## プロジェクトの歴史と使われ方
Krew is the Kubernetes SIG CLI package manager for kubectl plugins. It is package-nerd significant because it brings a Homebrew-like install, search, update, and index model inside the kubectl plugin ecosystem.
### プロジェクトの歴史
The krew repository was created on 2018-07-12, and the first v0.1.0-alpha.1 release was published on 2018-07-30. The project README describes Krew as a package manager for kubectl plugins that helps users discover, install, and manage plugins, and helps plugin developers package and distribute plugins across platforms.
Krew exists because kubectl plugins are ordinary executables named with the kubectl- prefix and found on PATH. Kubernetes documentation describes that plugin mechanism and identifies Krew as a SIG CLI-maintained way to discover and install community plugins.
### 採用の歴史
Krew became the de facto index-driven distribution channel for kubectl plugins because it solved discovery and update management for a plugin system that otherwise only specifies executable naming. The Kubernetes blog recommended Krew in 2020 for plugin installation experience and discoverability.
The Krew README says that more than 200 kubectl plugins were available through Krew in the documentation state used for this 2026-07-01 batch, showing a mature plugin catalog rather than a single-tool installer.
### 使われ方
Users install Krew as the kubectl-krew plugin, add its bin directory to PATH, and then run commands such as kubectl krew search, kubectl krew install, kubectl krew list, kubectl krew update, and kubectl krew upgrade.
Plugin authors package manifests in the krew-index repository so their kubectl plugins can be discovered and installed consistently on Linux, macOS, and Windows.
### パッケージ好きにとっての重要性
Krew is a package manager distributed as a plugin for the tool whose plugins it manages, which makes it a neat recursive packaging artifact. It also codifies an index and lifecycle around kubectl plugins without changing kubectl's intentionally simple PATH-based plugin contract.
