Question

我想通过docker-compose部署包含1个mongo shard（副本集），1个configserver（副本集）和1个路由器的mongo集群。我有一个问题，它是“无法达到设置mongoconfigserver的主要”。我发现了一个问题： Unable to launch mongos，但在这种情况下，config-server没有副本集，而我在命令中需要“--replSet mongoconfigserver”选项。

这是我的docker-compose.yml：

version: '3'
services:
  # Config servers for metadata
  mongoconfigserver-01:
    container_name: mongoconfigserver-01
    image: mongo
    command: mongod --configsvr --replSet mongoconfigserver --dbpath /data/db --port 27017
    volumes:
        - /etc/localtime:/etc/localtime:ro
        - /mongo_cluster/config1:/data/db
  mongoconfigserver-02:
    container_name: mongoconfigserver-02
    image: mongo
    command: mongod --configsvr --replSet mongoconfigserver --dbpath /data/db --port 27017
    volumes:
        - /etc/localtime:/etc/localtime:ro
        - /mongo_cluster/config2:/data/db
  mongoconfigserver-03:
    container_name: mongoconfigserver-03
    image: mongo
    command: mongod --configsvr --replSet mongoconfigserver --dbpath /data/db --port 27017
    volumes:
        - /etc/localtime:/etc/localtime:ro
        - /mongo_cluster/config3:/data/db    
  # First shard 
  mongo-shard-01a:
    image: mongo

    command: mongod --port 27018 --replSet mongo-shard-01 --dbpath /data/db
    volumes:
        - /etc/localtime:/etc/localtime:ro
        - /mongo_cluster/data1:/data/db
    ports:
        - 27017:27017
  mongo-shard-01b:
    image: mongo
    command: mongod --port 27018 --replSet mongo-shard-01 --dbpath /data/db
    volumes:
        - /etc/localtime:/etc/localtime:ro
        - /mongo_cluster/data2:/data/db
    ports:
        - 27027:27017
  mongo-shard-01c:
    image: mongo
    command: mongod --port 27018 --replSet mongo-shard-01 --dbpath /data/db
    volumes:
        - /etc/localtime:/etc/localtime:ro
        - /mongo_cluster/data3:/data/db
    ports:
        - 27037:27017
  # Mongo router
  mongo-router-01:
    container_name: mongo-router-01
    image: mongo
    depends_on:
        - mongoconfigserver-01
        - mongoconfigserver-02
        - mongoconfigserver-03
        - mongo-shard-01a
        - mongo-shard-01b
        - mongo-shard-01c
    command: mongos --configdb mongoconfigserver/mongoconfigserver-01:27017,mongoconfigserver-02:27017,mongoconfigserver-03:27017
    volumes:
        - /etc/localtime:/etc/localtime:ro

和日志：

有人可以帮忙吗？

在配置服务器中设置以下参数。

use admin
config = {
    _id : "configs",
    members : [
    {_id : 0, host : "ip:21000" },
    {_id : 1, host : "ip:21000" },
    {_id : 2, host : "ip:21000" }
    ]
}
rs.initiate(config);

无法访问set mongo config server的任何节点
