Cilium is a leading CNCF project that has become the de-facto standard for Kubernetes networking. Among its many features is the Egress Gateway, which allows routing outgoing traffic from one or more workloads to a specific egress IP.
However, this feature lacks built-in high availability, and the egress IP must be managed externally. The Cilium HAEgress Operator (https://github.com/angeloxx/cilium-haegress-operator) addresses this limitation by providing a high-availability solution for egress traffic, ensuring continuity even in the event of node failures through dynamic virtual IP migration between nodes.
This lightning talk introduces the project, its current state, and future developments aimed at extending this standard Cilium feature.
