-This command starts a local chart repository server that serves charts from a local directory.
-
-The new server will provide HTTP access to a repository. By default, it will
-scan all of the charts in '$HELM_HOME/repository/local' and serve those over
-the local IPv4 TCP port (default '127.0.0.1:8879').
-
-This command is intended to be used for educational and testing purposes only.
-It is best to rely on a dedicated web server or a cloud-hosted solution like
-Google Cloud Storage for production use.
