用 Juju 搭建 Kubernetes
Ubuntu 16.04 introduced the Canonical Distribution of Kubernetes , a pure upstream distribution of Kubernetes designed for production usage. This page shows you how to deploy a cluster.
准备开始
一个可用的 Juju 客户端 ;不一定要是 Linux 机器,也可以是 Windows 或 OSX。
一个受支持的云 。
裸机部署可以通过 MAAS 实现。 配置指南参见 MAAS 文档 。
OpenStack 部署目前只在 Icehouse 及更新版本上测试通过。
下面任一一种选项:
可以网络访问以下站点
*.jujucharms.com
gcr.io
github.com
访问 Ubuntu 镜像源(公共的或私有的)
通过这些 步骤准备好离线部署。
Deployment overview
Out of the box the deployment comes with the following components on 9 machines:

Ubuntu Kubernetes 的部署通过名为 charms 的开源运维工具实现,这类工具也称作运维即代码(Operations as Code)。
这些 charms 以层的方式组装,从而使代码更小,更专注于 Kubernetes 及其组件的操作。
Kubernetes 的层和 Bundle 可以在 github.com 的 kubernetes
项目中找到:
