It operates at Layer 3/4 to provide networking and\nsecurity services for a Kubernetes cluster, leveraging\n[Open vSwitch](https://www.openvswitch.org/) as the networking data plane.\n\n\u003cp align=\"center\"\u003e\n\u003cimg src=\"docs/assets/antrea_overview.svg.png\" width=\"500\" alt=\"Antrea Overview\"\u003e\n\u003c/p\u003e\n\nOpen vSwitch is a widely adopted high-performance programmable virtual\nswitch; Antrea leverages it to implement Pod networking and security features.\nFor instance, Open vSwitch enables Antrea to implement Kubernetes\nNetwork Policies in a very efficient manner.\n\n## Prerequisites\n\nAntrea has been tested with Kubernetes clusters running version 1.23 or later.\n\n* `NodeIPAMController` must be enabled in the Kubernetes cluster.\\\n  When deploying a cluster with kubeadm the `--pod-network-cidr \u003ccidr\u003e`\n  option must be specified.\n  Alternately, NodeIPAM feature of Antrea Controller should be enabled and\n  configured.\n* Open vSwitch kernel module must be present on every Kubernetes node.\n\n## Getting Started\n\nGetting started with Antrea is very simple, and takes only a few minutes.\nSee how it's done in the [Getting started](docs/getting-started.md) document.\n\n## Contributing\n\nThe Antrea community welcomes new contributors.

Refer to the [Antrea Multi-cluster documentation](docs/multicluster/user-guide.md)\n  to get started.\n* **Troubleshooting and monitoring tools**: Antrea comes with CLI and UI tools\n  which provide visibility and diagnostics capabilities (packet tracing, policy\n  analysis, flow inspection). It exposes Prometheus metrics and supports\n  exporting network flow information to collectors and analyzers.\n* **Network observability and analytics**: Antrea + [Theia](https://github.com/antrea-io/theia)\n  enable fine-grained visibility into the communication among Kubernetes\n  workloads. Theia provides visualization for Antrea network flows in Grafana\n  dashboards, and recommends Network Policies to secure the workloads.\n* **Network Policies for virtual machines**: Antrea-native policies can be\n  enforced on non-Kubernetes Nodes including VMs and baremetal servers. Project\n  [Nephe](https://github.com/antrea-io/nephe) implements security policies for\n  VMs across clouds, leveraging Antrea-native policies.\n* **Encryption**: Encryption of inter-Node Pod traffic with IPsec or WireGuard\n  tunnels.\n* **Easy deployment**: Antrea is deployed by applying a single YAML manifest\n  file.\n\nTo explore more Antrea features and their usage, check the [Getting started](docs/getting-started.md#features)\ndocument and user guides in the [Antrea documentation folder](docs/). Refer to\nthe [Changelogs](CHANGELOG/README.md) for a detailed list of features\nintroduced for each version release.\n\n## Adopters\n\nFor a list of Antrea Adopters, please refer to [ADOPTERS.md](ADOPTERS.md).\n\n## Roadmap\n\nWe are adding features very quickly to Antrea. Check out the list of features we\nare considering on our [Roadmap](ROADMAP.md) page.
