After upgrading Kubernetes (k8s), you might encounter errors such as no matches for kind "Deployment" in version "apps/v1beta1". These errors typically indicate that certain resources have become deprecated. To resolve these issues without the need to delete your Helm chart, you can follow this simple solution:
helm plugin install https://github.com/helm/helm-mapkubeapis
helm mapkubeapis <releasename>
helm upgrade <releasename>
It’s important to note that you may still need to update your Helm chart templates, especially if there have been structural changes between versions. For instance, you might observe differences in the Horizontal Pod Autoscaler (HPA) resource between versions 1.24 and 1.27.
