Description

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 You can't modify the configuration of a published version, only the unpublished version.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.

Parameters

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

A description of the function.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-Environment_IsVariablesSet <Boolean>
This property is set to true if the property is set; false otherwise. This property can be used to determine if the related property was returned by a service response or if the related property should be sent to the service during a service call.
Required?False
Position?Named

-Environment_Variable <Hashtable>
Environment variable key-value pairs.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)

Position?Named
Accept pipeline input?True (ByPropertyName)
-FunctionName <String>
Amazon.Lambda.Model.UpdateFunctionConfigurationRequest.FunctionName
Required?True
Position?1
Accept pipeline input?True (ByValue, ByPropertyName)
-Handler <String>
The name of the method within your code that Lambda calls to execute your function. The format includes the file name. It can also include namespaces and other qualifiers, depending on the runtime. For more information, see Programming Model.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-IsLayersSet <Boolean>
This property is set to true if the property is set; false otherwise. This property can be used to determine if the related property was returned by a service response or if the related property should be sent to the service during a service call.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-KMSKeyArn <String>
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.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-Layer <String[]>
A list of function layers to add to the function's execution environment. Specify each layer by its ARN, including the version.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
AliasesLayers
-MemorySize <Int32>
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.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-PassThru <SwitchParameter>
Changes the cmdlet behavior to return the value passed to the FunctionName parameter. The -PassThru parameter is deprecated, use -Select '^FunctionName' instead. This parameter will be removed in a future version.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-RevisionId <String>
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.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-Role <String>
The Amazon Resource Name (ARN) of the function's execution role.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-Runtime <Runtime>
The identifier of the function's runtime.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-Select <String>
Use the -Select parameter to control the cmdlet output. The default value is '*'. Specifying -Select '*' will result in the cmdlet returning the whole service response (Amazon.Lambda.Model.UpdateFunctionConfigurationResponse). Specifying the name of a property of type Amazon.Lambda.Model.UpdateFunctionConfigurationResponse will result in that property being returned. Specifying -Select '^ParameterName' will result in the cmdlet returning the selected cmdlet parameter value.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-Timeout <Int32>
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.
Required?False
Position?Named

Common Credential and Region Parameters

-AccessKey <String>
The AWS access key for the user account. This can be a temporary access key if the corresponding session token is supplied to the -SessionToken parameter.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
AliasesAK
-Credential <AWSCredentials>
An AWSCredentials object instance containing access and secret key information, and optionally a token for session-based credentials.
Required?False
Position?Named
Accept pipeline input?True (ByValue, ByPropertyName)
-EndpointUrl <String>
The endpoint to make the call against.Note: This parameter is primarily for internal AWS use and is not required/should not be specified for normal usage. The cmdlets normally determine which endpoint to call based on the region specified to the -Region parameter or set as default in the shell (via Set-DefaultAWSRegion). Only specify this parameter if you must direct the call to a specific custom endpoint.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-NetworkCredential <PSCredential>
Used with SAML-based authentication when ProfileName references a SAML role profile. Contains the network credentials to be supplied during authentication with the configured identity provider's endpoint. This parameter is not required if the user's default network identity can or should be used during authentication.
Required?False
Position?Named
Accept pipeline input?True (ByValue, ByPropertyName)
-ProfileLocation <String>
Used to specify the name and location of the ini-format credential file (shared with the AWS CLI and other AWS SDKs)If this optional parameter is omitted this cmdlet will search the encrypted credential file used by the AWS SDK for .NET and AWS Toolkit for Visual Studio first. If the profile is not found then the cmdlet will search in the ini-format credential file at the default location: (user's home directory)\.aws\credentials.If this parameter is specified then this cmdlet will only search the ini-format credential file at the location given.As the current folder can vary in a shell or during script execution it is advised that you use specify a fully qualified path instead of a relative path.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
AliasesAWSProfilesLocation, ProfilesLocation
-ProfileName <String>
The user-defined name of an AWS credentials or SAML-based role profile containing credential information. The profile is expected to be found in the secure credential file shared with the AWS SDK for .NET and AWS Toolkit for Visual Studio. You can also specify the name of a profile stored in the .ini-format credential file used with the AWS CLI and other AWS SDKs.

Accept pipeline input?True (ByPropertyName)
