Helm is a package manager for Kubernetes that simplifies the deployment and management of applications. This guide covers installing Helm, configuring repositories, and using it to deploy packages on CentOS Stream 10.

Download Helm

Download the latest Helm binary from the official GitHub release page:

curl -fsSL -o get_helm.sh https://raw.githubusercontent.com/helm/helm/main/scripts/get-helm-3
chmod +x get_helm.sh
./get_helm.sh

Verify Installation

Check the installed Helm version:

helm version

Expected output similar to:

version.BuildInfo{Version:"v3.17.x", GitCommit:"...", GitTreeState:"clean", GoVersion:"go1.24.x"}

Add Repositories

Add the official stable repository and update:

helm repo add stable https://charts.helm.sh/stable
helm repo update

Search for available charts:

helm search repo stable

Install a Package

Example: installing the NGINX Ingress Controller using Helm:

helm repo add ingress-nginx https://kubernetes.github.io/ingress-nginx
helm repo update
helm install ingress-nginx ingress-nginx/ingress-controller

Manage Releases

List installed Helm releases:

helm list

Upgrade a release:

helm upgrade ingress-nginx ingress-nginx/ingress-controller

Uninstall a release:

helm uninstall ingress-nginx

Helm Chart Structure

A Helm chart has the following directory structure:

mychart/
├── Chart.yaml          # Chart metadata
├── values.yaml         # Default configuration values
├── templates/          # Kubernetes manifest templates
│   ├── deployment.yaml
│   ├── service.yaml
│   └── _helpers.tpl    # Template helpers
└── charts/             # Sub-chart dependencies

Create a Chart

Create a new chart from scratch:

helm create mychart

Package a chart for distribution:

helm package mychart

Add a Repository from a Chart Museum

If you have a private chart repository:

helm repo add myrepo https://charts.example.com
helm repo update
helm install myapp myrepo/myapp

Conclusion

Helm streamlines Kubernetes application management. With Helm, you can define, install, and upgrade even the most complex Kubernetes applications using reusable chart packages.
