Which solution will meet these requirements with the LEAST management overhead?
Pull images from the public container registry. Publish the images to Amazon Elastic Container Registry (Amazon ECR) repositories with scan on push configured in a centralized AWS account. Use a CI/CD pipeline to deploy the images to different AWS accounts. Use identity-based policies to restrict access to which IAM principals can access the images.
Pull images from the public container registry. Publish the images to a private container registry that is hosted on Amazon EC2 instances in a centralized AWS account. Deploy host-based container scanning tools to EC2 instances that run Amazon ECS. Restrict access to the container images by using basic authentication over HTTPS.
Pull images from the public container registry. Publish the images to Amazon Elastic Container Registry (Amazon ECR) repositories with scan on push configured in a centralized AWS account. Use a CI/CD pipeline to deploy the images to different AWS accounts. Use repository policies and identity-based policies to restrict access to which IAM principals and accounts can access the images.
Pull images from the public container registry. Publish the images to AWS CodeArtifact repositories in a centralized AWS account. Use a CI/CD pipeline to deploy the images to different AWS accounts. Use repository policies and identity-based policies to restrict access to which IAM principals and accounts can access the images.
Explanations:
While this option uses Amazon ECR with scan on push and identity-based policies for access control, it does not specifically mention repository policies, which can provide more granular access controls compared to just using identity-based policies. This might lead to potential access issues.
This option involves hosting a private container registry on EC2 instances, which increases management overhead due to the need to manage EC2 instances and deploy host-based scanning tools. Additionally, basic authentication is not as secure or robust as AWS-native solutions.
This option correctly utilizes Amazon ECR with scan on push, a CI/CD pipeline for deployment, and employs both repository policies and identity-based policies for access control, ensuring only specific IAM roles and accounts can access the images with minimal management overhead.
Although AWS CodeArtifact can be used for storing container images and access control can be managed through policies, it is not specifically designed for container images like Amazon ECR. This could complicate management and does not leverage the best practices for container security scanning.
I deduce that the answer is:
Pull images from the public container registry. Publish the images to Amazon Elastic Container Registry (Amazon ECR) repositories with scan on push configured in a centralized AWS account. Use a CI/CD pipeline to deploy the images to different AWS accounts. Use repository policies and identity-based policies to restrict access to which IAM principals and accounts can access the images.
