Cilium Has a Free API: eBPF-Powered Networking and Security for Kubernetes

Cilium is an open-source networking, observability, and security solution for Kubernetes powered by eBPF. It provides high-performance networking, transparent encryption, and advanced network policies. What Is Cilium? Cilium is a CNCF graduated project that uses eBPF to provide networking, security, and observability at the Linux kernel level. It replaces kube-proxy and traditional CNI plugins with eBPF programs that run directly in the kernel. Key Features: eBPF-based dataplane (no iptables) Network policies (L3/L4/L7) Transparent encryption (WireGuard/IPsec) Hubble observability platform Service mesh (sidecar-free) Multi-cluster connectivity (ClusterMesh) BGP support Bandwidth management Installation # Install Cilium CLI curl -L --remote-name-all https://github.com/cilium/cilium-cli/releases/latest/download/cilium-linux-amd64.tar.gz tar xzf cilium-linux-amd64.tar.gz sudo mv cilium /usr/local/bin/ # Install Cilium on cluster cilium install --version 1.16.0 # Enable Hubble (observabili
