etcdctl 抛出错误：超出上下文截止日期错误

Question

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，它有一个指向 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。 我已经使用以下配置使用cfssl生成了证书

证书生成错误还是我错过了什么？

Answer 1

证书是为etcd.uday.com生成的。 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etcdctl etcd.udayvishwakarma.com为etcd.uday.com 。

Answer 2

我今天遇到了同样的问题，可能这对你现在没有用，但它对将来遇到同样问题的任何人都有用。 我想你可能失踪了

etcd.udayvishwakarma.com

从你的证书

--cert=etcd-client.pem 

要验证 etcd.udayvishwakarma.com 是否存在于您的证书中，您可以运行：

openssl x509 -in etcd-client.pem -text

您应该能够在 X509v3 Subject Alternative Name 下看到它。 如果不这样做，您可能需要重新创建证书并添加该 DNS 名称。

Answer 3

当我运行.\etcdctl.exe put key value 时，我收到此错误

 Error: context deadline exceeded

在运行etcdctl.exe ，您应该先运行etcd.exe 。 就我而言，它正在工作。
