OVN-Kubernetes v1.0.0

[tssurya]

v1.0.0

📢 We are happy to announce the release of OVN-Kubernetes v1.0.0, our first major release. 🎉 🎊 🎆 🎇💥
This version of OVN-Kubernetes uses:
☸️ Kubernetes v1.29.2
🔁 OVN ovn-24.03.2-5.fc39.x86_64
🔄 OVS openvswitch-3.2.2-1.fc39.x86_64

Summary of important changes for this release

This release includes many exciting features that end-users can leverage:

🔀 Interconnect mode of deploying OVN-Kubernetes with a distributed database architecture - this makes OVN-Kubernetes more scalable, performant and secure

🌐 EgressIPs which allows users to send northbound traffic from the selected pods using "the special pool of user configured egressIPs"

🔐 EgressFirewall which allows users to impose fine grained traffic security rules on northbound traffic leaving from the selected pods in the cluster

🎯 EgressQoS which performs DSCP markings on pods that can be leveraged to perform traffic shaping and policing

🎖️ EgressService which allows users to send northbound traffic from the selected pods using the load balancer service ingress VIP (reverse of service ingress)

🌐 Multiple External Gateways which allows pods to send egress traffic outside the cluster via a set of defined egress gateway pods

🔐 AdminNetworkPolicy which allows admins to create cluster-wide security policies that limit network traffic based on the principle of least privilege and zero trust

💫 Multihoming which allows plugging multiple interfaces to a Pod with each of the secondary interfaces managed by OVN-Kubernetes CNI

🔐 MultiNetworkPolicy provides an ability to define network policies on the secondary interfaces of the pods

📥 HardwareAcceleration provides an ability to achieve line speed Kubernetes Pod networking - transmit/receive, network policy, NATing, Load Balancers, and so on

🏗️ Kubevirt VM Live Migration allows kubevirt virtual machines to be live migrated while keeping the established TCP connections alive, and preserving the VM IP configuration.

🌉 Hybrid Overlay provides the ability to run both linux and windows nodes on your same cluster

🚇 Tunneling over Multiple NICS provides an ability to tunnel traffic from K8s Pods over different NICs on the same host.

Binaries Released

• ovnkube which is our main single all-in-one binary executable used to launch the ovnkube control plane and data plane pods in a kubernetes deployment
• ovn-k8s-cni-overlay is the cni executable to be placed in /opt/cni/bin (or another directory in which kubernetes will look for the plugin) so that it can be invoked for each pod event by kubernetes
• hybrid-overlay-node is a node controller to integrate disparate networks with VXLAN tunnels
• ovn-kube-util contains the Utils for ovn-kubernetes
• ovndbchecker runs ovn db checker to ensure raft membership and db health on default deployment modes
• ovnkube-trace is the binary that contains ovnkube-trace which is an abstraction used to invoke OVN/OVS packet tracing utils
• ovnkube-identity is the executable that is invoked to run ovn-kubernetes identity manager, which includes the admission webhook and the CertificateSigningRequest approver
