## Manually scale kube-dns Deployment
kube-dns creates only one DNS Pod by default. If
[dns-horizontal-autoscaler](../dns-horizontal-autoscaler/)
is not enabled, you may need to manually scale kube-dns Deployment.

Do not use `kubectl edit` to modify kube-dns Deployment object if it is controlled by
[Addon Manager](../addon-manager/). Otherwise the modifications will be clobbered,
in addition the replicas count for kube-dns Deployment will be reset to 1. See
[Cluster add-ons README](../README.md) and [#36411](https://github.com/kubernetes/kubernetes/issues/36411)
