universal-helm-charts

Overview

This work aims to streamline Kubernetes deployments across multiple services by reducing code duplication and ensuring consistency. This umbrella Helm chart encapsulates common configurations and functionalities, facilitating a DRY (Don't Repeat Yourself) approach and simplifying Kubernetes deployments.

The repo is structured into two main parts:

Library Chart: Contains reusable definitions and templates for common Kubernetes resources.
Base Chart: Utilizes the library chart to provide a standardized deployment template for applications.

This approach simplifies the Kubernetes deployment process, enabling rapid and consistent deployments across various environments and services.

Structure

library/: A Helm library chart containing templates for common Kubernetes resources like ConfigMaps and HPAs.
base-chart/: A Helm chart that serves as the base for deploying microservices. It includes the library chart as a dependency.

Features

Centralized Configuration: Manage common configurations across all microservices in one place.
Modular Design: Extend and customize configurations to meet the specific needs of each microservice.
Scalability: Designed to support deployments of any scale, from small to large enterprises.
Best Practices: Integrates Kubernetes and Helm best practices to provide a solid deployment foundation.

Getting Started

Prerequisites

Helm version 3.x or later
Access to a Kubernetes cluster
Basic knowledge of Kubernetes and Helm concepts

Installation

Clone the repository:

git clone git@github.com:Salaton/universal-helm-charts.git
cd universal-helm-charts

Install the Helm chart:
```
helm install my-microservices ./unified-chart -f custom-values.yaml
```
Replace my-microservices with your deployment name and custom-values.yaml with your specific configuration file.

Usage

To deploy a microservice using the base chart, you can define your service-specific configurations in a values.yaml file. For example:

configMap:
  name: myservice-config
  data:
    setting1: "value1"

hpa:
  enabled: true
  name: myservice-hpa
  targetRef:
    name: myservice
  minReplicas: 2
  maxReplicas: 5
  metrics:
    - type: Resource
      resource:
        name: cpu
        target:
          type: Utilization
          averageUtilization: 75

Then, deploy your microservice using Helm:

`helm install myservice ./base-chart -f values.yaml`
