Check my scripts at https://github.com/bplasmeijer/Sitecore-Symposium-2020-Containers-AKS and check 2.CreateAKS.ps1, do you have a windows node on your cluster?
az aks create --resource-group MyResourceGroup --name sc10aks --node-count 1 --enable-addons monitoring --generate-ssh-keys does not create a windows node.
If you are looking to deploy a Sitecore 10 Dev/Non-Prod Instance you might give my "all in one" powershell deployment script a try. Its targeted for XM, I will be creating one for XP as well as time allows, or you could use what I have here as a template and just do it yourself.
