The following must be installed locally before you can install :
Application | Download from | Comments |

Horizontal Pod Autoscaler | A metrics server is required when it comes to scaling. If you are planning to use the Horizontal Pod Autoscaler with custom metrics scaling, you will need to set up a Prometheus Adapter (see Setting up Prometheus). For smaller and less complicated scaling such as using CPU based scaling, you can utilize a smaller metrics server such as: https://github.com/kubernetes-sigs/metrics-server. |
