如何建立容器環境？

你的環境能使用 Windows Container 嗎？硬體需求• 支援虛擬化的處理器 (Intel VT-x)• 4GB 記憶體• 若是執行 Hyper-V Container ，則虛擬機器內至少要 2 顆 vCore軟體需求• Windows Server 2016 或 Windows 10 週年版作為 Container

Host 。• 若是執行 Windows Server Container ，則要安裝容器功能；若是執行 Hyper-V Container ，則要啟用 Hyper-V 角色。• Windows Server Container 要求作業系統一定要安裝在 C: ，但此規則不影響 Hyper-V Container 。

巢狀虛擬化 (Nested Virtualization)Run Hyper-V in Hyper-V• 主要動機：支援 Hyper-V Containers 於任何的雲端環境• 額外的好處：做 lab 更容易了。

1. 安裝 Hyper-V 功能於主機2. 於主機建立一個要執行 Hyper-V Container 的 VM3. 安裝 Windows Server 2016 or Nano Server 至 VM4. 將虛擬機器關機，於主機啟動虛擬機器的巢狀虛擬化功能5. 將虛擬機器開機，安裝 Hyper-V 功能6. 於主機上對 Hyper-V Container 下指令

映像登錄資料庫 (Image Registry)Docker Hub 與 Docker Store公開，官方與私有映像儲存庫由組織支援的細粒存取控制自動化映像建置支援Docker 受信任登錄企業級私有登錄資料庫運行於你的基礎建設 ( 地端或雲端 )AD 與以角色為主的存取控制Docker 登錄資料庫以開源為基礎以容器的方式運行於你的基礎建設 ( 地端或雲端 )https://docs.docker.com/registry and or https://github.com/docker/distribution
