1、下载mongo的image
~ » docker pull mongo:4

2、启动mongo
docker run -p 27017:27017 -v /data/docker/mongodb:/data/db -v /data/docker/mongodb:/data/configdb -d mongo:4 --auth
这里数据存放在 /data/docker/mongodb 文件夹，这里注意mac下需要sharing下文件夹。
--auth表示开启权限相关
3、验证
本地没有mongo的客户端，使用容器里面的客户端链接执行
第一次使用host报错
/data/docker/mongodb » docker exec -it 25f796b9b97c mongo --host 172.17.28.85
MongoDB shell version v4.0.10
connecting to: mongodb://172.17.28.85:27017/?gssapiServiceName=mongodb
2019-07-23T07:44:40.439+0000 E QUERY [js] Error: couldn't connect to server 172.17.28.85:27017, connection attempt failed: SocketException: Error connecting to 172.17.28.85:27017 :: caused by :: No route to host :
connect@src/mongo/shell/mongo.js:344:17

第二次使用localhost成功
/data/docker/mongodb » docker exec -it 25f796b9b97c mongo --host localhost
MongoDB shell version v4.0.10

Enable MongoDB's free cloud-based monitoring service, which will then receive and display
metrics about your deployment (disk utilization, CPU, operation statistics, etc).
The monitoring data will be available on a MongoDB website with a unique URL accessible to you
and anyone you share the URL with. MongoDB may use this information to make product
improvements and to suggest MongoDB products and deployment options to you.
To enable free monitoring, run the following command: db.enableFreeMonitoring()
To permanently disable this reminder, run the following command: db.disableFreeMonitoring()

使用本机IP不通的问题可能是和防火墙有关系，网上说使用localhost可行，我试了试确实可以。
4、权限处理
刚才加了--auth后需要添加mongo的账号，使用下面命令登录即可：
docker exec -it 21aeff91b61e6ebfe2b347e0a7549510abcd4eeb8b095d51dfbb1360951864a5 mongo admin
然后使用mongo的命令create user，授权等；具体命令查看mongo文档。
不加--auth，测试环境裸奔一下也无妨。
