Gardener communtiy consolidates Gardener components as consumable helmcharts. The charts released in Gardener Charts provide a starting point for a Gardener deployment. Moreover, a chart for Cloudprofiles is maintained here. Feel free to open a PR to introduce your cloudprofiles, too.
A public demo Gardener installation using the resources defined here, can be found on Okeanos. On Okeanos, you are able to create Kubernetes clusters seamlessly, if you bring your own cloud credentials for any supported public cloud.
