Helm

Helm is the package manager for Kubernetes, enabling declarative application packaging, versioned chart releases, OCI registry distribution, and automated rollbacks.

When to Use

• Kubernetes Package Management: Packaging, templating, versioning, and deploying complex Kubernetes applications.
• Multi-Environment Value Overrides: Reusing a single chart across dev, staging, and production with distinct values.yaml files.
• Third-Party Open-Source Deployment: Installing community software (Cert-Manager, Ingress-Nginx, Prometheus) via Helm Repos.
• Release Lifecycle & Rollbacks: Upgrading, tracking release revisions, and executing automated rollbacks via helm rollback.

Quick Start

# Install a chart
helm install my-release oci://registry-1.docker.io/bitnamicharts/nginx
