Container for the parameters to the UpdateFunctionCode operation. 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 You can't modify the code of a published version, only the unpublished version.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.

Properties
| Name | Type | Description | |
|---|---|---|---|
|
|
Architectures | System.Collections.Generic.List<System.String> |
Gets and sets the property Architectures.
The instruction set architecture that the function supports. Enter a string array
with one of the valid values (arm64 or x86_64). The default value is |
|
|
DryRun | System.Boolean |
Gets and sets the property DryRun. Set to true to validate the request parameters and access permissions without modifying the function code. |
|
|
FunctionName | System.String |
Gets and sets the property FunctionName. The name or ARN of the Lambda function. Name formats
The length constraint applies only to the full ARN. If you specify only the function name, it is limited to 64 characters in length. |
|
|
ImageUri | System.String |
Gets and sets the property ImageUri. URI of a container image in the Amazon ECR registry. Do not use for a function defined with a .zip file archive. |
|
|
Publish | System.Boolean |
Gets and sets the property Publish. Set to true to publish a new version of the function after updating the code. This has the same effect as calling PublishVersion separately. |
|
|
RevisionId | System.String |
Gets and sets the property RevisionId. Update the function only 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. |
|
|
S3Bucket | System.String |
Gets and sets the property S3Bucket. An Amazon S3 bucket in the same Amazon Web Services Region as your function. The bucket can be in a different Amazon Web Services account. Use only with a function defined with a .zip file archive deployment package. |
|
|
S3Key | System.String |
Gets and sets the property S3Key. The Amazon S3 key of the deployment package. Use only with a function defined with a .zip file archive deployment package. |
|
|
S3ObjectVersion | System.String |
Gets and sets the property S3ObjectVersion. For versioned objects, the version of the deployment package object to use. |
|
|
ZipFile | System.IO.MemoryStream |
Gets and sets the property ZipFile. The base64-encoded contents of the deployment package. Amazon Web Services SDK and CLI clients handle the encoding for you. Use only with a function defined with a .zip file archive deployment package. |
Examples
The following example replaces the code of the unpublished ($LATEST) version of a function named my-function with the contents of the specified zip file in Amazon S3.
To update a Lambda function's code
var response = client.UpdateFunctionCode(new UpdateFunctionCodeRequest
{
FunctionName = "my-function",
S3Bucket = "my-bucket-1xpuxmplzrlbh",
S3Key = "function.zip"
});
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;
