Hi, We have rancher setup (2.69), and we have created multiple EC2 provider clusters (RKE2). Now, we want to add windows worker nodes in existing ec2 provider clusters. Kindly advise if it is possible. Your support will be highly appreciated. Regards!

Windows? :melting_face:

yes, it is already support in customer clusters.

Why your are not using Ubuntu or Amazon Linux instead?

windows based containers will run on windows worker nodes only

And why you are not using linux based containers instead?

depends on the application needs

You mean you have applications that only are able to run on Windows Servers? and not Linux/Ubuntu?

yes

Your cluster already have worker nodes running not Windows Server Os?

yes, cluster has master nodes and worker nodes .. all linux ..

Ok so, you can do it. You just need to build your EC2 template with Windows Server and when you add some new pool node you should pick de AMI ID

are you sure about this?

Never tried but according Rancher it’s possible

but did they mention if windows worker node can be added?

hhmm..so according to the Rancher documentation, the only way to create a Kubernetes cluster with both Windows Server and Ubuntu nodes is to create a separate Kubernetes cluster for the Windows Server nodes and then set up a separate cluster for the Ubuntu nodes. Detailed information on how to create heterogeneous Kubernetes clusters with Rancher can be found at this link: https://ranchermanager.docs.rancher.com/v2.5/pages-for-subheaders/use-windows-clusters

you can have 1 custom cluster with both linux and windows worker nodes mixed.
