Docker Registry

Introduction

Docker Registry is a stateless, highly scalable server-side application that stores and lets you distribute Docker images. It is open-source, licensed under the Apache-2.0 license.

This Helm chart deploys a private Docker Registry on Kubernetes, allowing you to store and manage your container images within your own infrastructure.

Installation

To install Docker Registry, run:

make install

Usage

After installation, you can push and pull images from the registry:

# Port forward to access registry locally
kubectl port-forward svc/registry -n registry 5000:5000

# Tag an image for your private registry
docker tag my-image localhost:5000/my-image

# Push to your private registry
docker push localhost:5000/my-image

# Pull from your private registry
docker pull localhost:5000/my-image
