Update Function Code

lambda_update_function_code R Documentation

Updates a Lambda function's code

Description

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 You can't modify the code of a published version, only the unpublished version.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.

Usage

lambda_update_function_code(FunctionName, ZipFile, S3Bucket, S3Key,
  S3ObjectVersion, ImageUri, Publish, DryRun, RevisionId, Architectures)

Arguments

FunctionName

[required] The name or ARN of the Lambda function.

Name formats

  • Function name – ⁠my-function⁠.

  • Function ARN – ⁠arn:aws:lambda:us-west-2:123456789012:function:my-function⁠.

  • Partial ARN – ⁠123456789012:function:my-function⁠.

The length constraint applies only to the full ARN. If you specify only the function name, it is limited to 64 characters in length.

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.

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

The Amazon S3 key of the deployment package. Use only with a function defined with a .zip file archive deployment package.

S3ObjectVersion

For versioned objects, the version of the deployment package object to use.

ImageUri

URI of a container image in the Amazon ECR registry. Do not use for a function defined with a .zip file archive.

Publish

Set to true to publish a new version of the function after updating the code. This has the same effect as calling publish_version separately.

DryRun

Set to true to validate the request parameters and access permissions without modifying the function code.

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.

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 x86_64.
