Updates a Lambda function's code. If code signing is enabled for the function, the code package must be signed by a trusted publisher. For more information, see Configuring code signing for Lambda.
If the function's package type is Image, then you must specify the code package
in ImageUri as the URI of a container
image in the Amazon ECR registry.
If the function's package type is Zip, then you must specify the deployment
package as a .zip
file archive. Enter the Amazon S3 bucket and key of the code .zip file location.
You can also provide the function code inline using the ZipFile field.
The code in the deployment package must be compatible with the target instruction
set architecture of the function (x86-64 or arm64).
The function's code is locked when you publish a version. You can't modify the code of a published version, only the unpublished version.
For a function defined as a container image, Lambda resolves the image tag to an image digest. In Amazon ECR, if you update the image tag to a new image, Lambda does not automatically update the function.
This is an asynchronous operation using the standard naming convention for .NET 4.5 or higher. For .NET 3.5 the operation is implemented as a pair of methods using the standard naming convention of BeginUpdateFunctionCode and EndUpdateFunctionCode.
Namespace: Amazon.Lambda
Assembly: AWSSDK.Lambda.dll
Version: 3.x.y.z
public abstract Task<UpdateFunctionCodeResponse> UpdateFunctionCodeAsync( UpdateFunctionCodeRequest request, CancellationToken cancellationToken )
Container for the necessary parameters to execute the UpdateFunctionCode service method.
A cancellation token that can be used by other objects or threads to receive notice of cancellation.
| Exception | Condition |
|---|---|
| CodeSigningConfigNotFoundException | The specified code signing configuration does not exist. |
| CodeStorageExceededException | Your Amazon Web Services account has exceeded its maximum total code size. For more information, see Lambda quotas. |
| 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. |
