HA 1.12 有几个问题:
1,keepalived.conf 配置文件authentication 没有写。
2,主管理服务器挂了,dashboard web界面无法访问。
3,新节点加入需要自己拷贝相关证书。

- 已加
- 理论上dashboard web依然可以访问,不过不能再用master0的IP了
- ansible里已经实现了新增节点的功能,请见:https://github.com/fanux/sealos/blob/master/roles/kube-node/tasks/main.yaml

HA 1.12.2有几个问题:
1,新增node节点的流程是将之前上线的node节点reset后再重新添加至集群中吗?
2,主master关机后,vip_dashboard就不能访问了,只能访问副master_ip_dashboard
3,做完HA后,所有master节点上的kubelet调用还是各自的ip,并不是VIP
from fanux.github.io.
- 新增节点时配置文件中不要写老的node IP了,如果有老的nodeIP删除掉,masterIP不要删,这样只会把新增节点清理一下
- 应该需要大概五分钟的恢复时间
- master节点上的不需要配置VIP,因为每个master都有APIserver,挂了无所谓
