+# Adding Windows Worker nodes to an openCenter Kubernetes cluster
+
+## Requirements
+* A working openCenter cluster with at least 1 linux worker node.
+* Windows servers added to the oc_windows_workers group in the ansible inventory. Must be accessible via `SSH`. Yes SSH.
+* 
+
+
+The main.tf file will require additional local variables and variables passed to the openTofu modules.
+
+| Option | Default | Type | Description |
+| :------- | :------: | :-------: | -------: |
+| image_id_windows | "" | string | Glance image ID for Windows Server |
+| flavor_worker_windows | "" | string | Openstack Flavor name |
+| windows_user | "Administrator" | string | Admin user for Windows Server |
+| windows_admin_password | "" | String | Password for Admin user of Windows Server|
+| worker_node_bfv_size_windows | 0 | number | Volume Size of root disk for Windows Server |
+| worker_node_bfv_type_windows | "local" |  string | Volume type. Can be either "local" or "volume" |
+
+
+The Openstack Nova module needs to get the values passed
+
+```
+
+source = "github.com/rackerlabs/openCenter-gitops-base.git//iac/cloud/openstack/openstack-nova?ref=main" {
+    ...
+    size_worker_windows = {
+        count  = local.worker_count_windows
+        flavor = local.flavor_worker_windows
+    }
+    windows_admin_password  = local.windows_admin_password
+    windows_user  = local.windows_user
+    worker_node_bfv_type_windows = local.worker_node_bfv_type_windows
+    worker_node_bfv_size_windows = local.worker_node_bfv_size_windows
+}
+```
+
+There is an ansible collection in `github.com/rackerlabs/opencenter-windows.git` that can be used to configure the windows nodes as workers and have them join the cluster.
+
+Set the collections path to the local cluster inventory file.
+
+```bash
+
+source venv/bin/activate
+export ANSIBLE_COLLECTIONS_PATHS=${PWD}/inventory/
+export ANSIBLE_INVENTORY=${PWD}/inventory/inventory.yaml
+
+ ```
+
+requirements.yml
+
+```yaml
+---
+collections:
+  - name: https://github.com/rackerlabs/opencenter-windows.git
+    type: git
+    version: main
+```
+
+Install the collection
+
+```bash
+ansible-galaxy collection install -r requirements.yml
+```
+
+windows-worker.yaml
+
+```yaml
+- name: Join Windows to Kubernetes cluster
+  hosts: oc_windows_nodes
+  gather_facts: yes
+  collections:
+    - rackerlabs.opencenter_windows_workers
+  tasks:
+    - name: Gather variables for each operating system
+      ansible.builtin.import_role:
+        name: kubespray/roles/kubespray_defaults
+
+    - name: Setup win-containerd
+      ansible.builtin.include_role:
+        name: win-containerd
+
+    - name: Setup win-kubeadm
+      ansible.builtin.include_role:
+        name: win-kubeadm
+```
+
+`ansible-playbook windows-workers.yaml`
+
+## Post Join steps
+Taint the nodes to avoid confusing the scheduler
+`kubectl taint node mig-dev-win0 node.kubernetes.io/os=windows:NoSchedule`
+
+
+Once Calico has been deployed via the Tigera Operator the IPAM Config must get patched.
+
+`kubectl patch ipamconfigurations default --type merge --patch='{"spec": {"strictAffinity": true}}'`
