## 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.

kubectl --namespace=kube-system scale deployment kube-dns --replicas=<NUM_YOU_WANT>

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
