Mongodb FailedToSatisfyReadPreference:找不到与读取首选项匹配的主机{mode:“primary”}
我想在我的项目中使用mongodb shard。我创建了一个舵图，部署到库伯内特斯集群 我使用本地运行的Mongodb FailedToSatisfyReadPreference:找不到与读取首选项匹配的主机{mode:“primary”},mongodb,kubernetes-helm,Mongodb,Kubernetes Helm,我想在我的项目中使用mongodb shard。我创建了一个舵图，部署到库伯内特斯集群 我使用本地运行的kind集群来测试它。配置服务器和碎片服务器正在正常运行。我能够在他们的mongo shell中执行命令。mongos服务器无法连接到config server中的副本集。我在mongos中收到以下错误消息 2020-04-17T13:33:31.579+0000 W SHARDING [replSetDistLockPinger] pinging failed for distribute

我无法进一步调试它 您的配置服务器副本集是：
- 未运行（并非所有节点都已启动）
- 不是副本集（replSetInitiate未执行或失败）
- 从碎片节点引用不正确（错误的主机、ip或错误的副本集名称）
- 已启动并正在运行，但由于防火墙规则，不允许您的碎片访问它
