一：创建挂载目录

	[root@VM-12-7-centos local]# cd dev/
	[root@VM-12-7-centos dev]# ls 
	elasticsearch  gitlab  java  jenkins
	[root@VM-12-7-centos dev]# mkdir mongodata
	[root@VM-12-7-centos dev]# pwd

二：拉取镜像

 	docker pull mongo:latest

三：运行容器

	docker run -itd --name mongo-data-one -p 8087:27017 -v /usr/local/dev/mongodata:/data/db mongo:latest

	-p: 映射端口；
	-v  MongoDB数据挂载目录；
	镜像名；

四：进入容器创建用户

[root@VM-12-7-centos dev]# docker exec -it  6adae0bedd5d mongo admin

        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()
