可以修改 master 和 node 的名字前缀、部署区域、数量和 VM 类型
- ssh 22 对外由 LB 配置 NAT 端口实现，如配置文件中 50200 → master-0
-
已经包含的规则转换（不含 30880）
服务 协议 规则 后端端口 前端端口 节点池 ssh TCP 入站 NAT 22 50200, 50201, 50202, 50100~50199 主节点, 普通节点 api 服务器 TCP 负载均衡 6443 6443 主节点 ks 控制台 TCP 负载均衡 30880 30880 主节点 http TCP 负载均衡 80 80 普通节点 https TCP 负载均衡 443 443 普通节点
-
- node 使用 VMSS
- ssh 22 对外由 LB 配置 NAT 端口实现，如配置文件中 50200 → master-0

-
部署 K8S cluster
最简单的方式还是用 kk 完成，注意在 kubernetes 1.24 以后，psp 弃用，在 kk 中还有 psp 权限管理，安装的时候会报错。建议使用 1.23.10，也是 kk 现在默认的版本。-
证书传输 → Master-0
scp -i zyi.pem -P 50200 zyi.pem zyi@20.247.0.170:/home/zyi/.ssh/ -
每一台安装 socat 等必须的软件
ssh -i zyi.pem -p50200 zyi@20.247.0.170 'sudo apt install socat conntrack' -
登录到 Mater-0
ssh -i zyi.pem -p50200 zyi@20.247.0.170 -
下载 kk 并赋予可执行权限
curl -sfL https://get-kk.kubesphere.io | VERSION=v3.0.10 sh - chmod +x kk-
创建配置文件模板
./kk create config --with-kubesphere v3.3.2 --with-kubernetes v1.22.12-
KubeSphere 3.3 对应 Kubernetes 版本推荐：v1.20.x、v1.21.x、* v1.22.x、* v1.23.x 和 * v1.24.x。带星号的版本可能出现边缘节点部分功能不可用的情况。因此，如需使用边缘节点，推荐安装 v1.21.x。如果未指定 Kubernetes 版本，KubeKey 将默认安装 Kubernetes v1.23.10。有关支持的 Kubernetes 版本请参阅支持矩阵。
-
如果在此步骤中的命令中未添加标志
-with-kubesphere，则不会部署 KubeSphere，除非您使用配置文件中的addons字段进行安装，或稍后使用./kk create cluster时再次添加此标志。 -
如果在未指定 KubeSphere 版本的情况下添加标志 --with kubesphere`，将安装 KubeSphere 的最新版本。
