[Rancher] Will Rancher fix problems root-caused to be in nginx?

Rancher will do one of the following, to help Customer resolve the issue root-caused to be in nginx:

• Should the issue have been resolved in a later version of nginx, Rancher will recommend Customer to upgrade to this version, along with the necessary upgrades to versions of Rancher and Kubernetes that has been certified for this later version of nginx.
• If the issue is unresolved in any acceptable nginx product versions, Rancher will advise Customer to contact nginx directly for issue resolution. Should a new version or patch be provided by nginx, Rancher will validate its relevant product versions on the new version or patch and certify it as supported for Customer deployment.

Note:

Inclusion of nginx as a certified component in the Rancher support matrix, is based on Rancher's own testing and validation of nginx with its default configuration settings. If the root cause of an issue is identified to be related to scale and performance, changes to default settings may be necessary. In this case, Rancher Support may recommend an engagement with Rancher Consulting or a partner to fine tune the settings for scale and performance.
