Automating secure container registry management for air-gapped AWS workloads
AWS describes an approach for migrating Helm charts and container images into private Amazon ECR repositories inside air-gapped VPCs. It uses ECR repository creation templates, applied through Terraform, to set customer-managed KMS encryption, immutable tags and lifecycle rules on repositories created on first push. A migration tool called ecr-artifact-manager, included in the sample repository, preserves multi-architecture manifests, rewrites Helm chart references, and pulls private source credentials from AWS Secrets Manager.
What changes for platform teams
Platform teams in regulated air-gapped AWS environments can define repository security settings once in Terraform and have new repositories inherit them, rather than configuring each repository by hand. Teams should note that the encryption configuration cannot be changed after repository creation, and that enhanced scanning is configured at the registry level, not in the template.
