Is it possible to run both Linux and Windows nodes within the same cluster on Azure Service Fabric?
No, that is currently not possible.

I have worked with minikube as a single node Kubernetes cluster on windows to learn it. Now, I need to figure if it is possible to create a multi-node Kubernetes cluster on windows using other Vms..
I need to figure also the best production scenario for windows( to automate the Vms creation, configuration ), as alternative like (vagrant / ansible) on Linux.
Yes, it's possible. Feel free to create several VMs manually in the tool of your choice and network them together.
Vagrant and Ansible (Pull) work fine on Windows as well, where Ansible runs in the guest OS.
Or you can run Ansible and/or Docker from WSL.
FWIW, other than for learning purposes, there is little benefit of simulating a cluster of Kubernetes/Openshift or similar platform on all single machine. The same resources should work whether you have one node or many
What i want do is deployment of multiple container application in...
In RHEL os
RedHat Supportable product (if possible)
In single node K8S cluster (Bare metal machine)
So I found several way but I concerned about..
minikube, minishift, OKD, CodeReady Container
First, they run in VM but what I want is run in HOST.
Second, their doc said they are not for production environment.
So, Is there any PaaS for single-node cluster as production environment?
Docker, Docker-compose
Deployment target OS should maybe RHEL8. I guess it is not good idea to use docker because RedHat product is moving away from docker. Even in RHEL8 repository, there is no docker rpm for el8 yet.
My question is
Is there any PaaS for single-node cluster as production environment?
If not exist, docker-compose is best?
It was already mentioned, you should not use single node setup in production environment.
You should not do that because, if your servers drops you have service offline. There is nothing to switch to, nothing that might continue the process that was being worked on.
If you still want to setup a single node Kubernetes cluster you can do that using kubeadm. I think this would be closest to production grade as you can get.
Other then that as an alternative you can play with Installing Kubernetes with Minikube or Install a local Kubernetes with MicroK8s.
It's up to you which one you will choose but you need to remember this should not be running as a production, this should be a lab or a test environment which if works as expected will be migrated into few node production grade cluster.
As for PaaS as a single node there is Dokku.
Docker powered mini-Heroku. The smallest PaaS implementation you've ever seen.
And if you would consider using a cloud for PaaS, you can choose from AWS Cloud9, Azure App Service or Google App Engine.
Single node cluster is not recommended for production applications. You need scalability, high availability, fault tolerance for production apps. You must have more than one node to have these features.
Is there a possibility to have mixed windows and linux work nodes on Azure Service Fabric, or the cluster must be homogeneous?
No this is still not possible.
Was also asked before as well:
Service Fabric: Is it possible to run both Linux and Windows nodes
I have tried creating Kubernetes cluster but all the nodes are linux based OS(Container-Optimized OS (cos) (default) and Ubuntu). I have windows based image stored on docker Hub I need to deploy this app to kubernetes cluster. I am using https://console.cloud.google.com/kubernetes/ to create cluster.
While creating nodes, in setting there are only two options: Container-Optimized OS (cos) (default) and Ubuntu.
Windows is not supported by Google Kubernetes. There is a feature request that you can track: Feature request : Support for Windows Server Containers in GKE
You can launch your own Google Compute VM and run Windows containers. This article provides more information.
I don't think you can run Windows nodes in GKE, even though Kubernetes itself supports Windows nodes (https://kubernetes.io/docs/getting-started-guides/windows/).
In my opinion, the other options you have are:
Run an on-prem Kubernetes cluster with your Windows licenses (the control plane would still run with Linux, only the nodes would be Windows based)
Use GCE instead of GKE to run your containers: https://cloud.google.com/compute/docs/containers/ and https://cloud.google.com/blog/products/gcp/how-to-run-windows-containers-on-compute-engine
Hope that helps!
I have MiniKube running on my Windows 10 machine. I would like to add an additional node to the cluster.
I have a Centos VM running on a different host that has k8s installed. How to I get the kubectrl join command to run on the VM from the master node running on my Windows machine?
Do I need to install an overlay network on the MiniKube VM? Or is one already installed?
Minikube is officially single-node at the moment. There's a discussion about this limitation at https://github.com/kubernetes/minikube/issues/94 But it seems people have found ways to do it with VirtualBox and there are other ways to run a multi-node cluster locally. Otherwise I'd suggest creating a cluster with one of the cloud providers (e.g. GKE).
