Helm chart for a Docker registry. Successor to stable/docker-registry chart.

Docker Registry Helm Chart

This directory contains a Kubernetes chart to deploy a private Docker Registry.

Prerequisites Details

• PV support on underlying infrastructure (if persistence is required)

Chart Details

This chart will do the following:

• Implement a Docker registry deployment

Installing the Chart

First, add the repo:

$ helm repo add twuni https://helm.twun.io

To install the chart, use the following:

$ helm install twuni/docker-registry
