Repository for the Kubernetes + Helm templating tool lab

Create and Use a Package using the Helm Templating Tool

Overview

The team had been struggling to manage various manifest files involved in running a Kubernetes cluster. The app exposes the weather services of a city using RESTful APIs. The manager wants to explore the solution of packaging them and deploying them as a single package. You are a Kubernetes Administrator tasked with defining multiple Kubernetes objects as a Helm chart. You will create a Helm chart that includes the deployment and service definitions for the app. Next, you will install the Helm chart to create the Kubernetes resources for the app. Finally, you will verify the installation by checking the API to fetch the sample weather details.

Learning Objectives

• Awareness of manifest management and common templating tools.
• Configure Helm in the Kubernetes cluster.
• Create a Helm chart file containing deployment and service definitions.
• Install the Helm chart to create Kubernetes resources.
