Top 10 Container Registry
Container registries store and distribute OCI container images across teams and deployment pipelines. They provide versioning, access control, and vulnerability scanning for container artefacts.
Why this category matters
A container registry is the distribution hub between image builds and deployments. It enables immutable image tags, replication across regions, and security scanning before images reach production clusters.
When to use these tools
You need a container registry as soon as you start building container images in CI. Cloud-native registries are sufficient for most teams; self-hosted registries are preferred for air-gapped or compliance-driven environments.

Container Registry — FAQ
What is the difference between Docker Hub and a private registry?
Docker Hub is a public registry hosting millions of community and vendor images. A private registry stores your own proprietary images behind access controls.
Does Harbor replace Docker Hub?
Harbor is a self-hosted private registry with built-in vulnerability scanning, replication, and RBAC. It complements rather than replaces Docker Hub for private image storage.
Which registry should I use with AWS EKS?
AWS ECR integrates natively with EKS and IAM, making it the natural choice. It supports lifecycle policies, image scanning, and cross-account access.
