I am trying to create windows nodes in an already existing kubernetes cluster in Azure. The kubernetes cluster has two Linux nodes running on them.
I am trying to use az aks cli to create windows nodes but I don't see any option.
So can we create Linux and Windows nodes in the same kubernetes cluster? If yes, How?
Yes, this is posible, but not using the CLI\portal (at this stage). You need to use ACS engine.
You need to use this definition (adjust it to your needs):

There is a bit of a learning curve, but not that hard.
