随着多云多集群的场景越来越丰盛，在各个云厂商环境部署 KubeSphere 的需要随之升高。因为各云厂商的云资源应用规定和菜单导航栏各不相同，会使用户花大量工夫去排错。为升高部署过程错误率，本教程应用华为云平台部署一套高可用的 KubeSphere，心愿能够帮忙到大家进步部署体验。
一、部署后期筹备
所需环境的资源满足以下条件即可：
| 华为云产品 | 数量 | 用处 | 备注 |
|---|---|---|---|
| ECS 云服务器 | 6 | master、node | |
| VPC | 1 | 可用区 | |
| ELB | 2 | 负载平衡 | |
| 平安组 | 1 | 出入口管控 | |
| 公网 IP | 7 | 外网拜访 |
二、云平台资源初始化
1. 创立 VPC
进入到华为云管制，在左侧列表抉择「虚构公有云」，抉择「创立虚构公有云」创立 VPC，配置如下图：
2. 创立平安组
创立一个平安组，设置入方向的规定、关联实例参考如下：
3. 创立实例
在网络配置中，网络抉择第一步创立的 VPC 和子网。在平安组中，抉择上一步创立的平安组。
4. 创立负载均衡器（创立内外两个）
内网 ELB：
外网 ELB：
若集群须要配置公网拜访，则须要为外网负载均衡器配置一个公网 IP 为 所有节点 增加后端监听器，监听端口为 80（测试应用 30880 端口, 此处 80 端口也须要在平安组中凋谢）。
前面配置文件 config.yaml 须要配置在后面创立的 内网 SLB 调配的地址（VIP）

port: "6443"部署 KubeSphere 平台
1. 下载 KK
$ curl -sfL https://get-kk.kubesphere.io | VERSION=v1.1.1 sh -2. 增加执行权限
$ chmod +x kk3. 应用 kubekey 部署
$ ./kk create config --with-kubesphere v3.1.1 --with-kubernetes v1.17.9 -f master-HA.yaml4. 集群配置调整
