KubeSphere®️ 是在目前主流容器调度平台 Kubernetes 之上构建的企业级分布式多租户容器管理平台，提供简单易用的操作界面以及向导式操作方式，在降低用户使用容器调度平台学习成本的同时，极大减轻开发、测试、运维的日常工作的复杂度，旨在解决 Kubernetes 本身存在的存储、网络、安全和易用性等痛点。除此之外，平台已经整合并优化了多个适用于容器场景的功能模块，以完整的解决方案帮助企业轻松应对敏捷开发与自动化运维、微服务治理、多租户管理、工作负载和集群管理、服务与网络管理、应用编排与管理、镜像仓库管理和存储管理等业务场景。
环境准备
本文安装KubeSphere使用到的相关工作环境具体如下：
| 系统版本 | 平台 | IP地址 | 角色 | 配置 |
|---|---|---|---|---|
| Centos7.4 | 阿里云 | 176.101.53.89 | allinnoe | CPU:16核对 内存：32GB 系统盘: 500G |
- KUBESPHERE版本 离线版2.02
安装KubeSphere
安装模式
KubeSphere 安装支持 all-in-one和 multi-node两种模式，即支持单节点和多节点安装两种安装方式。
- All-in-One模式（本文采取此模式）
All-in-One模式即单节点安装，支持一键安装，仅建议用来测试或熟悉安装流程和了解 KubeSphere 高级版的功能特性，在正式使用环境建议使用 Multi-Node 模式。 - Multi-Node模式
Multi-Node 即多节点集群安装，高级版支持 master 节点和 etcd 的高可用，支持在正式环境安装和使用
安装包准备
curl -L https://kubesphere.io/download/offline/advanced-2.0.2 > advanced-2.0.2.tar.gz && tar -zxf advanced-2.0.2.tar.gz && cd kubesphere-all-offline-advanced-2.0.2/scripts
开始安装
KubeSphere 安装过程中将会自动化地进行环境和文件监测、平台依赖软件的安装、Kubernetes 和 etcd 的自动化安装，以及存储的自动化配置。最新的 Installer 默认安装的 Kubernetes 版本是 v1.13.5，安装成功后可通过 KubeSphere 控制台右上角点击关于查看安装的版本。
1.建议使用root用户进行安装，执行install.sh脚本
./install.sh
2.输入数字1选择第一种即all-in-one模式开始极速安装：

删除该记录，并删除命名空间中kube-system中的coredns.pod删除后，会重新建立。
[root@ks-allinone ~]# kubectl delete pod coredns-59647c5bf6-m2lf2 -n kube-system

发现依旧处于该状态,故执行下列命令
kubectl -n kube-system edit cm coredns
删除upstream和proxy那两行，然后执行下列命令
kubectl -n kube-system scale deploy coredns --replicas=0 && kubectl -n kube-system scale deploy coredns --replicas=1
deployment.extensions/cdoredns scaled
deployment.extensions/coredns scaled
此时再次查看命名空间下的openpitrix-system下的pod状态
