step 2

exec -ti mongo1 bash
mongo var cfg = { "_id": "rs0", "version": 1, "members": [ { "_id": 0, "host": "mongo1:27017", "priority": 2 }, { "_id": 1, "host": "mongo2:27017", "priority": 0 }, { "_id": 2, "host": "mongo3:27017", "priority": 0 } ] }; rs.initiate(cfg);

step 3 nodejs connect mongodb

const connection = 'mongodb://mongo1:27017,mongo2:27017,mongo3:27017/{db}?replicaSet=rs0';
  
console.log('Mongoose version:', mongoose.version);
mongoose.set('useUnifiedTopology', true);

return mongoose.connect(connection, {
                                        useNewUrlParser : true,
                                        useFindAndModify: false, // optional
                                        useCreateIndex  : true,
                                        // replicaSet      : 'rs0', // We use this from the entrypoint in the docker-compose file
                                        // dbName: 'mongo_test'
                                    });

step 4 const mongoose = require('mongoose') const Schema = mongoose.Schema

const productSchema = new Schema({
name:  String,
category: String,
price: Number,
tags: [String]
}, { timestamps: true, versionKey: false })

const ProductModel = mongoose.model('Product', productSchema)

ProductModel.watch().on('change', data => console.log(new Date(), data)); <<ทุกครั้งที่มีการ add, update, delete จะมี watch() change ทุกครั้ง

step 5 สามารถใช้งานได้ปกติ ###################### mongodb ######################
