Container Registry

A registry is where your software lives – as an image, versioned and ready to deploy.

For developers: a place to store builds.
For ops teams: a central tool.
For decision-makers: a way to gain control and security.
And for us: a core part of automated infrastructure.

Why is the registry so important?

Modern software isn’t deployed as source code anymore – it’s shipped as a container image.
These images must be stored, versioned, and distributed reliably.

The registry is the hub of this process:

  • No registry, no image
  • No image, no deployment
  • No deployment, no production

A registry enables:

  • Reproducibility – every deployment is based on a defined version
  • Traceability – who deployed what, when, and how
  • Security – via access control, TLS & image signing
  • Efficiency – with layer reuse & caching

What makes a registry?

Think of it like a package manager (npm, pip) – but for containers:

  • Images can be pushed, pulled, tagged, and managed
  • Supports public & private repositories
  • Works seamlessly with CI/CD, Kubernetes, and more

Examples include:

  • Docker Hub – public and centralized
  • GitLab Registry – built into DevOps workflows
  • Harbor – self-hosted, enterprise-ready
  • Forgejo/Gitea Registry – lightweight and open-source

Registry vs. File Server

Container images consist of multiple layers. A proper registry:

  • understands the image format
  • reuses layers efficiently (caching)
  • supports APIs, tagging & authentication
  • integrates with CI/CD and deployment tools

A file server can’t do any of that.

How we handle registries at RiKuWe

We operate registries for our clients – secure, maintainable, transparent:

  • Fully managed with TLS, auth, backups & cleanup
  • Or integrated into existing systems (GitLab, Harbor, etc.)
  • Tightly connected with CI/CD, PPO/PO environments, and Kubernetes

Your team builds software –
we make sure the images get where they need to go, safely.

Frequently Asked Questions

What is a container registry?

A registry is a central storage location for container images. It allows you to store, version, and distribute images for deployment.

Why do I need a registry?

Without a registry, you can’t deploy or deliver container images. It’s essential for automated deployments, traceability, and secure workflows.

How is a registry different from a file server?

A registry understands container image formats – including layers, tags, and metadata. A file server doesn’t support this functionality.

Which registries does RiKuWe use?

We primarily use Harbor – self-hosted, secure, and multi-tenant-ready. Depending on the project, we also integrate GitLab or Forgejo registries. Public registries like Docker Hub are used selectively and with strict security policies.

Can I run my own registry?

Yes – but you’ll need to plan for authentication, TLS, backups, and cleanup. We support setup, operation, or integration.
