Helm Charts for Kubernetes

Helm is a package manager for Kubernetes, allowing you to define, install, and manage applications on Kubernetes easily. Helm uses a packaging format called Charts, which help you define a set of Kubernetes resources.

• Chart: A Helm package that contains all the necessary resource definitions for running an application, tool, or service.
• Release: A specific instance of a chart running in a Kubernetes cluster.
• Repository: A collection of charts that can be made available for installation.
• Values: Configuration settings for a chart that can be overridden during installation.

To install Helm, follow these steps:

1. Download the Helm binary from the official Helm website.
2. Unzip the downloaded file and move it to your PATH.
3. Initialize Helm in your Kubernetes cluster by running:

helm init

Creating a Helm chart can be done with the following command:

helm create mychart

This command generates a directory structure for your chart, including templates and a values file.

Modify the values.yaml file to set default configuration values for your application.

Consider the following best practices:

• Use version control for your Helm charts.
• Keep your charts modular by breaking them into smaller components.
• Use templates to manage environment-specific configurations.
• Test your charts using helm lint before deploying.
