pinniped-concierge provides a generic API for mapping an external

authenticating to the Kubernetes API.
Usage:
pinniped-concierge [flags]
Flags:
-c, --config string path to configuration file (default "pinniped.yaml")
--downward-api-path string path to Downward API volume mount (default "/etc/podinfo")
-h, --help help for pinniped-concierge
