda/latest/dg/invocation-async.html#dlq).

The status code in the API response doesn't reflect function errors. Error codes are reserved for errors that prevent your function from executing, such as permissions errors, limit errors (https://docs.aws.amazon.com/lambda/latest/dg/limits.html), or issues with your function's code and configuration. For example, Lambda returns TooManyRequestsException if executing the function would cause you to exceed a concurrency limit at either the account level (ConcurrentInvocationLimitExceeded) or function level (ReservedFunctionConcurrentInvocationLimitExceeded).

For functions with a long timeout, your client might be disconnected during synchronous invocation while it waits for a response. Configure your HTTP client, SDK, firewall, proxy, or operating system to allow for long connections with timeout or keep-alive settings.

This operation requires permission for the lambda:InvokeFunction (https://docs.aws.amazon.com/IAM/latest/UserGuide/list_awslambda.html) action.

Returns: a Paws::Lambda::PublishLayerVersionResponse instance

Creates an Lambda layer (https://docs.aws.amazon.com/lambda/latest/dg/configuration-layers.html) from a ZIP archive. Each time you call PublishLayerVersion with the same layer name, a new version is created.

Add layers to your function with CreateFunction or UpdateFunctionConfiguration.

PublishVersion

FunctionName => Str
[CodeSha256 => Str]
[Description => Str]
[RevisionId => Str]

Each argument is described in detail in: Paws::Lambda::PublishVersion

Returns: a Paws::Lambda::FunctionConfiguration instance

Creates a version (https://docs.aws.amazon.com/lambda/latest/dg/versioning-aliases.html) 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.

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.

PutFunctionCodeSigningConfig

CodeSigningConfigArn => Str
FunctionName => Str

Each argument is described in detail in: Paws::Lambda::PutFunctionCodeSigningConfig

Returns: a Paws::Lambda::PutFunctionCodeSigningConfigResponse instance

Update the code signing configuration for the function. Changes to the code signing configuration take effect the next time a user tries to deploy a code package to the function.

PutFunctionConcurrency

FunctionName => Str
ReservedConcurrentExecutions => Int

Each argument is described in detail in: Paws::Lambda::PutFunctionConcurrency

Returns: a Paws::Lambda::Concurrency instance

Sets the maximum number of simultaneous executions for a function, and reserves capacity for that concurrency level.

Concurrency settings apply to the function as a whole, including all published versions and the unpublished version. Reserving concurrency both ensures that your function has capacity to process the specified number of events simultaneously, and prevents it from scaling beyond that level. Use GetFunction to see the current setting for a function.

Use GetAccountSettings to see your Regional concurrency limit. You can reserve concurrency for as many functions as you like, as long as you leave at least 100 simultaneous executions unreserved for functions that aren't configured with a per-function limit. For more information, see Managing Concurrency (https://docs.aws.amazon.com/lambda/latest/dg/concurrent-executions.html).

PutFunctionEventInvokeConfig

FunctionName => Str
[DestinationConfig => Paws::Lambda::DestinationConfig]
[MaximumEventAgeInSeconds => Int]
[MaximumRetryAttempts => Int]
[Qualifier => Str]

Each argument is described in detail in: Paws::Lambda::PutFunctionEventInvokeConfig

Returns: a Paws::Lambda::FunctionEventInvokeConfig instance

Configures options for asynchronous invocation (https://docs.aws.amazon.com/lambda/latest/dg/invocation-async.html) on a function, version, or alias. If a configuration already exists for a function, version, or alias, this operation overwrites it. If you exclude any settings, they are removed. To set one option without affecting existing settings for other options, use UpdateFunctionEventInvokeConfig.

By default, Lambda retries an asynchronous invocation twice if the function returns an error. It retains events in a queue for up to six hours. When an event fails all processing attempts or stays in the asynchronous invocation queue for too long, Lambda discards it. To retain discarded events, configure a dead-letter queue with UpdateFunctionConfiguration.

To send an invocation record to a queue, topic, function, or event bus, specify a destination (https://docs.aws.amazon.com/lambda/latest/dg/invocation-async.html#invocation-async-destinations). You can configure separate destinations for successful invocations (on-success) and events that fail all processing attempts (on-failure). You can configure destinations in addition to or instead of a dead-letter queue.

[Description => Str]

Each argument is described in detail in: Paws::Lambda::UpdateCodeSigningConfig

Returns: a Paws::Lambda::UpdateCodeSigningConfigResponse instance

Update the code signing configuration. Changes to the code signing configuration take effect the next time a user tries to deploy a code package to the function.

Each argument is described in detail in: Paws::Lambda::UpdateEventSourceMapping

Returns: a Paws::Lambda::EventSourceMappingConfiguration instance

Updates an event source mapping. You can change the function that Lambda invokes, or pause invocation and resume later from the same location.

The following error handling options are only available for stream sources (DynamoDB and Kinesis):

BisectBatchOnFunctionError - If the function returns an error, split the batch in two and retry.
DestinationConfig - Send discarded records to an Amazon SQS queue or Amazon SNS topic.
MaximumRecordAgeInSeconds - Discard records older than the specified age. The default value is infinite (-1). When set to infinite (-1), failed records are retried until the record expires
MaximumRetryAttempts - Discard records after the specified number of retries. The default value is infinite (-1). When set to infinite (-1), failed records are retried until the record expires.
ParallelizationFactor - Process multiple batches from each shard concurrently.

Each argument is described in detail in: Paws::Lambda::UpdateFunctionCode

Returns: a Paws::Lambda::FunctionConfiguration instance

Updates a Lambda function's code. If code signing is enabled for the function, the code package must be signed by a trusted publisher. For more information, see Configuring code signing (https://docs.aws.amazon.com/lambda/latest/dg/configuration-trustedcode.html).

The function's code is locked when you publish a version. You can't modify the code of a published version, only the unpublished version.

For a function defined as a container image, Lambda resolves the image tag to an image digest. In Amazon ECR, if you update the image tag to a new image, Lambda does not automatically update the function.

Each argument is described in detail in: Paws::Lambda::UpdateFunctionConfiguration

Returns: a Paws::Lambda::FunctionConfiguration instance

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 (https://docs.aws.amazon.com/lambda/latest/dg/functions-states.html).

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 Amazon Web Services service, use AddPermission.

UpdateFunctionEventInvokeConfig

FunctionName => Str
[DestinationConfig => Paws::Lambda::DestinationConfig]
[MaximumEventAgeInSeconds => Int]

[Qualifier => Str]

Each argument is described in detail in: Paws::Lambda::UpdateFunctionEventInvokeConfig

Returns: a Paws::Lambda::FunctionEventInvokeConfig instance

Updates the configuration for asynchronous invocation for a function, version, or alias.

To configure options for asynchronous invocation, use PutFunctionEventInvokeConfig.
