mongodb-sharded:4.4 [无法加入分片集群]

[英]mongodb-sharded:4.4 [Unable to join the sharded cluster]

问题描述

我从部署在每个 Sharded mongo 上的主副本集（mongodb-shard01 和 mongodb-shard10）收到无法加入分片集群错误。 我在 .net 上看到过类似的问题，但没有明确的答案。 也许有人知道吗？

我解决了我的问题。

我缺少的是 docker-compose.yml 中声明的每个 replicaSet 的仲裁器。 所以我需要为 repSetShard0 和 repSetShard1 声明一个仲裁器。

此外，当我在所有容器启动后重新启动 configsvr [mongodb-cfg] 时，我没有收到错误“无法到达 shard01 的主要节点”

希望这会帮助别人......
