Helm & Operators in Neo4j

Introduction

This lesson provides an overview of using Helm and Operators in managing Neo4j deployments on Kubernetes.

What is Helm?

Helm is a package manager for Kubernetes, helping you define, install, and upgrade even the most complex Kubernetes applications.

Note: Helm uses a packaging format called charts, which are collections of files that describe a related set of Kubernetes resources.

What are Operators?

Operators are a method of packaging, deploying, and managing Kubernetes applications. They extend Kubernetes' capabilities to manage complex applications.

Tip: Operators use custom resources to manage applications and their components.
