Today, etcdctl endpoint health only performs a quorum GET. If server is corrupted or exceeded quota (which put the server into read only mode), this command incorrectly returns healthy.

How should I use alicloud MNS?

Basically we're in the DAG, so make sure we've let all the other resources (like files) get built (that might be used for the file server) before the server sends anything out. We could either block or just not return anything yet.

As an aside, does the rf.ReadFrom bit not get cancelled properly on close??

time.NewTicker 在使用过程中，结束的时候一定要 stop。

• 官方 Example 如下：

ticker := time.NewTicker(time.Second) 
defer ticker.Stop() 
done := make(chan bool) 
go func() {     
    time.Sleep(10 * time.Second)     
    done <- true 
}() 
for {     
    select {
     case <-done:
      

Of the learning environments that leverage Ansible, very few are using roles. This can make porting Ansible playbooks across learning environments more difficult. To fix this, Ansible-using learning environments need to be refactored (where possible) to use an Ansible role.

this might be out of scope since it's easy enough to get with etcdctl but should the info subcommand print the etcd version?

feel free to close this if it's out of scope.
