【中文标题】etcdctl 抛出错误：超出上下文期限错误【英文标题】：etcdctl throws Error: context deadline exceeded error 【发布时间】：2019-05-07 20:43:53 【问题描述】：

我正在尝试使用 coreos cloud-config 在 AWS 上创建一个单节点 etcd 集群。我创建了一个值为 etcd.uday.com 的 Route53 记录集，它具有指向 ec2 实例的 ELB 的别名。 Etcd 运行成功，但是当我运行 etcd member list 命令时出现以下错误

ETCDCTL_API=3 etcdctl member list \
--endpoints=https://etcd.udayvishwakarma.com:2379 \
--cacert=./ca.pem \
--cert=etcd-client.pem \
--key=etcd-client-key.pem

Error: context deadline exceeded

但是，当--insecure-skip-tls-verify 标志添加到etcdctl member list 命令时，它会列出成员。我已经使用cfssl 使用下面的配置生成了证书

     cfssl gencert -ca=ca.pem -ca-key=ca-key.pem -hostname="etcd.uday.com" \

是证书生成错误还是我错过了什么？

【问题讨论】：

【参考方案1】：

为etcd.uday.com 生成证书。您正在尝试使用etcd.udayvishwakarma.com 进行连接，而证书对etcd.uday.com 有效。将etcdctl 上的端点从etcd.udayvishwakarma.com 更改为etcd.uday.com。

我今天遇到了同样的问题，可能现在这对你没有用，但对以后遇到同样问题的任何人都有用。我想你可能错过了
