In the "Library" Catalog, Application charts that are tagged as "Partner" are those that have been created and provided by an organization that is a Rancher Labs Partner.
The Rancher Labs Partner has verified these charts and certify the integration to the extent of being able to launch application with default configurations. And, it is to this extent that the Rancher Support applies.
Rancher Support does not apply to issues within the application and its lifecycle management. Rancher Support may refer Customer to the Partner, who maintains the chart, for issue resolution.
