AWS Lambda Now Supports Cross-Account Container Images in AWS GovCloud (US) Regions

AWS Lambda now supports creating or updating functions using container images stored in an Amazon Elastic Container Registry (ECR) repository located in a different AWS account than the Lambda function in all AWS GovCloud Regions (US) (AWS GovCloud (US-West) and AWS GovCloud (US-East)). Previously, users could only access container images within the same AWS account as their Lambda function. This often required copying images to a local ECR repository if they were stored in a centralized account.

This enhancement streamlines the process by allowing access to container images across different accounts. To achieve this, you need to grant necessary permissions to the Lambda resource and the Lambda service principal. This functionality is available in all AWS Regions where both Lambda and ECR are available. See the AWS Region table for more info. Visit the AWS Lambda documentation for further details on configuring these permissions
