Helm is a tool for templating Kubernetes resource definitions. Some say, it is a package manager because it can be also used to deploy and manage releases of Kubernetes applications.

• An application chart is a collection of templates that define the Kubernetes resources for an application.
• A library chart is a collection of reusable functions and templates.

Generate the resource definitions based on the defined templates in the chart.

helm template $chart

Upgrades the deployed release with the provided chart. The --install flag deploys the release if it is not deployed already.

helm upgrade --install $release_name $chart

Lists all of the releases for a specified namespace

helm list -n default
