Common Actions for Helm

• helm search: search for charts
• helm pull: download a chart to your local directory to view
• helm install: upload the chart to Kubernetes
• helm list: list releases of charts

Environment variables:

Helm stores cache, configuration, and data based on the following configuration order:

• If a HELM*HOME environment variable is set, it will be used
• Otherwise, on systems supporting the XDG base directory specification, the XDG variables will be used
• When no other location is set a default location will be used based on the operating system

By default, the default directories depend on the Operating System. The defaults are listed below:
