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:

Linux$HOME/.cache/helm$HOME/.config/helm$HOME/.local/share/helm
