Deploying to Hybrid Linux/Winodws K8s Clusters
Installing the Dapr Control Plane
If you are installing using the Dapr CLI or via helm chart, you can simply follow our normal deployment procedures: Installing Dapr on a Kubernetes cluster
Affinity will be automatically set for kubernetes.io/os=linux. If you need to override linux to another value, you can do so by setting:
helm install dapr dapr/dapr --set global.daprControlPlaneOs=YOUR_OS
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
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.
Note: Windows support for dapr applications is in progress. Please see: dapr/dapr#842.
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.
spec:
nodeSelector:
kubernetes.io/os: linux
Kubernetes also supports much more advanced configuration via node affinity. See https://kubernetes.io/docs/concepts/scheduling-eviction/assign-pod-node/ for more examples.
