Network.AWS.Lambda.GetFunctionConfiguration

Returns the configuration information of the Lambda function. This the same information you provided as parameters when uploading the function by using CreateFunction.

You can use the optional Qualifier parameter to retrieve configuration information for a specific Lambda function version. If you don't provide it, the API returns information about the $LATEST version of the function. For more information about versioning, see AWS Lambda Function Versioning and Aliases.

This operation requires permission for the 'lambda:GetFunctionConfiguration' operation.

See: AWS API Reference for GetFunctionConfiguration.

Creating a Request

getFunctionConfiguration

Arguments

:: Text

gfcFunctionName

-> GetFunctionConfiguration

Creates a value of GetFunctionConfiguration with the minimum fields required to make a request.

Use one of the following lenses to modify other fields as desired:

• gfcQualifier
• gfcFunctionName

data GetFunctionConfiguration

See: getFunctionConfiguration smart constructor.

Request Lenses

gfcQualifier :: Lens' GetFunctionConfiguration (Maybe Text)

Using this optional parameter you can specify function version or alias name. If you specify function version, the API uses qualified function ARN and returns information about the specific function version. if you specify alias name, the API uses alias ARN and returns information about the function version to which the alias points.

If you don't specify this parameter, the API uses unqualified function ARN, and returns information about the $LATEST function version.

gfcFunctionName :: Lens' GetFunctionConfiguration Text

The name of the Lambda function for which you want to retrieve the configuration information.

You can specify an unqualified 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"). AWS Lambda also allows you to specify only 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 character in length.

Destructuring the Response

functionConfiguration :: FunctionConfiguration

Creates a value of FunctionConfiguration with the minimum fields required to make a request.

Use one of the following lenses to modify other fields as desired:

• fcMemorySize
• fcRuntime
• fcFunctionARN
• fcRole
• fcVersion
• fcFunctionName
• fcCodeSize
• fcHandler
• fcTimeout
• fcLastModified
• fcCodeSha256
• fcDescription

Response Lenses

fcMemorySize :: Lens' FunctionConfiguration (Maybe Natural)

The memory size, in MB, you configured for the function. Must be a multiple of 64 MB.

fcRuntime :: Lens' FunctionConfiguration (Maybe Runtime)

The runtime environment for the Lambda function.

fcFunctionARN :: Lens' FunctionConfiguration (Maybe Text)

The Amazon Resource Name (ARN) assigned to the function.

fcRole :: Lens' FunctionConfiguration (Maybe Text)

The Amazon Resource Name (ARN) of the IAM role that Lambda assumes when it executes your function to access any other Amazon Web Services (AWS) resources.

fcVersion :: Lens' FunctionConfiguration (Maybe Text)

The version of the Lambda function.

fcFunctionName :: Lens' FunctionConfiguration (Maybe Text)

The name of the function.

fcCodeSize :: Lens' FunctionConfiguration (Maybe Integer)

The size, in bytes, of the function .zip file you uploaded.

fcHandler :: Lens' FunctionConfiguration (Maybe Text)

The function Lambda calls to begin executing your function.

fcTimeout :: Lens' FunctionConfiguration (Maybe Natural)

The function execution time at which Lambda should terminate the function. Because the execution time has cost implications, we recommend you set this value based on your expected execution time. The default is 3 seconds.

fcLastModified :: Lens' FunctionConfiguration (Maybe Text)

The timestamp of the last time you updated the function.

fcCodeSha256 :: Lens' FunctionConfiguration (Maybe Text)

It is the SHA256 hash of your function deployment package.

fcDescription :: Lens' FunctionConfiguration (Maybe Text)

The user-provided description.
