Introduction

Now that we’ve grasped the significance of the Helm in Kubernetes, let’s dive into the practical aspects. In this second part of the “Helm for Beginners” series, we’ll guide you through the process of installing Helm on your local machine and a Kubernetes cluster. Additionally, we’ll walk through creating a basic Helm chart and deploying it to the cluster. So, let’s get started on the path to Helm mastery!

Installing Helm

1. Local Machine Installation:
– On your local machine, you can install Helm using package managers like Homebrew on macOS or Chocolatey on Windows.

     Example for Homebrew on macOS
     brew install helm
     

2. Kubernetes Cluster Installation:
– For the Kubernetes cluster, Helm operates as a client-server application. The server-side component, known as Tiller in Helm 2, has been deprecated in Helm 3. In Helm 3, Tiller is no longer required, simplifying the installation process.

     Example for Helm 3 on a Kubernetes cluster
     kubectl apply -f https://raw.githubusercontent.com/helm/helm/master/scripts/get-helm-3
     

Setting Up Your First Chart

1. Creating a Helm Chart:
– Use the Helm CLI to create a new chart. This generates the necessary directory structure for your chart.

     helm create my-first-chart
     

2. Chart Structure Overview:
– Explore the structure of the newly created chart. Key files include `Chart.yaml` for chart metadata, `values.yaml` for default configuration values, and the `templates` directory for Kubernetes manifest templates.

3. Customizing Your Chart:
– Open `values.yaml` to customize default values such as image names, ports, and other configuration parameters.

4. Deploying Your Chart:
– Use the Helm CLI to install your chart on the Kubernetes cluster.

     cd my-first-chart
     helm install my-first-release .
     

5. Verifying the Deployment:
– Confirm that your chart has been successfully deployed by checking the status of your release.

     helm status my-first-release
     

Conclusion

Congratulations! You’ve now installed Helm on your local machine and Kubernetes cluster and successfully deployed your first Helm chart. This marks the beginning of your Helm journey, where the ability to package, version, and deploy applications becomes a seamless experience. In the upcoming parts of this series, we’ll delve deeper into Helm concepts, explore advanced chart customization, and guide you through the intricacies of managing releases. Stay tuned as we uncover more about Helm’s capabilities and empower you to become a proficient Helm user!
