AmazonLambdaClient.UpdateFunctionConfiguration Method (UpdateFunctionConfigurationRequest)

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 Lambda 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 You can't modify the configuration of a published version, only the unpublished version.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 Amazon Web Services account or Amazon Web Service, use AddPermission.

Note:

For .NET Core this operation is only available in asynchronous form. Please refer to UpdateFunctionConfigurationAsync.

Namespace: Amazon.Lambda

Syntax

public virtual UpdateFunctionConfigurationResponse UpdateFunctionConfiguration(
         UpdateFunctionConfigurationRequest request
)

Parameters

request: Type: Amazon.Lambda.Model.UpdateFunctionConfigurationRequest

Container for the necessary parameters to execute the UpdateFunctionConfiguration service method.

Return Value

Type: UpdateFunctionConfigurationResponse

The response from the UpdateFunctionConfiguration service method, as returned by Lambda.

Exceptions

Exception	Condition
CodeSigningConfigNotFoundException	The specified code signing configuration does not exist.
CodeVerificationFailedException	The code signature failed one or more of the validation checks for signature mismatch or expiry, and the code signing policy is set to ENFORCE. Lambda blocks the deployment.
InvalidCodeSignatureException	The code signature failed the integrity check. If the integrity check fails, then Lambda blocks deployment, even if the code signing policy is set to WARN.
InvalidParameterValueException	One of the parameters in the request is not valid.
PreconditionFailedException	The RevisionId provided does not match the latest RevisionId for the Lambda function or alias. Call the GetFunction or the GetAlias API operation to retrieve the latest RevisionId for your resource.
ResourceConflictException	The resource already exists, or another operation is in progress.
ResourceNotFoundException	The resource specified in the request does not exist.
ServiceException	The Lambda service encountered an internal error.
TooManyRequestsException	The request throughput limit was exceeded. For more information, see Lambda quotas.

Examples

The following example modifies the memory size to be 256 MB for the unpublished ($LATEST) version of a function named my-function.

To update a Lambda function's configuration


var response = client.UpdateFunctionConfiguration(new UpdateFunctionConfigurationRequest 
{
    FunctionName = "my-function",
    MemorySize = 256
});

string codeSha256 = response.CodeSha256;
long codeSize = response.CodeSize;
string description = response.Description;
string functionArn = response.FunctionArn;
string functionName = response.FunctionName;
string handler = response.Handler;
string lastModified = response.LastModified;
int memorySize = response.MemorySize;
string revisionId = response.RevisionId;
string role = response.Role;
string runtime = response.Runtime;
int timeout = response.Timeout;
TracingConfigResponse tracingConfig = response.TracingConfig;
string version = response.Version;
