SOLVED: Error UPGRADE FAILED unable to build kubernetes objects from current release manifest
problem
We has a service that had not been deployed in a while and since then we have upgraded our since then we upgraded our Kubernetes cluster to version 1.3.0. This upgrade included the deprecation of the autoscaling/v2beta2 API (deprecated 1.2.6), which was used by the service's HorizontalPodAutoscaler (HPA). Some how the object was deleted and attempting to upgrade the application's Helm chart resulted in the following error:
Error: UPGRADE FAILED: unable to build kubernetes objects from current release manifest: resource mapping not found for name: "" namespace: "" from "": no matches for kind "HorizontalPodAutoscaler" in version "autoscaling/v2beta2"solution
This error indicates that Helm was unable to retrieve the current release manifest because the HorizontalPodAutoscaler (HPA) object was missing. Furthermore, our Kubernetes version (1.3.0) no longer supports the autoscaling/v2beta2 API version required by the missing HPA. The resolution involved updating the API versions within our release manifest using helm-mapkubeapis
