history

Project history and usage

kubent is the Homebrew-packaged command name for Kube No Trouble, a Go CLI created to find Kubernetes objects that still use API versions scheduled for removal. It sits in the upgrade-preparation niche: operators run it before a cluster version jump so they can fix manifests, Helm releases, or last-applied kubectl state before the Kubernetes API server stops serving old versions.

Project history

The project appeared publicly as Kube No Trouble in April 2020 with release 0.1.0. Its README ties the original motivation to the Kubernetes 1.16 wave of API deprecations, and its early releases quickly added static-file scanning and collector fixes so it could work outside a live cluster as well as against kubectl and Helm-maintained resources.

Adoption history

kubent became a familiar checklist tool for Kubernetes platform teams because deprecated APIs are easy to miss in stored manifests and Helm release data. Homebrew, Scoop, Nix, and container-image distribution made it convenient to drop into upgrade runbooks and CI jobs without building from source.

How it is used

Typical use points kubent at the active kubeconfig or an explicit kubeconfig path, then asks it to collect live resources, Helm manifests, or local YAML/JSON files and report API versions that match its deprecation rules. The project also documents JSON and CI-friendly output modes for automated gates.

Why package nerds care

For package-maintainer culture, kubent is a compact example of the Kubernetes ecosystem producing tiny CLIs around version-skew pain. It matters less as a framework than as a practical binary that turns upstream API-removal policy into a package-manager-installable preflight check.

Timeline

2020-04-09: Kube No Trouble 0.1.0 was published as the initial public release of kubent.
2020-08-11: Release 0.3.0 added support for reading manifests from local files and stdin.
2024-08-30: Release 0.7.3 was listed by the repository as a later tagged release.

Related projects

kubent is closely tied to kubectl, Helm, kubeconfig files, Open Policy Agent rules, and the Kubernetes deprecated API migration guidance.
