1 month ago 想了想，打算自己加etcd的配置文件。看了一下kubekey生成etcd配置文件的template。 如下：

`)))这里有些变量名称，还得斟酌一下，怕填错。
有没有大佬一起填一下这个变量

A clear and concise description of what happend.
[ETCDConfigureModule] Health check on exist etcd
Relevant log output
我看了一下源码，到了ETCDConfigureModule。
应该就是到了上图红框里这部分。
因为是新建集群，那么我们就认为是走的handleNewCluster
handleNewCluster的源码如下：
existETCDHealthCheck 按道理应该是这个handleNewCluster里放到restart后才执行的才对吧。新建集群，在ETCDConfigureModule之前执行了InstallETCDBinaryModule，那么代表etcd是安装了，但是InstallETCDBinaryModule并没有生成 etcd.env。所以接下来在handleNewCluster即ConfigureModule中的执行顺序应该是
其实 existETCDHealthCheck,在新建集群是不是都没必要了。
然后我看了一下etcd.service
配置文件在 /etc/etcd.env
查了一下这个，文件不存在。 配置文件不存在，就代表InstallETCDBinaryModule安装etcd之后，是无法启动etcd的，导致后面ETCDConfigureModule中existETCDHealthCheck是会报错的。因为etcd没启动。 看一下当前节点etcd的状态
那么问题出来了，这个问题出现的原因是 在没用生成 etcd.env的前提下，检查了etcd的健康度。
是否可以出一个紧急的版本修复一下这问题？
