# Deploying to Hybrid Linux/Winodws K8s Clusters
# Deploy to hybrid Linux/Windows Kubernetes clusters
If you would like to deploy dapr to a Kubernetes cluster that contains both Windows and Linux nodes, you can do so, but there are known limitiations. All dapr control plane components must be run exclusively on Linux enabled nodes. The same is currently true for all Dapr applications. Thus when deploying to hybrid Kubernetes clusters you will need to ensure that Kubernetes knows to place your application containers exclusively on Linux enabled nodes.
> **Note:** Windows container support for Dapr applications is in progress. Please see: [dapr/dapr#842](https://github.com/dapr/dapr/issues/842).
## Installing the Dapr Control Plane

Dapr control plane container images are only provided for Linux, so you shouldn't need to do this unless you really know what you are doing.
## Installing Dapr Apps
## Installing Dapr applications
The Dapr sidecar container is currently Linux only. For this reason, if you are writing a Dapr application, you must run it in a Linux container.

When deploying to a hybrid cluster, you must configure your apps to be deployed to only Linux available nodes. One of the simplest ways to do this is to add kubernetes.io/os=linux to your app's nodeSelector.

Kubernetes also supports much more advanced configuration via node affinity.
