k8s离线安装进阶版
# 1.参考之前的文章做好以下几点：
- 下载kubernetes 离线安装包.
- 下载最新版本sealos.
- 务必同步服务器时间
- 主机名不可重复
然后，一条命令搞定k8s集群（哭了）

[root@master ~]#
- 增加master
sealos join --master 192.168.0.6 --master 192.168.0.7
sealos join --master 192.168.0.6-192.168.0.9 # 或者多个连续IP
- 增加node
sealos join --node 192.168.0.6 --node 192.168.0.7
sealos join --node 192.168.0.6-192.168.0.9 # 或者多个连续IP
- 删除指定master节点
注意clean不加任何参数会清理整个集群
sealos clean --master 192.168.0.6 --master 192.168.0.7
sealos clean --master 192.168.0.6-192.168.0.9 # 或者多个连续IP
- 删除指定node节点
sealos clean --node 192.168.0.6 --node 192.168.0.7
sealos clean --node 192.168.0.6-192.168.0.9 # 或者多个连续IP
# 3.dashboard访问
sealos install --pkg-url https://github.com/sealstore/dashboard/releases/download/v2.0.0-bata5/dashboard.tar
使用上述命令安装完dashboard后日志中会输出token，登录页面时需要使用.
https://你的master地址:32000 chrome访问不了就用火狐
或者使用此命令获取token
kubectl get secret -nkubernetes-dashboard \
$(kubectl get secret -n kubernetes-dashboard|grep dashboard-token |awk '{print $1}') \
-o jsonpath='{.data.token}' | base64 --decode本文参与 腾讯云自媒体同步曝光计划，分享自作者个人站点/博客。
