Helm calls its packages, charts these are sets of files that outline a related selection of Kubernetes resources.

In this step, you’ll create a configuration file for the registry deployment and install the registry to your cluster with the given config using the Helm package manager.ĭuring the course of this tutorial, you will use a configuration file called chart_values.yaml to override some of the default settings for the Docker registry Helm chart. Step 1 - Configuring and Installing the Docker Registry

Note: The domain names you use in this tutorial must differ from the one used in the How To Set Up an Nginx Ingress on DigitalOcean Kubernetes prerequisite tutorial. In this tutorial, we’ll refer to the A records as registry.your_domain and k8s-test.your_domain. If you are using DigitalOcean to manage your domain’s DNS records, consult How to Manage DNS Records to create A records. For a guide on how to do this, see How To Set Up an Nginx Ingress on DigitalOcean Kubernetes Using Helm.Ī domain name with two DNS A records pointed to the DigitalOcean Load Balancer used by the Ingress. The Nginx Ingress Controller and Cert-Manager installed on the cluster.

To do this, complete Step 1 of the How To Install Software on Kubernetes Clusters with the Helm 3 Package Manager tutorial. The Helm package manager installed on your local machine. To learn how to create a DigitalOcean Space and API keys, see How To Create a DigitalOcean Space and API Key. To learn how to create a Kubernetes cluster on DigitalOcean, see Kubernetes Quickstart.Ī DigitalOcean Space with API keys (access and secret).
Instructions on how to configure kubectl are shown under the Connect to your Cluster step shown when you create your cluster. For other platforms, visit the official website.Ī DigitalOcean Kubernetes cluster with your connection configuration configured as the kubectl default. For Ubuntu 18.04, follow Step 1 of the How To Install Git on Ubuntu 18.04 tutorial. Git installed on the machine that you’ll use to access the cluster. Otherwise, visit Docker’s website for other distributions.Īn account at Docker Hub for storing Docker images you’ll create during this tutorial. You only need to complete Step 1 and Step 2. For Ubuntu 18.04, visit How To Install and Use Docker on Ubuntu 18.04. Prerequisitesīefore you begin this tutorial, you’ll need:ĭocker installed on the machine that you’ll access your cluster from. At the end of this tutorial, you’ll have a secure, private Docker registry installed on your DigitalOcean Kubernetes cluster. You’ll create API keys for your designated Space, install the Docker registry to your cluster with custom configuration, configure Kubernetes to properly authenticate with it, and test it by running a sample deployment on the cluster. In this tutorial, you’ll deploy your private Docker registry to your DigitalOcean Kubernetes cluster using Helm, backed up by DigitalOcean Spaces for storing data. It has a built-in CDN network, which can greatly reduce latency when frequently accessing images.
DigitalOcean Spaces is an S3-compatible object storage designed for developer teams and businesses that want a scalable, simple, and affordable way to store and serve vast amounts of data, and is very suitable for storing Docker images. The default storage system is the local filesystem, but you can swap this for a cloud-based storage driver. The underlying registry storage is delegated to external drivers. By hosting your private Docker registry directly in your Kubernetes cluster, you can achieve higher speeds, lower latency, and better availability, all while having control over the registry. A private Docker registry allows you to securely share your images within your team or organization with more flexibility and control when compared to public ones. IntroductionĪ Docker registry is a storage and content delivery system for named Docker images, which are the industry standard for containerized applications.
