Starting with v2, cmctl is versioned separately in its own repository. The standalone GitHub repository was created in January 2024 and its release stream begins with v2.0.0 prereleases and v2.0.0 in March 2024. ### Adoption history cmctl follows cert-manager into Kubernetes operator workflows: it can inspect certificates, approve or deny CertificateRequests, check cert-manager health, and assist with installation, upgrade, and uninstall tasks. The official README documents Homebrew, Go install, manual release binaries, shell completion, and distributed third-party packages. ### How it is used Official docs describe `cmctl` as a tool for managing cert-manager resources inside a cluster. Typical usage is operational rather than general-purpose: checking API health, inspecting Certificate and CertificateRequest objects, approving or denying requests, and using experimental `cmctl x` subcommands around cert-manager installation and lifecycle tasks. ### Why package nerds care cmctl matters to package nerds because it is a Kubernetes ecosystem CLI with multiple distribution channels: Homebrew on macOS/Linux, Go install, GitHub release binaries, shell completions, and distro packages. Its separate v2 versioning is a packaging boundary: the CLI can now release independently of the controller it manages. ### Timeline - 2024-01: Standalone cmctl repository created. - 2024-03: v2.0.0 released, establishing the separately versioned CLI line. - 2024-06: v2.1.0 released. - 2025: v2.2.0 and later releases continue the standalone series. ### Related projects - cmctl is directly related to cert-manager and Kubernetes. The README also documents an alternate installation name, `kubectl-cert_manager`, for use as a kubectl plugin-style command. ### Sources - - - - ## Security Notes narrow executable package without higher-risk signals. -
