Operations

AddLayerVersionPermission

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

Adds permissions to the resource-based policy of a version of anLambda 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, callRemoveLayerVersionPermission with the statement ID that you specified when you added it.

Examples

Example 1: To add permissions to a layer version

The following example grants permission for the account 223456789012 to use version 1 of a layer named my-layer.

$result = $client->addLayerVersionPermission([    'Action' => 'lambda:GetLayerVersion',    'LayerName' => 'my-layer',    'Principal' => '223456789012',    'StatementId' => 'xaccount',    'VersionNumber' => 1,]);

Result syntax:

[    'RevisionId' => '35d87451-f796-4a3f-a618-95a3671b0a0c',    'Statement' => '{"Sid":"xaccount","Effect":"Allow","Principal":{"AWS":"arn:aws:iam::223456789012:root"},"Action":"lambda:GetLayerVersion","Resource":"arn:aws:lambda:us-east-2:123456789012:layer:my-layer:1"}',]

AddPermission

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

Grants aprincipal 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 thePrincipal. To grant permission to an organization defined in Organizations, specify the organization ID as thePrincipalOrgID. For Amazon Web Services services, the principal is a domain-style identifier that the service defines, such ass3.amazonaws.com orsns.amazonaws.com. For Amazon Web Services services, you can also specify the ARN of the associated resource as theSourceArn. 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 operation adds a statement to a resource-based permissions policy for the function. For more information about function policies, seeUsing resource-based policies for Lambda.

Parameter Syntax

$result = $client->addPermission([    'Action' => '<string>', // REQUIRED    'EventSourceToken' => '<string>',    'FunctionName' => '<string>', // REQUIRED    'FunctionUrlAuthType' => 'NONE|AWS_IAM',    'Principal' => '<string>', // REQUIRED    'PrincipalOrgID' => '<string>',    'Qualifier' => '<string>',    'RevisionId' => '<string>',    'SourceAccount' => '<string>',    'SourceArn' => '<string>',    'StatementId' => '<string>', // REQUIRED]);

$result = $client->createAlias([/* ... */]);$promise = $client->createAliasAsync([/* ... */]);

Creates analias for a Lambda function version. Use aliases to provide clients with a function identifier that you can update to invoke a different version.

CreateEventSourceMapping

$result = $client->createEventSourceMapping([/* ... */]);$promise = $client->createEventSourceMappingAsync([/* ... */]);

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

For details about how to configure different event sources, see the following topics.

• Amazon DynamoDB Streams

• Amazon Kinesis

• Amazon SQS

• Amazon MQ and RabbitMQ

• Amazon MSK

• Apache Kafka

• Amazon DocumentDB

The following error handling options are available only for DynamoDB and Kinesis event sources:

• BisectBatchOnFunctionError – If the function returns an error, split the batch in two and retry.

• 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.

For stream sources (DynamoDB, Kinesis, Amazon MSK, and self-managed Apache Kafka), the following option is also available:

• OnFailure – Send discarded records to an Amazon SQS queue, Amazon SNS topic, or Amazon S3 bucket. For more information, seeAdding a destination.

For information about which configuration parameters apply to each event source, see the following topics.

Example 1: To create a mapping between an event source and an AWS Lambda function

The following example creates a mapping between an SQS queue and the my-function Lambda function.

$result = $client->createEventSourceMapping([    'BatchSize' => 5,    'EventSourceArn' => 'arn:aws:sqs:us-west-2:123456789012:my-queue',    'FunctionName' => 'my-function',]);

CreateFunction

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

Creates a Lambda function. To create a function, you need adeployment package and anexecution 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.

If the deployment package is acontainer image, then you set the package type toImage. 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.

If the deployment package is a.zip file archive, then you set the package type toZip. 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 orarm64). If you do not specify the architecture, then the default value isx86-64.

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. TheState,StateReason, andStateReasonCode fields in the response fromGetFunctionConfiguration indicate when the function is ready to invoke. For more information, seeLambda 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 thePublish parameter to create version1 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 withUpdateFunctionConfiguration. 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 withUpdateFunctionCode, Lambda checks that the code package has a valid signature from a trusted publisher. The code-signing configuration includes set of signing profiles, which define the trusted publishers for this function.

If another Amazon Web Services account or an Amazon Web Services service invokes your function, useAddPermission to grant permission by creating a resource-based Identity and Access Management (IAM) policy. You can grant permissions at the function level, on a version, or on an alias.

To invoke your function directly, useInvoke. 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, seeInvoking Lambda functions.
