Maciek Pytel 9831623810 Set different hostname label for upcoming nodes 
Function copying template node to use for upcoming nodes was
not chaning hostname label, meaning that features relying on
this label (ex. pod antiaffinity on hostname topology) would
treat all upcoming nodes as a single node.
This resulted in triggering too many scale-ups for pods
using such features. Analogous function in binpacking didn't
have the same bug (but it didn't set unique UID or pod names).
I extracted the functionality to a util function used in both
places to avoid the two functions getting out of sync again.

Kubernetes Autoscaler

Build Status GoDoc Widget

This repository contains autoscaling-related components for Kubernetes.

What's inside

Cluster Autoscaler - a component that automatically adjusts the size of a Kubernetes Cluster so that all pods have a place to run and there are no unneeded nodes. Works with GCP, AWS and Azure. Version 1.0 (GA) was released with kubernetes 1.8.

Vertical Pod Autoscaler - a set of components that automatically adjust the amount of CPU and memory requested by pods running in the Kubernetes Cluster. Current state - beta.

Addon Resizer - a simplified version of vertical pod autoscaler that modifies resource requests of a deployment based on the number of nodes in the Kubernetes Cluster. Current state - beta.

Charts - Supported Helm charts for components above.
