Kubernetes 服务、Redis Sentinel 未一致返回 Redis 主 IP 和端口

问题描述 投票:0回答:1

Kubernetes 服务、Redis Sentinel 未一致返回 Redis 主 IP 和端口,并且所有 pod 都位于 docker 容器中。 我已经使用了https://github.com/kubernetes/kubernetes/tree/master/examples/redishttps://github.com/helm/helm - Redis 集群

当我连接到 Kubernetes 服务(10.3.251.152、26379/TCP)时,它应该确定 Redis Sentinel master(ip:'10.0.0.68',端口:'6379'),然后与其建立连接。但有时,Kubernetes 服务会返回(ip:'10.0.0.68',端口:'6379'),有时,它会返回 Kubernetes 服务(10.3.251.152,26379/TCP)作为哨兵主 IP。我们可以在程序日志中看到这些来与哨兵大师连接

在这两种情况(kubernetes sentinel 示例、helm.sh 的 redis 集群)情况下都会发生这种不一致。

您可以在此处查看服务和 Pod 详细信息..

    and so on .. 
   }
  }

查看 Redis Sentinel Gateway — 它有助于管理 Redis 故障转移,而无需在应用程序代码中实现 Sentinel 支持。非常适合需要高可用性的遗留应用程序!
