AWS ECR Pull Through Cache

This module sets up AWS ECR to serve as a pull through cache for publicly available container images used in your Kubernetes clusters.

This provides several benefits:

• Significantly improves startup time of both new nodes and new pods by pulling from localized data storage rather than the public internet

• Improves resiliency to outages of public container registries which might otherwise cripple your infrastructure

• Avoids the risk of hitting the rate limits imposed by public registries

• Reduces costs associated with NAT gateways by keeping large image transfers inside your private network
