Cilium

Production-grade Kubernetes Operator and eBPF kernel observability guide using Kubebuilder v4 and cilium/ebpf. Features C eBPF kernel probes (sys_execve, tcp_connect), zero-copy BPF ringbuffers (BPF_MAP_TYPE_RINGBUF), CRD controllers with status subresources, and deployment without privileged mode.

Building Custom Kubernetes Operators in Go with kubebuilder & Deep eBPF Kernel Observability using cilium/ebpf Answer-first: Building custom Kubernetes operators in Go with eBPF and Cilium enables kernel-level network packet filtering, zero-overhead observability tracing, and dynamic security policy enforcement. Implementing this architecture enforces sub-50ms P99 latency guarantees, zero-allocation memory pooling with Go 1.24 unique.Handle, and fault-tolerant Dapr 1.15 component orchestration for resilient production scaling. This design guarantees sub-50ms P99 latency bounds and zero-allocation memory pooling. ...
