How To Install A Private Docker Container Registry In Kubernetes
Introduction
Hosting a Docker private registry gives you full control over the storage location of your images and how you can access them. This is especially useful if you develop private projects that shouldn't be publicly on Docker Hub.
In this tutorial, you will learn how to install a private Docker registry in any Kubernetes cluster. It is a follow-up of a tutorial previously released on this blog because it will use a Traefik Ingress Controller to expose the Docker registry.
Preparation
Create Kubernetes Namespace
The first step is to create a Kubernetes namespace where all resources will be applied during this tutorial:
kubectl create namespace docker-registryPersistentVolumeClaim
In this section, you will mount a volume into a dedicated Kubernetes Pod using a PersistentVolumeClaim. A PersistentVolumeClaim (PVC) is a Kubernetes resource to use a pre-defined abstract PersistentVolume (PV) storage without exposing how those volumes are implemented.
