什么是Cloud Native Buildpacks（CNBs）？

CNBs是用于将应用源代码转换为可运行OCI镜像的模块化组件。

通常，Buildpacks提供了比Dockerfile更高层次的应用构建抽象。Cloud Native Buildpacks是由Pivotal和Heroku发起的项目，是Cloud Native Sandbox的成员。该项目通过平台与Buildpack之间的契约统一了Buildpack生态系统，采用现代容器标准，特别是OCI镜像格式。

这些镜像（cloudfoundry/cnb）是什么？

这些镜像称为构建器（builders），包含内部操作系统镜像（详见下文差异部分）、应用生命周期可执行文件以及Cloud Native Buildpacks集合，均按照https://github.com/buildpack/spec%E6%9E%84%E5%BB%BA%E3%80%82%E5%AE%83%E4%BB%AC%E7%94%B1https://github.com/buildpack/packhttps://github.com/buildpack/pack#working-with-builders-using-create-builder%E5%B9%B6https://github.com/buildpack/pack#example-building-using-the-default-builder-image%E3%80%82

不同标签代表底层文件系统的差异，支持不同操作系统：

• https://github.com/cloudfoundry/stacks/blob/master/bionic/base/build/Dockerfile → 基于Ubuntu 18.04（Bionic Beaver）的最小镜像，添加了一些包（称为https://github.com/buildpack/spec/blob/master/platform.md#mixins%EF%BC%89%E2%80%94%E2%80%94%E7%89%B9%E5%88%AB%E6%98%AF%60git%60%E5%92%8C%60build-essentials%60%EF%BC%88%E4%B8%BA%E6%88%90%E5%8A%9F%E8%BF%90%E8%A1%8C%60go%60%E5%BA%94%E7%94%A8%E8%80%8C%E6%B7%BB%E5%8A%A0%EF%BC%89%E3%80%82
• https://github.com/cloudfoundry/cflinuxfs3 → 基于Ubuntu 18.04（Bionic Beaver）的镜像，补充了https://github.com/cloudfoundry/cflinuxfs3/blob/master/receipt.cflinuxfs3.x86_64%E3%80%82
• https://github.com/cloudfoundry/stacks/tree/master/tiny/base/run → 最小构建镜像（与base相同），带有基于Ubuntu 18.04（Bionic Beaver）的极小、类distroless运行镜像。

注意：目前，运行python、php、httpd或nginx应用时，cflinuxfs3是唯一选项。

支持的语言生态系统

每个语言生态系统由特定语言的CNB与构建系统工具的某种组合构成。
