mongodb - 无法连接到工作的Dockerized Mongo ReplSet

Question

我正在尝试使用以下docker-compose文件创建在本地运行的Mongo ReplicaSet:

version: '2.0'

services:
  db01:
    image: mongo:3.4
    mem_limit: 512m
    restart: always
    ports:
      - "27017:27017"
    volumes:
      - datadb01:/data/db
      - ./etc/mongod.conf:/etc/mongod.conf
    command: mongod --smallfiles --noIndexBuildRetry --replSet rs0
    container_name: db01
    networks:
      - mongo

  db02:
    image: mongo:3.4
    mem_limit: 512m
    restart: always
    ports:
      - "27018:27017"
    volumes:
      -  datadb02:/data1/db
      - ./etc/mongod.conf:/etc/mongod.conf
    command: mongod --smallfiles --noIndexBuildRetry --replSet rs0
    container_name: db02
    networks:
      - mongo

因此，这实际上似乎可行!我不会发布全部内容，但是当我运行rs.status()时，我得到以下信息:

{
  "set" : "rs0",
  ...
  "ok" : 1
}

但是，当我尝试连接到copysetSet而不是单个节点时，会收到以下错误日志:

~/utils/infrastructure/content-repl-set [replay-content*]: mongo --host rs0/127.0.0.1:27017,127.0.0.1:27018

2018-09-10T17:50:42.684-0400 W NETWORK  [js] Unable to reach primary for set rs0

我的最佳猜测是mongo shell(以及其他mongo驱动程序，例如pymongo)不知道我在docker容器中指定的容器名称。有没有办法将此信息公开给我的本地计算机？还是我记错了？谢谢你的帮助

您正在使用MacOS吗？如果是这样，似乎docker中的那些内部IP地址无法访问，因为docker(Linux)桥接网络无法从macOS主机访问。
