從GitHub Dockerpool社區賬戶下載Mongodb鏡像項目：

git clone https://github.com/DockerPool/Mongodb.git 並修改文件

[root@docker1 Mongodb]# ls

Dockerfile mongodb-3.2.repo mongodb-linux-x86_64-rhel70-3.6.0.tgz run.sh set_mongodb_password.sh

其中Dockerfile內容為：

[root@docker1 Mongodb]# vi Dockerfile

#設置從我們之前創建的sshd鏡像繼承

FROM sshd:centos

MAINTAINER waitfish from dockerpool.com

ADD mongodb-3.2.repo /etc/yum.repos.d/

RUN \

yum update -y && \

yum install -y mongodb-org && \ #這裏不推薦使用yum安裝monodb，實在下載速度太慢

yum clean all

# 創建mongodb存放數據文件的文件夾

RUN mkdir -p /data/db

VOLUME /data/db

ENV AUTH yes

# Add run scripts 添加腳本

ADD run.sh /run.sh

ADD set_mongodb_password.sh /set_mongodb_password.sh

RUN chmod 755 ./*.sh
