AWS SDK for PHP 3.x

Service ID: lambda

Version: 2015-03-31

This page describes the parameters and results for the operations of the AWS Lambda (2015-03-31), and shows how to use the Aws\Lambda\LambdaClient object to call the described operations. This documentation is specific to the 2015-03-31 API version of the service.

Operation Summary

Each of the following operations can be created from a client using $client->getCommand('CommandName'), where "CommandName" is the name of one of the following operations. Note: a command is a value that encapsulates an operation and the parameters used to create an HTTP request.

You can also create and send a command immediately using the magic methods available on a client object: $client->commandName(/* parameters */). You can send the command asynchronously (returning a promise) by appending the word "Async" to the operation name: $client->commandNameAsync(/* parameters */).

Paginators

Paginators handle automatically iterating over paginated API results. Paginators are associated with specific API operations, and they accept the parameters that the corresponding API operation accepts. You can get a paginator from a client class using getPaginator($paginatorName, $operationParameters). This client supports the following paginators:

ListAliases
ListCodeSigningConfigs
ListEventSourceMappings
ListFunctionEventInvokeConfigs
ListFunctions
ListFunctionsByCodeSigningConfig
ListLayerVersions
ListLayers
ListProvisionedConcurrencyConfigs
ListVersionsByFunction

Waiters

Waiters allow you to poll a resource until it enters into a desired state. A waiter has a name used to describe what it does, and is associated with an API operation. When creating a waiter, you can provide the API operation parameters associated with the corresponding operation. Waiters can be accessed using the getWaiter($waiterName, $operationParameters) method of a client object. This client supports the following waiters:

Waiter name	API Operation	Delay	Max Attempts
FunctionExists	GetFunction	1	20
FunctionActive	GetFunctionConfiguration	5	60
FunctionUpdated	GetFunctionConfiguration	5	60

Operations

AddLayerVersionPermission

$result = $client->addLayerVersionPermission([/* ... */]);
$promise = $client->addLayerVersionPermissionAsync([/* ... */]);

Adds permissions to the resource-based policy of a version of an Lambda layer. 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.

Errors

ServiceException:
The Lambda service encountered an internal error.
ResourceNotFoundException:
The resource specified in the request does not exist.
ResourceConflictException:
The resource already exists, or another operation is in progress.
TooManyRequestsException:
The request throughput limit was exceeded.
InvalidParameterValueException:
One of the parameters in the request is invalid.

AddPermission

$result = $client->addPermission([/* ... */]);
$promise = $client->addPermissionAsync([/* ... */]);

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. Note: Lambda does not support adding policies to version $LATEST.

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.

Parameter Syntax

$result = $client->addPermission([
    'Action' => '<string>', // REQUIRED
    'EventSourceToken' => '<string>',

CreateFunction

$result = $client->createFunction([/* ... */]);
$promise = $client->createFunctionAsync([/* ... */]);

Creates a Lambda function. To create a function, you need a deployment package and an 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. 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. For a .zip file archive, the code property specifies the location of the .zip file. You must also specify the handler and runtime properties. The code in the deployment package must be compatible with the target instruction set architecture of the function (x86-64 or arm64). If you do not specify the architecture, the default value is x86-64.

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).

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.

Invoke

$result = $client->invoke([/* ... */]);
$promise = $client->invokeAsync([/* ... */]);

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, 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 and trace.

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.

For asynchronous invocation, 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.

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, 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 action.

Parameter Syntax

$result = $client->invoke([
    'ClientContext' => '<string>',
    'FunctionName' => '<string>', // REQUIRED
    'InvocationType' => 'Event|RequestResponse|DryRun',

DryRun - Validate parameter values and verify that the user or role has permission to invoke the function.

LogType

Type: string

Set to Tail to include the execution log in the response. Applies to synchronously invoked functions only.

Payload

Type: blob (string|resource|Psr\Http\Message\StreamInterface)

PublishVersion

$result = $client->publishVersion([/* ... */]);
$promise = $client->publishVersionAsync([/* ... */]);

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.

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.

PutFunctionConcurrency

$result = $client->putFunctionConcurrency([/* ... */]);
$promise = $client->putFunctionConcurrencyAsync([/* ... */]);

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.

PutFunctionEventInvokeConfig

$result = $client->putFunctionEventInvokeConfig([/* ... */]);
$promise = $client->putFunctionEventInvokeConfigAsync([/* ... */]);

Configures options for asynchronous invocation 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. 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.

UpdateFunctionCode

$result = $client->updateFunctionCode([/* ... */]);
$promise = $client->updateFunctionCodeAsync([/* ... */]);

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.

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.

UpdateFunctionConfiguration

$result = $client->updateFunctionConfiguration([/* ... */]);
$promise = $client->updateFunctionConfigurationAsync([/* ... */]);

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 Amazon Web Services service, use AddPermission.
