【docker】基于Dockerfile构建monogdb服务镜像

标签：monogdb服务镜像

从GitHub Dockerpool社区账户下载Mongodb镜像项目：

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

[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内容为：

[root@docker1 Mongodb]# vi Dockerfile

#设置从我们之前创建的sshd镜像继承

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 && \         #这里不推荐使用yum安装monodb，实在下载速度太慢

  yum clean all

# 创建mongodb存放数据文件的文件夹

RUN mkdir -p /data/db

VOLUME /data/db

ENV AUTH yes

# Add run scripts 添加脚本

ADD run.sh /run.sh

ADD set_mongodb_password.sh /set_mongodb_password.sh

RUN chmod 755 ./*.sh

EXPOSE 27017

EXPOSE 28017

CMD ["/run.sh"]
