Ensure to enable ECR image scan

It is better to enbale ECR image scan. AWS ECR provides a feature to scan container images and discover vulnerable software.

Review your AWS Amazon ECR settings

In addition to the above, there are other security points you should be aware of making sure that your .tf files are protected in Shisho Cloud.

AWS::ECR::ReplicationConfiguration (CloudFormation)

The ReplicationConfiguration in ECR can be configured in CloudFormation with the resource name AWS::ECR::ReplicationConfiguration. The following sections describe 1 example of how to use the resource and its parameters.

Example Usage from GitHub

template.json#L1815
    "AWS::ECR::ReplicationConfiguration": {
      "Type": "AWS::ECR::ReplicationConfiguration",
      "Properties": {}
    },
    "AWS::QLDB::Ledger": {
      "Type": "AWS::QLDB::Ledger",

Parameters

>> from AWS CloudFormation Documentation

Explanation in CloudFormation Registry

The AWS::ECR::ReplicationConfiguration resource creates or updates the replication configuration for a private registry. The first time a replication configuration is applied to a private registry, a service-linked IAM role is created in your account for the replication process. For more information, see Using Service-Linked Roles for Amazon ECR in the Amazon Elastic Container Registry User Guide.

Note When configuring cross-account replication, the destination account must grant the source account permission to replicate. This permission is controlled using a private registry permissions policy. For more information, see AWS::ECR::RegistryPolicy.
