## プロジェクトの歴史と使われ方

kbld is a Carvel CLI for Kubernetes and YAML workflows that builds, pushes, resolves, locks, packages, and relocates container image references.

### プロジェクトの歴史

The kbld repository began in April 2019. Its README and Carvel site describe a tool that delegates image building to mature tools such as Docker and Buildpacks pack, then rewrites YAML configuration to immutable digest references.

kbld grew as part of the k14s/Carvel family rather than as a standalone monolith. Carvel documentation presents ytt, kbld, and kapp as composable tools: ytt structures and overlays YAML, kbld handles images, and kapp deploys and diffs Kubernetes resources.

### 採用の歴史

Carvel's public materials describe the suite as born from frustration with monolithic Kubernetes deployment tools and built around Unix-style composition. kbld's adoption follows that pattern: it appears in Homebrew, Nix, and Carvel install flows as one small command in a larger Kubernetes delivery toolchain.

### 使われ方

Typical kbld usage pipes or reads YAML, finds image references, builds or resolves them, and emits YAML with digest-pinned images. Its docs also cover lock files, registry pushes, packaging images into tarballs, and relocation between registries.

### パッケージ好きにとっての重要性

kbld is package-nerd interesting because it makes image immutability a CLI transformation step. Instead of hiding build metadata in a platform service, it keeps the artifact graph visible in YAML and lock files that can be piped into other tools.

### タイムライン

- 2019-04-19: Repository initialized
- 2019: k14s tools including kbld were released as composable Kubernetes workflow tools
- 2020-08: k14s was rebranded as Carvel
- 2022-10: VMware announced Carvel's move into the CNCF Sandbox
- 2026-06-17: v0.49.1 release appeared in the GitHub release list

### Related projects

- kbld is closely related to Carvel ytt, kapp, imgpkg, vendir, kapp-controller, Docker, Buildpacks pack, Kubernetes manifests, Helm, and kustomize.
