Documentation for version v0.9.3 is no longer actively maintained. The version you are currently viewing is a static snapshot. For up-to-date documentation, see the latest version.
This document lists the new features being considered for the future. The intention is for Antrea contributors and users to know what features could come in the near future, and to share feedback and ideas. Priorities for the project may change over time and so this roadmap is likely to evolve. A feature that is not listed now does not mean it will not be considered for Antrea. We definitely welcome suggestions and ideas from everyone about the roadmap and Antrea features. Reach us through Issues, Slack and / or Google Group!
The following features are considered for the near future:
Windows support improvements Antrea supports Windows K8s Node since version 0.7.0. However, a few features like network flow export are not supported for Windows Node yet. We will continue to add more features for Windows, and improve Antrea Agent and OVS installation on Windows Nodes.
IPv6 Pod network Support IPv6 and IPv4/IPv6 dual-stack for Pod network. Right now Antrea supports only IPv4.
Antrea NetworkPolicy Antrea has started adding support for Antrea native NetworkPolicy in addition to K8s NetworkPolicy since version 0.8.0. We already support ClusterNetworkPolicy and tiering, and will continue to add more NetworkPolicy extensions, like traffic logging, policy statistics, policy realization status, more matching criteria and actions, and external endpoints.
Network diagnostics and observability Network diagnostics and observability is one area we want to focus on. Antrea already implements some useful features on this front, including Octant UI plugin, CLI, Traceflow, network flow export and visualization, Prometheus metrics, OVS flow dumping and packet tracing. We will continue to enhance existing features and add new features to help diagnose K8s networking and NetworkPolicy implementation, and to provide good visibility into the Antrea network.
Flexible IPAM So far Antrea leverages K8s NodeIPAM for IPAM which allocates a single subnet for each K8s Node. In future, Antrea will implement its own IPAM, and support more IPAM strategies besides subnet per Node, like IP pool per Node or per Namespace.
Egress policy Egress policy is to control the egress Nodes and SNAT IPs of traffic from Pods to external network. For example, a user can request a dedicated SNAT IP per Namespace, or for a particular set of Pods or Services. This feature is very useful for services in the Node or external network to identify the source of Pod traffic based on SNAT IP and enforce specific policies on the traffic. Also check the egress policy proposal to learn more.
NFV and Telco use cases We plan to explore and provide support for NFV and Telco use cases. Will support Multus integration, Pod interfaces on SRIOV devices, and Network Service Chaining.
NetworkPolicy scale and performance tests Evaluate and benchmark the NetworkPolicy implementation performance at a large scale, including the policy computation performance of Antrea Controller and the OVS datapath performance.
OVS with DPDK or AF_XDP Leverage OVS with DPDK or AF_XDP for high performance.
