CNPG Helm Chart

This Helm chart deploys a CNPG (Cloud Native PostgreSQL) cluster on Kubernetes. It provides a customizable and scalable PostgreSQL database solution.

Prerequisites

• Kubernetes 1.16+
• Helm 3.0+

Installation

To install the chart, use the following command:

helm install <release-name> ./clusters

Replace <release-name> with your desired release name.

Configuration

The following table lists the configurable parameters of the CNPG chart and their default values:

Parameter	Description	Default
instances	Number of PostgreSQL instances in the cluster	3
postgresql.parameters.max_worker_processes	Maximum number of worker processes	60
storage.size	Size of the storage for each instance	1Gi

You can override these values by specifying them in a values.yaml file or directly in the command line using --set.

Accessing the Database

After installation, you can access the PostgreSQL database using the credentials stored in the Kubernetes secret. Use the following command to retrieve the username and password:

kubectl get secret <release-name>-app -o jsonpath="{.data.username}" | base64 --decode
kubectl get secret <release-name>-app -o jsonpath="{.data.password}" | base64 --decode

Uninstalling the Chart

To uninstall the chart, use the following command:
