Since Windows worker node support reached general availability in Kubernetes, Microsoft and Tigera have listened closely to feedback from the community. A big contention point of Windows container users in the Kubernetes community is: “One of the most important open source network policy tools in the market is not available for Windows.” This is limiting the adoption of Windows worker nodes for Kubernetes in environments big and small as customers cannot fulfill their policy and compliance requirements like they could address them in Linux.
Microsoft and Tigera have been working together to close several significant gaps in the Windows container networking stack. This work included enabling Direct Server Return, enhanced policy, packet logging, expanded firewall support in the Host Networking Service of Windows, multi-subnet support, and many more large and small improvements.
