Cilium is an open source, cloud native solution for providing, securing, and observing network connectivity between workloads, fueled by the revolutionary Kernel technology eBPF

Cilium is an open source project to provide networking, security, and observability for cloud native environments such as Kubernetes clusters and other container orchestration platforms.

Cilium IPv6 Networking and Observability. Learn how simple IPv6 can be installed and operated with Cilium and Hubble. With Kubernetes’ IPv6 support improving in recent releases and Dual Stack Generally Available in Kubernetes 1.23, it’s time to learn about IPv6 on Kubernetes.

Cilium is an open source software for transparently securing the network connectivity between application services deployed using Linux container management platforms like Docker and Kubernetes. At the foundation of Cilium is a new Linux kernel technology called eBPF, which enables the dynamic insertion of powerful security visibility and ...

Cilium Service Mesh redefines traditional service mesh frameworks by integrating the mesh layer directly into the kernel using eBPF, thus eliminating the need for sidecar proxies. It manages connectivity at both the networking and application protocol layers, handling protocols like IP, TCP, UDP, HTTP, Kafka, gRPC, and DNS with greater efficiency.

Make Cilium take ownership over the /etc/cni/net.d directory on the node, renaming all non-Cilium CNI configurations to *.cilium_bak. This ensures no Pods can be scheduled using other CNI plugins during Cilium agent downtime.

Feb 21, 2025 · The Cilium community is buzzing to reunite again this April in London for KubeCon + CloudNativeCon EU and CiliumCon. As one of the most widely adopted open source projects in the cloud native ecosystem, Cilium continues to revolutionize networking, security, and …

In this lab, you will learn how you can use Cilium to deploy Ingress resources to dynamically configure the Envoy proxy provided with the Cilium agent. And all of the above without any Envoy sidecar injection into your pods!

Cilium uses the standard Kubernetes Ingress resource definition, with an ingressClassName of cilium. This can be used for path-based routing and for TLS termination. For backwards compatibility, the kubernetes.io/ingress.class annotation with value of cilium is also supported.
