An application can sometimes require diverse components that span technology stacks. There may be a depency on a legacy component built for Windows which may not be suitable for deployment to Linux. The good news is it may still be suitable for deployment to Kubernetes. With a Windows node in your OpenShift cluster you can deploy cross-platform applications that can simultaneously leverage the strengths of Linux and Windows.
The Windows Machine Config Operator builds and configures Windows machines to act as nodes in an OpenShift cluster enabling cross platform workloads. This post will demonstrate the addition of a Windows node to an existing cluster and explore the integration of Windows and Kubernetes.
Adding support for Windows nodes in your OpenShift cluster is a day 2 operation that requires preparation at install time. It is important to accommodate the hybrid networking requirements for Windows Kubernetes nodes. Azure specific tasks and gotchas are highlighted in this part 1 of 3 while laying the groundwork applicable to deploying OpenShift on any provider in preparation for managing Windows containers.
