# Install ctlptl with Homebrew, Nix, zypper Making local Kubernetes clusters fun and easy to set up. Version 0.9.4 via Homebrew; verified 2026-06-04. ## Install ```sh sudo av install brew:ctlptl ``` ## Agent safety answer ctlptl manages local Kubernetes clusters and container registry wiring. - **Credential access:** Reads kubeconfig, local cluster config, and registry settings. - **Remote mutation:** Primarily local, but can affect reachable Kubernetes contexts. - **Publish/artifact risk:** Can change local cluster state used for builds and deploy tests. - **Recommended control:** Gate cluster create/delete and registry mutation commands. - **Agent-use guidance:** Allow status and config review; require approval for cluster lifecycle changes.

It uses Kubernetes-style YAML to drive local cluster products such as Docker Desktop, kind, k3d, and minikube. ### Project history The README says ctlptl was inspired by kubectl and Cluster API's clusterctl, with the idea that users declare a local cluster in YAML and let the CLI set it up. Tilt created it after helping teams debug repeated local-development environment misconfigurations. The project reached v0.1.0 in November 2020 and has continued as a 0.x tool, with official release artifacts reaching v0.9.4 in June 2026. ### Adoption history Official installation paths include Homebrew on macOS and Linux, Scoop on Windows, and go install. The README emphasizes interoperability with common local Kubernetes products rather than replacing them. ### How it is used Common commands include ctlptl get, create cluster, apply -f cluster.yaml, and delete -f cluster.yaml. Typical package use is in developer-workstation setup scripts and CI-friendly local-cluster recipes where a registry, CPU limits, Kubernetes version, or Docker Desktop setting needs to be repeatable. ### Why package nerds care ctlptl is packaging glue for the local Kubernetes stack: it wraps existing cluster implementations, exposes declarative YAML, and provides package-manager-friendly binaries for developers who want reproducible local infrastructure without maintaining bespoke shell scripts. ### Timeline - 2020: v0.1.0 release published. - 2020: Early releases added declarative local-cluster workflows around kind, k3d, minikube, and Docker Desktop. - 2026: v0.9.4 release published. ### Related projects - ctlptl is explicitly related to kubectl, Cluster API's clusterctl, kind, k3d, minikube, Docker Desktop, and Tilt's local-development tooling. ### Sources - - - ## Security Notes infrastructure mutation or orchestration signal. - **Geiger risk:** orange / medium - infrastructure mutation or orchestration signal ## Configuration and credential file locations These source-backed paths show where this package keeps local settings or durable credentials.
