Hi @ant31

I think I have finished most of the work, now I think all steps are working properly to try in a preprod environment.

I have also created:
https://github.com/pablodav/kubernetes-for-windows-quickstart

It will help to test the roles and then a good base to start working on changes before start working on a merge to kubespray directly.

Could you have a look / test it?

[pablodav]

hope #2956 could be merged, as without these changes we can't continue working on this issue. (I'm will continue working on my separate project while it is not merged)

@pablodav just tried to follow this issue. I am looking to create a hybrid cluster too, just wanted to see if you were able to push the windows support to kube-spray?

Also, what networking plugin did you end up using for windows and linux

[pablodav]

My own tracking is here: https://github.com/pablodav/kubernetes-for-windows

For now I have completed the tests only with flannel, but there are some things not 100% stabilized yet:
pablodav/kubernetes-for-windows#10

I haven't had time to test with ovn, I think kubespray doesn't support it yet.
pablodav/kubernetes-for-windows#3

calico doesn't looks to be supported at all in windows.
pablodav/kubernetes-for-windows#2

More discussion:
pablodav/kubernetes-for-windows#13

And something that I haven't looked at all yet but could be good to have before moving all this stuff to kubespray:
pablodav/kubernetes-for-windows#12

Note: the project already works and uses kubespray.

Kubernetes 1.14.1 supports Window Container as production.

IMO, it's time to support Windows Containers.
When I challenged Windows Container by manual for kubernetes, I have some of problem.
In the first, fixed these problem, next I'll create PR for this.

1. ingress nginx default-backend service has no endpoints. Then, kubelet on Windows are outputting error message continuously.

• see
  • Issue: Error while add Windows Node #4742

2. Some of ds will be scheduled on Windows Node such as

• kube-flannel-ds-amd64
• nodelocaldns
• kube-proxy

Linux ds should be fixed on Linux Node by nodeSelector.

3. flannel's network configuration should be configurable. Especiall, VNI and Port.

PR for above improvement is #4746.
