安装KubeOperator并导入现有集群进行管理
介绍
KubeOperator 是一个开源的轻量级 Kubernetes 发行版，专注于帮助企业规划、部署和运营生产级别的 Kubernetes 集群。
KubeOperator 提供可视化的 Web UI，支持离线环境，支持物理机、VMware、OpenStack 和 FusionCompute 等 IaaS 平台，支持 x86 和 ARM64 架构，支持 GPU，内置应用商店，已通过 CNCF 的 Kubernetes 软件一致性认证。
KubeOperator 使用 Terraform 在 IaaS 平台上自动创建主机（用户也可以自行准备主机，比如物理机或者虚机），通过 Ansible 完成自动化部署和变更操作，支持 Kubernetes 集群 从 Day 0 规划，到 Day 1 部署，到 Day 2 运营的全生命周期管理。
