Helm Installation

Here we are going to learn how to install helm and why we are helm in DIGIT-DevOps

Before installing Helm you need to know about Yaml files. Yaml file: Yaml files (Yet Another Markup Language) are used to transmit the data in web applications. Json file: Json files (JavaScript Object Notation) are a standard text-based format to view the structured data of javascript object syntax.

JSON and YAML files are both used to transfer data between web applications. The key difference is that YAML files use indentation similar to Python to indicate the level of your code, unlike JSON.


  1. Git (please visit the GitOps page if you haven't installed Git).

  2. Install Visual Studio https://code.visualstudio.com/download IDE Code for better code visualization/editing capabilities

  3. Install Golang https://go.dev/doc/install#download(required version:V1.13.3)

  4. Kubectl (see working with Kubernetes page to install kubectl)

  • What is helm? helm can be defined as a . It is used to deploy (to extend) the applications and services easily into the Kubernetes cluster in the form of Helm charts.

  • What are helm charts? It and a file containing variables used to fill these templates based on the custom values and configurations.

  • Why are we using helm in DIGIT?

    1. Greatly improved productivity

    2. Reduced complexity of deployments

    3. More streamlined CI/CD pipeline

Helm charts are written in YAML and contain everything your developers need to deploy a container to a Kubernetes cluster. You may be used to creating Pods, Deployments, Services etc. in Kubernetes via the kubectl create command. This way of creating objects is indeed valid and great for learning purposes. However, when running Kubernetes in production you often want to have all your objects defined as .yaml files. This makes it easier for others to know what’s running in the cluster and allows for your deployments to be version-controlled.
