Exception thrown by lambda_client.update_function_code when deploying a multi-architecture container

[tim0git]

Describe the bug

SDK call:
lambda_client.update_function_code(FunctionName=lambda_function_name, ImageUri=image_uri, Publish=True, Architectures=["arm64"])

OR

lambda_client.update_function_code(FunctionName=lambda_function_name, ImageUri=image_uri, Publish=True, Architectures=["x86_64"])

Exception thrown:
botocore.errorfactory.InvalidParameterValueException: An error occurred (InvalidParameterValueException) when calling the UpdateFunctionCode operation: The image manifest or layer media type for the source image 1234567891.dkr.ecr.eu-west-1.amazonaws.com/example-application@sha256:f4ecc543fa7e161acf2775d56c3d0a1f902601fcdffc9d8be1aaa5cfffd3429d is not supported.

I have build the multi arch images and manifest following this blog post:
https://aws.amazon.com/blogs/devops/creating-multi-architecture-docker-images-to-support-graviton2-using-aws-codebuild-and-aws-codepipeline/

Expected Behavior

I expect the SDK call to update the function code without throwing an exception.

Current Behavior

Exception thrown:
botocore.errorfactory.InvalidParameterValueException: An error occurred (InvalidParameterValueException) when calling the UpdateFunctionCode operation: The image manifest or layer media type for the source image 1234567891.dkr.ecr.eu-west-1.amazonaws.com/example-application@sha256:f4ecc543fa7e161acf2775d56c3d0a1f902601fcdffc9d8be1aaa5cfffd3429d is not supported.

Reproduction Steps

Build multi arch container following these steps:
https://aws.amazon.com/blogs/devops/creating-multi-architecture-docker-images-to-support-graviton2-using-aws-codebuild-and-aws-codepipeline/

Attempt to update an existing container lambda with the latest tag from the ECR.

Possible Solution

No response

Additional Information/Context

No response

SDK version used

boto3 version 1.21.18

Environment details (OS name and version, etc.)

Python version 3.9, CodeBuild Image: aws/codebuild/amazonlinux2-x86_64-standard:3.0

Hi @tim0git thanks for reaching out. There was also a question in re:Post here on the same topic. An AWS representative recently posted this comment there:

As of this writing, AWS Lambda does not yet support multi-arch container images. It only supports single-image manifests, and the image architecture must match the compute architecture

They also referenced a note here in the documentation:

You create each container image to be compatible with one of the instruction set architectures that Lambda supports. Lambda provides base images for each of the instruction set architectures and Lambda also provides base images that support both architectures.

The image that you build for your function must target only one of the architectures.

I’m converting this issue to a discussion per our guidance process. Please let me know if you have any follow up questions.

Brilliant. Thankyou for clearing that up for me. I feel foolish as the answers are in the docs. You have explained it perfectly.
