经过两天的折腾，终于实现了自己想要的效果，就是通过docker-compose 部署最新的mongodb replicaSet， 主要是为了测试 4.2 最新的多文档事务，下面将整个步骤分享一下：

docker-compose.yml 内容如下：

version: '3.4'
    
    services:
        mongo:
            container_name: mongodb
            image: mongo:latest
            hostname: mongodb
            volumes:
              - /data/mongodb/mongod.conf:/etc/mongod.conf
              - /data/mongodb/data/db/:/data/db/
              - /data/mongodb/data/log/:/var/log/mongodb/
              - /data/mongodb/initdb.d/:/docker-entrypoint-initdb.d/
            environment:
              - MONGO_INITDB_ROOT_USERNAME=root
              - MONGO_INITDB_ROOT_PASSWORD=123456
            ports:
                - "27017:27017"
            healthcheck:
                test: test $$(echo "rs.initiate().ok || rs.status().ok" | mongo -u root -p '123456' --quiet) -eq 1
                interval: 10s
                start_period: 30s
            command: ["--replSet", "rs0", "--bind_ip_all"]

说明：

1、 /data/mongodb/mongod.conf  文件需要提前建好，内容如下，主要是启用验证，如果不挂载这个文件，replicaset 是在裸奔的

# mongod.conf
    
    # for documentation of all options, see:
    #   http://docs.mongodb.org/manual/reference/configuration-options/
    
    # Where and how to store data.
    storage:
      dbPath: /data/db
      journal:
        enabled: true
    #  engine:
    #  mmapv1:
    #  wiredTiger:
    
    # where to write logging data.
    systemLog:
      destination: file
      logAppend: true
      path: /var/log/mongodb/mongod.log
    
    # network interfaces
    net:
      port: 27017
      bindIp: 127.0.0.1
    
    
    # how the process runs
    processManagement:
      timeZoneInfo: /usr/share/zoneinfo
    
    security:
      authorization: enabled
    
    #operationProfiling:
    
    #replication:
    
    #sharding:
    
    ## Enterprise-Only Options:
    
    #auditLog:
    
    #snmp:

2、 /data/mongodb/initdb.d  此目录下的脚本是用来初始化的，前提是没有任何数据前执行，我在该目录下创建了**create-app-user.sh** 来初始化自定义数据库【yourdb】以及用户名【yourAdmin】密码【123456】，内容如下：

#!/usr/bin/env bash
    echo "Creating mongo users..."
    
    mongo admin -u root -p 123456 << EOF
    db.createUser({user: 'admin', pwd: '123456', roles: [{role: 'userAdminAnyDatabase', db: 'admin'}]});
    db.grantRolesToUser(
       "admin",
       [ "clusterAdmin" ]
    );
    EOF
    
    mongo admin -u admin -p 123456 << EOF
    use yourdb
    db.createUser({user: 'yourdbAdmin', pwd: '123456', roles:[{role:'readWrite',db:'yourdb'}]})
    EOF
    echo "Mongo users created for yourdb."

3、可以用monog client 测试登录：

mongo -u root -p 123456

登录成功后，是这个样子滴：

执行 show dbs； 可以看到自己建了的数据库，测试自己建了的用户和密码，可以使用:

mongo -u yourdbAdmin -p 123456 --authenticationDatabase yourdb
