To enable Windows support for your EKS cluster, you should apply some configs manually. See the [Enabling Windows Support (Windows/MacOS/Linux)](https://docs.aws.amazon.com/eks/latest/userguide/windows-support.html#enable-windows-support).
Windows worker nodes requires additional cluster role (eks:kube-proxy-windows). If you are adding windows workers to existing cluster, you should apply config-map-aws-auth again.
#### Example configuration
Amazon EKS clusters must contain one or more Linux worker nodes to run core system pods that only run on Linux, such as coredns and the VPC resource controller.
1. Build AWS EKS cluster with the next workers configuration (default Linux):
```
worker_groups = [
{
name = "worker-group-linux"
instance_type = "m5.large"
platform = "linux"
asg_desired_capacity = 2
},
]
```
2. Apply commands from https://docs.aws.amazon.com/eks/latest/userguide/windows-support.html#enable-windows-support (use tab with name `Windows`)
3. Add one more worker group for Windows with required field `platform = "windows"` and update your cluster. Worker group example:
```
worker_groups = [
{
name = "worker-group-linux"
instance_type = "m5.large"
platform = "linux"
asg_desired_capacity = 2
},
{
name = "worker-group-windows"
instance_type = "m5.large"
platform = "windows"
asg_desired_capacity = 1
},
]
```
4. Wtih `kubectl get nodes` you can see cluster with mixed (Linux/Windows) nodes support.
