安裝KubeOperator并導入現有叢集進行管理
介紹
KubeOperator 是一個開源的輕量級 Kubernetes 發行版，專注于幫助企業規劃、部署和營運生産級别的 Kubernetes 叢集。
KubeOperator 提供可視化的 Web UI，支援離線環境，支援實體機、VMware、OpenStack 和 FusionCompute 等 IaaS 平台，支援 x86 和 ARM64 架構，支援 GPU，内置應用商店，已認證 CNCF 的 Kubernetes 軟體一緻性認證。
KubeOperator 使用 Terraform 在 IaaS 平台上自動建立主機（使用者也可以自行準備主機，比如實體機或者虛機），通過 Ansible 完成自動化部署和變更操作，支援 Kubernetes 叢集 從 Day 0 規劃，到 Day 1 部署，到 Day 2 營運的全生命周期管理。
