プロジェクトの歴史

The cilium/cilium-cli repository was created in December 2020. Its early public releases began with v0.1 in February 2021, aligning with the project's move toward a dedicated CLI for cluster installation, status checks, Hubble enablement, connectivity testing, ClusterMesh, and related operations.

The CLI is maintained as a separate Go repository from the main Cilium datapath and control-plane repository, but its README and Cilium documentation present it as the standard quick-install path for Cilium users.

採用の歴史

Cilium's official quick-install documentation instructs users to install the Cilium CLI before installing Cilium into a Kubernetes cluster. That placement makes the CLI a front door for new Cilium deployments rather than only an optional helper.

The input records packages across Homebrew, Alpine, Nix, Arch, winget, and zypper. Homebrew's formula API currently reports more than one thousand 30-day install-on-request events, which is strong package-manager adoption for a specialized Kubernetes networking CLI.

使われ方

Common documented commands include cilium install, cilium status, cilium hubble enable, cilium connectivity test, cilium connectivity perf, and ClusterMesh setup. The README also lists supported environments such as minikube, kind, EKS, GKE, AKS BYOCNI, k3s, and self-managed clusters.

パッケージ好きにとっての重要性

For package maintainers, cilium-cli is a modern cloud-native operations binary with frequent releases, official multi-OS binary artifacts, and compatibility tracking against Cilium versions. It is also a good example of package managers distributing the operational CLI separately from the Kubernetes workloads it manages.
