What is Container Registry?
A repository for storing, versioning, and distributing container images.
A Container Registry is a service for storing and distributing container images. Images are organized by repository and tagged with version identifiers. Public registries like Docker Hub host millions of open-source images. Private registries (AWS ECR, GitHub GHCR, GCP Artifact Registry) store proprietary images securely. Registries support vulnerability scanning, image signing, and access control policies.
