这是一个相当简单的场景，我不知道为什么它不工作。
我有一个docker compose

  1. version: '3.8'
  3. services:
  4.   mongodb:
  5.     image: mongo:latest
  6.     command: ["mongod", "--replSet", "rs0", "--bind_ip_all"]
  7.     ports:
  8.       - "27017:27017"

我运行docker-compose up来旋转它
我看到一些木头

我可以用mongosh连接到它

我初始化副本集

  1. test> rs.initiate()
  2. {
  3.   info2: 'no configuration specified. Using a default configuration for the set',
  4.   me: '5d44bda7d148:27017',
  5.   ok: 1

我可以看到当前配置

  1. rs0 [direct: other] test> rs.config()
  2. {
  3.   _id: 'rs0',
  4.   version: 1,
  5.   term: 1,

现在我打开，在我的主机（Windows）3 T工作室，我创建连接.
此连接字符串工作正常

  1. mongodb://127.0.0.1:27017

型

此连接字符串未连接

  1. mongodb://127.0.0.1:27017/?replicaSet=rs0&ssl=false

为什么
显然副本集运行正常，很明显我可以访问服务器
3 T Studio显示超时错误

  1. SERVER [5d44bda7d148:27017] (Type: UNKNOWN) 
  2. |_/ Connection error (MongoSocketOpenException): Exception opening socket
  3. |____/ Unknown host: 5d44bda7d148
  5. Details:
  6. Timed out after 30000 ms while waiting for a server that matches com.mongodb.client.internal.MongoClientDelegate$1@482d37d9.

我需要让MongoDb副本集在本地作为docker容器运行，因为我需要它进行更改流的本地开发。我希望得到解释和解决方案。

**更新1（2023-12-21）**我也试过

  1. command: ["mongod", "--replSet", "rs0", "--bind_ip", "localhost"]

型
在docker composer中，根据https://www.mongodb.com/docs/manual/tutorial/deploy-replica-set/#ip-binding，但没有运气

docker

似乎问题是与主机的副本集是默认配置的。它似乎选择了容器ID，这不是我想要的。
如果我连接到mongosh并这样做：

  1. let cfg = rs.config()
  2. cfg.members[0].host = 'localhost:27017'
  3. rs.reconfig(cfg)

字符串
本质上就是修改宿主，

  1. rs0 [direct: primary] test> rs.config()
  2. {
  3.   _id: 'rs0',
  4.   version: 3,
  5.   term: 1,
  6.   members: [
  7.     {
  8.       _id: 0,
  9.       host: '127.0.0.1:27017',
  10.       arbiterOnly: false,
  11.       buildIndexes: true,
  12.       hidden: false,
  13.       priority: 1,
  14.       tags: {},
  15.       secondaryDelaySecs: Long('0'),
  16.       votes: 1
  17.     }
  18.   ],
  19.   protocolVersion: Long('1'),
  20.   writeConcernMajorityJournalDefault: true,
  21.   settings: {
  22.     chainingAllowed: true,
  23.     heartbeatIntervalMillis: 2000,
  24.     heartbeatTimeoutSecs: 10,
  25.     electionTimeoutMillis: 10000,
  26.     catchUpTimeoutMillis: -1,
  27.     catchUpTakeoverDelayMillis: 30000,
  28.     getLastErrorModes: {},
  29.     getLastErrorDefaults: { w: 1, wtimeout: 0 },
  30.     replicaSetId: ObjectId('6584bfe7812f7983ae2da944')
  31.   }
  32. }

型
我现在可以从主机连接到

  1. mongodb://localhost:27017/?replicaSet=rs0

型
这感觉很古怪，但似乎很有效。
更新
另一个更简洁的选择是连接到mongosh并执行此操作，以传递配置而无需重新配置

  1. test> const configuration = { _id: "rs0", members: [{ _id: 0, host: "127.0.0.1:27017"}]}
  3. test> rs.initiate(configuration)

型
这给了我一个类似的结果，其中主机具有127.0.0.1或localhost而不是容器ID。
