Container Registry Management

This covers the essentials of managing container registries across Docker Hub, ECR, and GCR, with a strong emphasis on AWS ECR workflows. You get image scanning on push, retention policies to avoid drowning in old builds, and access control patterns that actually matter. The examples show practical setups like immutable tags and KMS encryption, plus image signing with Notary if you need that level of verification. It's built for teams running production containers who need to keep their registry secure and costs under control. The monitoring and multi-region replication guides are solid additions if you're scaling beyond a single deployment.
