history

Project history and usage

Kor is a Kubernetes cleanup CLI focused on finding unused or orphaned resources. Its history is short but package-relevant because it packages a common cluster-hygiene job as a small Go command, Helm deployment, Docker image, and kubectl plugin.

Project history

The GitHub repository was created on 2023-07-05. The README describes Kor as a Kubernetes Orphaned Resources Finder and lists Kubernetes object types such as ConfigMaps, Secrets, Services, PVCs, Ingresses, CRDs, PVs, Pods, Jobs, ReplicaSets, DaemonSets, StorageClasses, NetworkPolicies, and VolumeAttachments.

Release metadata shows early v0.1.x releases in July and August 2023, beginning with v0.1.2 on 2023-07-23. The project later added chart-oriented releases and documentation for running Kor as a cron job or deployment with Prometheus metrics.

Adoption history

Kor's adoption signal is mostly Kubernetes-operator packaging rather than a long institutional history. The README documents Homebrew, Go install, Docker, Krew, and Helm installation paths, which made the tool available in the normal places Kubernetes users look for cleanup utilities.

GitHub repository metadata observed on 2026-07-01 reported 1,802 stars and 148 forks, enough to indicate real Kubernetes community interest despite the project's relatively recent start.

How it is used

Users run Kor against a cluster to list resources that appear unused, or deploy it in-cluster for scheduled scans and metrics. The README also documents labels for ignoring resources or forcing cleanup decisions, which is important because Kubernetes cleanup can be risky when ownership is unclear.

Why package nerds care

Kor is package-nerd interesting because it is a narrow, single-purpose Kubernetes hygiene tool that shows how operational chores become installable CLIs.

Its distribution across Homebrew, Krew, Helm, Docker, Nix, and zypper is the real story: each packaging channel maps to a different operator workflow, from laptop audit to in-cluster scheduled scan.
