Helm Chart Repository with GitHub Pages

What is Helm

Helm is a package manager for Kubernetes that simplifies the deployment and management of applications on a Kubernetes cluster. It allows users to define, install, and upgrade complex Kubernetes applications with just a few commands. Helm provides a way to package Kubernetes manifests, templates, and other resources into a single deployable unit called a chart.

1. Create new repository on GitHub to upload Helm Chart and Helm Package files

2. Commit Helm chart files to the newly created Repository on GitHub.


Need to execute below HELM commands
from terminal with helm binary installed

3. helm lint is a command in Helm, a package manager for Kubernetes, that checks a Helm chart for potential issues before deploying it to a Kubernetes cluster.
helm lint observability/
4. helm package a distributable package from a Helm chart. The helm package command takes a directory containing a chart and creates a compressed package, or "tgz" file, that includes all the files necessary to install the chart on a Kubernetes cluster.
helm package observability/
5. The repository index is a YAML file called index.yaml, located at the root of the chart repository. It contains a list of chart entries, with each entry providing metadata about the chart, such as its name, version, and URL to download the chart package.
helm repo index --url https://intverse.github.io/observability/ .
cat index.yaml

apiVersion: v1
entries:
observability: -
apiVersion: v2
appVersion: 1.0.0

6. Commit index.yaml and observability-1.0.0.tgz to GitHub repository.

7. Now is the time to publish the helm chart from GitHub pages. Click settings on the GitHub repository, scroll to pages and select the branch to start publishing the helm package.

8. helm repo add is a command to add a new chart repository to your local Helm client. The helm repo add command requires two arguments: the name of the repository and its URL.
helm repo add intverse-repo https://intverse.github.io/observability
9. A chart is a package containing all the necessary files and metadata to deploy an application or service to a Kubernetes cluster. helm install is the command used in the Helm package manager to install a chart onto a Kubernetes cluster. The helm install command requires two arguments: the name of the release and the name of the chart to install.
helm install monitoring intverse-repo/observability
