### NodeSelector
You must specify node selectors on your applications so that the pods land on a node with the appropriate operating system.
For Linux pods, use the following node selector text in your manifests.
{{< output >}}
nodeSelector:
kubernetes.io/os: linux
kubernetes.io/arch: amd64
{{< /output>}}
For Windows pods, use the following node selector text in your manifests.
{{< output>}}
nodeSelector:
kubernetes.io/os: windows
kubernetes.io/arch: amd64
{{< /output>}}
{{% notice tip %}}
Our deployment file already has the proper node selectors so you won't have to add them yourself.
