This topic introduces kube-flannel-ds-windows and describes the usage notes and release notes for kube-flannel-ds-windows.

Introduction

kube-flannel-ds-windows is a container network plug-in used by managed Kubernetes clusters. kube-flannel-ds-windows is used to set up a l2bridge network to connect Windows containers.

Usage notes

If you choose Flannel as the network plug-in when you create a managed Kubernetes cluster, kube-flannel-ds-windows is automatically deployed as a DaemonSet in the cluster. kube-flannel-ds-windows is dependent on the privileged proxy processes on Windows nodes. kube-flannel-ds-windows can be deployed only on Windows nodes that are added with the windows.alibabacloud.com/deployment-topology=2.0 label. By default, the windows.alibabacloud.com/deployment-topology=2.0 label is added to a Windows node when the node is created.

If your cluster does not contain Windows nodes or the Windows nodes in your cluster are not added with the windows.alibabacloud.com/deployment-topology=2.0 label, no replicated pods are provisioned for kube-flannel-ds-windows.

If a Windows node is added with the windows.alibabacloud.com/deployment-topology=2.0 label but no replicated pods are provisioned for kube-flannel-ds-windows, you must redeploy kube-flannel-cfg-windows and kube-flannel-ds-windows.
