Create a windows kubernetes worker node

Kubernetes control planes are set to only run on Linux distributions, but your organization runs some of its docker images using a windows host container. Are you out of luck? NO! Read on to find out exactly how to set up a windows worker node in Kubernetes

Install Windows daemons for linux

The control plane, which is running under a Linux host, will need a windows daemon for linux installed. To do so you must do the following:

1. curl -L https://github.com/kubernetes-sigs/sig-windows-tools/releases/latest/download/kube-proxy.yml | sed 's/VERSION/v1.20.0/g' | kubectl apply -f -

2. kubectl apply -f https://github.com/kubernetes-sigs/sig-windows-tools/releases/latest/download/flannel-overlay.yml

Install Windows Worker Node

The worker node that is running docker containers using a Windows Host will need to be running Windows Server 2019 or better.
