Versions:
Cilium CLI 0.19.2 is the command-line companion to the Cilium Container Network Interface (CNI) project, giving Kubernetes operators a single binary for installing, configuring, and troubleshooting the eBPF-powered networking and security layer that has become a de-facto standard in cloud-native infrastructure. Issued by the Cilium publisher and now in its twentieth public iteration, the tool condenses complex cluster-wide operations—such as enabling transparent encryption, collecting per-endpoint policy verdicts, or validating Hubble observability flow logs—into a concise set of sub-commands that can be scripted into CI pipelines or run ad-hoc from any administrator workstation. Typical use cases include initial deployment of Cilium on a fresh Kubernetes cluster, zero-downtime upgrades of the CNI daemon set, on-the-fly inspection of network policies to diagnose dropped packets, and generation of Sysdig-compatible capture files for forensics. Because it embeds awareness of both Kubernetes resource models and the underlying eBPF maps, the CLI can surface granular information like service-to-service latency or DNS-level security anomalies without requiring additional dashboards. The utility is catalogued under Networking Tools and is distributed as a compact, statically-linked executable for Windows, macOS, and Linux, making it equally suited for local kind clusters, on-premises bare-metal environments, and managed cloud offerings. Cilium CLI is available for free on get.nero.com, with downloads furnished through trusted Windows package sources such as winget, always delivering the latest version and supporting batch installation of multiple applications.
