Synopsis

Invokes the DeleteFunction operation against Amazon Lambda.

Syntax

Remove-LMFunction
-FunctionName <String>
-Qualifier <String>
-PassThru <SwitchParameter>
-Force <SwitchParameter>

Description

Deletes the specified Lambda function code and configuration. If you are using the versioning feature and you don't specify a function version in your DeleteFunction request, AWS Lambda will delete the function, including all its versions, and any aliases pointing to the function versions. To delete a specific function version, you must provide the function version via the Qualifier parameter. For information about function versioning, see AWS Lambda Function Versioning and Aliases. When you delete a function the associated resource policy is also deleted. You will need to delete the event source mappings explicitly. This operation requires permission for the lambda:DeleteFunction action.

Parameters

-Force <SwitchParameter>
This parameter overrides confirmation prompts to force the cmdlet to continue its operation. This parameter should always be used with caution.
Required?False
Position?Named
Accept pipeline input?False
-FunctionName <String>
The Lambda function to delete. You can specify the function name (for example, Thumbnail) or you can specify Amazon Resource Name (ARN) of the function (for example, arn:aws:lambda:us-west-2:account-id:function:ThumbNail). If you are using versioning, you can also provide a qualified function ARN (ARN that is qualified with function version or alias name as suffix). AWS Lambda also allows you to specify only the function name with the account ID qualifier (for example, account-id:Thumbnail). Note that the length constraint applies only to the ARN. If you specify only the function name, it is limited to 64 characters in length.
Required?False
Position?1
Accept pipeline input?True (ByValue, ByPropertyName)
-PassThru <SwitchParameter>
Returns the value passed to the FunctionName parameter. By default, this cmdlet does not generate any output.
Required?False
Position?Named
Accept pipeline input?False
-Qualifier <String>
Using this optional parameter you can specify a function version (but not the $LATEST version) to direct AWS Lambda to delete a specific function version. If the function version has one or more aliases pointing to it, you will get an error because you cannot have aliases pointing to it. You can delete any function version but not the $LATEST, that is, you cannot specify $LATEST as the value of this parameter. The $LATEST version can be deleted only when you want to delete all the function versions and aliases.You can only specify a function version, not an alias name, using this parameter. You cannot delete a function version using its alias.If you don't specify this parameter, AWS Lambda will delete the function, including all of its versions and aliases.
Required?False
Position?Named
Accept pipeline input?False

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? False
-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? False
-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. Note that the encrypted credential file is not supported on all platforms. It will be skipped when searching for profiles on Windows Nano Server, Mac, and Linux platforms.

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? False
-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.
Required? False
Position? Named
Accept pipeline input? False
-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? False
-SecretKey <String>
The AWS secret key for the user account. This can be a temporary secret key if the corresponding session token is supplied to the -SessionToken parameter.
Required? False
Position? Named
Accept pipeline input? False
-SessionToken <String>
The session token if the access and secret keys are temporary session-based credentials.
Required? False
Position? Named
Accept pipeline input? False
-Region <String>
The system name of the AWS region in which the operation should be invoked. For example, us-east-1, eu-west-1 etc.
Required? False
Position? Named
Accept pipeline input? False
-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? False

Inputs

You can pipe a String object to this cmdlet for the FunctionName parameter.

Outputs

None or System.String
When you use the PassThru parameter, this cmdlet outputs the value supplied to the FunctionName parameter. Otherwise, this cmdlet does not return any output. The service response (type Amazon.Lambda.Model.DeleteFunctionResponse) can be referenced from properties attached to the cmdlet entry in the $AWSHistory stack.
