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。

导入集群

# 获取 Api Server
[root@k8s-master01 ~]# cat ~/.kube/config | grep server: | awk '{print $2}'
https://192.168.1.69:8443

# 获取 Router
# 若使用kubeadm安装可以使用如下命令进行查看 ，若二进制安装使用节点IP即可
[root@k8s-master01 ~]# kubectl -n kube-system get pod -o wide | grep kube-proxy
[root@k8s-master01 ~]# 

# 获取 Token
[root@k8s-master01 ~]# vim 123.yaml
[root@k8s-master01 ~]# cat 123.yaml

# 1.23 以及以下可以使用如下命令查看
[root@k8s-master01 ~]# kubectl -n kube-system describe secret $(kubectl -n kube-system get secret | grep kubeoperator-user | awk '{print $1}') | grep token: | awk '{print $2}'
[root@k8s-master01 ~]# 
[root@k8s-master01 ~]# 

# 1.24 版本使用如下命令创建token
