Deploying MongoDB Replica sets in Docker

1. Basic information as follows server address 192.168.73.129 replica set name RS container node and port mapping M0 37017:27017 M1 47017:27017 m2 57,017:27,017 Note: Machine Environment installation doc Ker2. Deployment Step 2.1 Download MONGO image

Docker pull Mongo

2.2 Starting three nodes

Docker run--name m0-p 37017:27017-d MONGO--replset "RS" Docker run--name m1-p 47017:27017-d MONGO--replset "RS" dock Er run--name m2-p 57017:27017-d MONGO--replset "RS"

Docker ps-a//View boot container

2.3 Connect any node for replica set configuration

Enter one of the containers: Docker exec-it De242cc5fa5a/bin/bash

Connect any one of the three nodes, note that the IP address is the host IP, my current 192.168.73.129

mongo --host 192.168.73.129 --port 37017

Now connected to the M0 node for replica set configuration

var config={ _id: "rs", members:[ {_id:0,host: "192.168.73.129:37017"}, {_id:1,host: " 192.168.73.129:47017 "}, {_id:2,host:" 192.168.73.129:57017 "}]};rs.initiate (config)

The response should resemble the following, note that at this point the command prompt has changed from the original > into rs:secondary>

{ "OK": 1, "Operationtime": Timestamp (1522810920, 1), "$clusterTime": { "clustertime": Timestamp ( 1522810920, 1), "signature": { "hash": Bindata (0, "aaaaaaaaaaaaaaaaaaaaaaaaaaa="), "KeyId": Numberlong ( 0)}}}
