Kubernetes 检查etcd运行状况时超出了上下文截止日期

我正在使用以下命令检查etcd（3.3.13）群集状态：

[root@iZuf63refzweg1d9dh94t8Z work]# /opt/k8s/bin/etcdctl endpoint health --cluster
https://172.19.150.82:2379 is unhealthy: failed to connect: context deadline exceeded
https://172.19.104.231:2379 is unhealthy: failed to connect: context deadline exceeded
https://172.19.104.230:2379 is unhealthy: failed to connect: context deadline exceeded
Error: unhealthy cluster

检查etcd成员：

[root@iZuf63refzweg1d9dh94t8Z work]# /opt/k8s/bin/etcdctl member list
    56298c42af788da7, started, azshara-k8s02, https://172.19.104.230:2380, https://172.19.104.230:2379
    5ab2d0e431f00a20, started, azshara-k8s01, https://172.19.104.231:2380, https://172.19.104.231:2379
    84c70bf96ccff30f, started, azshara-k8s03, https://172.19.150.82:2380, https://172.19.150.82:2379

我的集群部署成功了吗？如果没有，如何解决上下文截止时间超过错误？我试过这个：

     export ETCDCTL_API=3
     [root@ops001 ~]# /opt/k8s/bin/etcdctl endpoint status --write-out=table
+----------------+------------------+---------+---------+-----------+-----------+------------+

https://172.19.104.230:2379 is unhealthy: failed to connect: context deadline exceeded
Error: unhealthy cluster

如何解决上下文截止期超过错误

这一错误具有误导性；这通常是由于

etcdctl

未提供凭据和/或未使用与集群相同的

etcdctl\u API=

值造成的。如果它是现代的

etcd

版本，您需要，然后提供用于启动

etcd

本身的相同版本
