Helm for Kubernetes
Understand Helm charts, releases, and repositories so you can package and install Kubernetes applications more efficiently.
What Is Helm?
Helm is often called the package manager for Kubernetes. It helps you install, configure, and upgrade applications using reusable templates called charts.
Core Terms
| Term | Meaning |
|---|---|
| Chart | A package of Kubernetes templates and metadata |
| Release | A specific installed instance of a chart |
| Repository | A collection of charts |
Helm 3 Architecture
Helm 3 is client-side and does not use Tiller. That made Helm simpler and reduced some past security concerns.
Why Teams Use Helm
- reusable app packaging
- environment-specific values
- easier upgrades and rollbacks
- standard way to distribute common stacks like Prometheus or NGINX Ingress
