Helm Chart for pgAdmin

Introduction

This Helm chart installs pgAdmin in a Kubernetes cluster.

Prerequisites

• Kubernetes cluster 1.10+
• Helm 2.8.0+
• PV provisioner support in the underlying infrastructure.

Installation

Add Helm repository

helm repo add cetic https://cetic.github.io/helm-charts
helm repo update

Configure the chart

The following items can be set via --set flag during installation or configured by editing the values.yaml directly (need to download the chart first).

Configure the way how to expose pgAdmin service:

• Ingress: The ingress controller must be installed in the Kubernetes cluster.
• ClusterIP: Exposes the service on a cluster-internal IP. Choosing this value makes the service only reachable from within the cluster.
• NodePort: Exposes the service on each Node’s IP at a static port (the NodePort). You’ll be able to contact the NodePort service, from outside the cluster, by requesting NodeIP:NodePort.
• LoadBalancer: Exposes the service externally using a cloud provider’s load balancer.

Configure the way how to persistent data:

• Disable: The data does not survive the termination of a pod.
• Persistent Volume Claim(default): A default StorageClass is needed in the Kubernetes cluster to dynamic provision the volumes. Specify another StorageClass in the storageClass or set existingClaim if you have already existing persistent volumes to use.

Install the chart

Install the pgAdmin helm chart with a release name my-release:

helm install --name my-release cetic/pgadmin

Uninstallation

To uninstall/delete the my-release deployment:

helm delete --purge my-release
