Antrea
A Kubernetes-native container network interface (CNI) and network security solution.
Overview
Project Antrea is an open-source project that provides a Kubernetes-native Container Network Interface (CNI) solution. It is built on Open vSwitch (OVS) to deliver high-performance networking and security services for Kubernetes clusters, including network policy enforcement.
✨ Key Features
- Kubernetes CNI plugin based on Open vSwitch
- Implementation of Kubernetes Network Policy
- Antrea-native policies for advanced security
- Network flow visibility and diagnostics tools (Antctl)
- Support for Windows and Linux worker nodes
- Encryption for inter-node traffic
🎯 Key Differentiators
- Built on the widely-used Open vSwitch (OVS)
- Strong support for hybrid clusters with both Linux and Windows nodes
- Advanced observability and troubleshooting features
Unique Value: Delivers a high-performance, secure, and observable networking layer for Kubernetes, leveraging the power and maturity of Open vSwitch.
🎯 Use Cases (4)
✅ Best For
- Used as the default CNI in VMware Tanzu Kubernetes Grid.
💡 Check With Vendor
Verify these considerations match your specific requirements:
- Environments that do not use Open vSwitch or require a non-OVS data plane.
🏆 Alternatives
Provides a more feature-complete solution than simpler CNIs like Flannel, with strong support for Windows nodes which is a key differentiator from some other advanced CNIs.
