Verdaccio Charts for GKE

Verdaccio is a lightweight private NPM proxy registry.

TL;DR;

helm repo add verdaccio-gke-charts https://devintent.github.io/verdaccio-gke-charts/
helm repo update
helm install verdaccio-gke-charts/devintent-verdaccio-gke-charts

Introduction

This chart bootstraps a Verdaccio deployment on a Kubernetes cluster using the Helm package manager on GKE.

Prerequisites

1. Create a Google CLoud Project
2. Install the gcloud SDK and CLI or use the Cloud Shell
3. If using the CLI outside of Cloud Shell, run gcloud config set project your-project
4. Create a GKE cluster
5. Pick the cluster to work with using a command like
   • gcloud container clusters get-credentials verdaccio-autopilot-cluster --region=us-central1
6. Create a namespace (recommended)
   • kubectl create namespace registry
7. If not in the Cloud Shell, Install Helm v3+

Installing the Chart

Add repository

helm repo add verdaccio-gke-charts https://devintent.github.io/verdaccio-gke-charts

Install Verdaccio chart

In this example we use npm as release name:

# Helm v3+
helm install npm --namespace registry verdaccio-gke-charts/devintent-verdaccio-gke-charts

Deploy a specific Verdaccio version

helm install npm --set image.tag=4.6.2 verdaccio-gke-charts/devintent-verdaccio-gke-charts

Upgrading Verdaccio

helm upgrade npm --namespace registry verdaccio-gke-charts/devintent-verdaccio-gke-charts

The command deploys Verdaccio on the GKE cluster in the default configuration. The configuration section lists the parameters that can be configured during installation.

Tip: List all releases using helm list.

Uninstalling the Chart

To uninstall/delete the npm deployment:

helm uninstall npm --namespace registry

The command removes all the GKE and GCE components associated with the chart and deletes the release.

Specify each parameter using the --set key=value[,key=value] argument to helm install. For example,

helm install my-release --set service.type=LoadBalancer verdaccio-gke-charts/devintent-verdaccio-gke-charts

The above command sets the service type LoadBalancer.

Alternatively, a YAML file that specifies the values for the above parameters can be provided while installing the chart. For example,

helm install my-release -f values.yaml verdaccio-gke-charts/devintent-verdaccio-gke-charts

Tip: You can use the default values.yaml as a starting point.

Custom ConfigMap

When creating a new chart with this chart as a dependency, CustomConfigMap can be used to override the default config.yaml provided. It also allows for providing additional configuration files that will be copied into /verdaccio/conf. In the parent chart's values.yaml, set the value to true and provide the file templates/config.yaml for your use case.

Persistence

The Verdaccio image stores persistence under /verdaccio/storage path of the container. A dynamically managed Persistent Volume Claim is used to keep the data across deployments, by default. This is known to work in GCE, AWS, and minikube. Alternatively, a previously configured Persistent Volume Claim can be used.

It is possible to mount several volumes using Persistence.volumes and Persistence.mounts parameters.

Existing PersistentVolumeClaim

1. Create the PersistentVolume
2. Create the PersistentVolumeClaim
3. Install the chart

helm install npm \
    --set persistence.existingClaim=PVC_NAME \
    verdaccio-gke-charts/devintent-verdaccio-gke-charts
