Productiv9 Charts

This Helm chart is designed to deploy a suite of applications including Ghost (a powerful blogging platform), Litestream (for real-time SQLite replication), Rclone (for command-line cloud storage synchronization), and Cloudflared (for secure network tunnels). This configuration is tailored for high availability, secure access, and persistent storage, making it ideal for production environments.

Prerequisites

Kubernetes 1.19+
Helm 3.0+
PV provisioner support in the underlying infrastructure (for persistent storage)
A Cloudflare account and a configured tunnel token for cloudflared
A sendgrid account for sending email

Customizing the Chart Before Installing

To configure the chart with custom values:

Create a file named my-values.yaml with your changes.

For example:

cloudflared:
  token: "<your-cloudflared-token>"
ghost:
  url: "https://yourdomain.com"
  sendgridApiKey: "<your-sendgrid-api-key>"

Install the chart with the custom values:

helm install my-release productiv9/<chart-name> -f my-values.yaml

Upgrading Your Deployment

To upgrade your deployment with a new version of the chart or to change the configuration:

helm upgrade my-release productiv9/ghost -f my-values.yaml

Persistence

The Ghost application is configured to use a Persistent Volume Claim (PVC) to store data. The size of the PVC is configurable through the volumeClaims.ghostContent.size parameter.
