1、所需软件包和环境
Centos-7.repo epel-7.repo saolei.zip
server1：部署docker扫雷案例
server2：部署apache，将saolei.zip软件包上传上去
[root@130 ~]# dnf -y install httpd
[root@130 ~]# cd /var/www/html/
[root@130 html]# ls
[root@130 html]# dnf -y install lrzsz
[root@130 html]# rz -E
rz waiting to receive.
[root@130 html]# ls
saolei.zip
[root@130 html]# systemctl start httpd
[root@130 html]# systemctl stop firewalld.service
[root@130 html]# systemctl disable firewalld.service
Removed /etc/systemd/system/multi-user.target.wants/firewalld.service.
Removed /etc/systemd/system/dbus-org.fedoraproject.FirewallD1.service.
[root@130 html]# vim /etc/selinux/config
SELINUX= disabled
2、编辑Dockerfile，使用基础镜像centos:7
[root@133 ~]# vim Dockerfile
FROM centos:7
MAINTAINER [email protected]
ADD Centos-7.repo /etc/yum.repos.d/
ADD epel-7.repo /etc/yum.repos.d/
RUN yum -y install tomcat unzip curl
WORKDIR /var/lib/tomcat/webapps/
RUN curl -O http://192.168.78.130/saolei.zip && \
unzip saolei.zip && \
mv saolei ROOT
ADD jay.sh /jay.sh
EXPOSE 8080
CMD ["/bin/bash","/jay.sh"]
[root@133 ~]# vim jay.sh
#!/bin/bash
/usr/libexec/tomcat/server start
3、构建镜像saolei:v1
[root@130 ~]# docker build -t saolei:v1 .

5、使用浏览器访问http://自己docker服务器的ip/saolei.jsp，能够实现扫雷游戏的使用
可道云实例
1、所需软件包
Centos-7.repo epel-7.repo kodexplorer4.40.zip nginx.conf
2、创建/opt/dockerfile/kod目录，将所需的软件包和文件放置该目录下
[root@130 ~]# mkdir -p /opt/dockerfile/kod
[root@130 ~]# cd /opt/dockerfile/kod
[root@130 kod]# rz -E
rz waiting to receive.
[root@130 kod]# rz -E
rz waiting to receive.
[root@130 kod]# ls
kodexplorer4.40.zip nginx.txt
3、在该目录下编辑dockerfile，使用基础镜像centos:7
[root@130 kod]# vim Dockerfile
FROM centos:7
ADD Centos-7.repo /etc/yum.repos.d/
ADD epel-7.repo /etc/yum.repos.d/
RUN yum -y install nginx php-fpm php-gd php-mbstring unzip
RUN sed -i '/^user/c user=nginx' /etc/php-fpm.d/www.conf
RUN sed -i '/^group/c group=nginx' /etc/php-fpm.d/www.conf
COPY nginx.conf /etc/nginx/nginx.conf
RUN mkdir /code
WORKDIR /code
COPY kodexplorer4.40.zip .
RUN unzip kodexplorer4.40.zip
RUN chown -R nginx.nginx .
ADD init.sh /init.sh
EXPOSE 80
ENTRYPOINT ["/bin/bash","/init.sh"]
[root@130 kod]# vim init.sh
#!/bin/bash
php-fpm -D
echo "$1" >> /etc/nginx/nginx.conf
nginx -g 'daemon off;'
4、构建镜像kod:v1
[root@130 kod]# mv /root/Centos-7.repo /opt/dockerfile/kod/
[root@130 kod]# mv /root/epel-7.repo /opt/dockerfile/kod/
[root@130 kod]# mv nginx.txt nginx.conf
[root@130 kod]# docker build -t kod:v1 .

5、运行容器，指定映射端口80:80，容器名为自己名字的全拼
[root@130 kod]# docker run -d --name yijunqi -p 80:80 kod:v1 '#jay'
9d2fe7ad3acda4ceb268bb109c053bc054645fc7d4cacb12e3ff98beeb44b7a6

[root@130 kod]# docker exec -it yijunqi /bin/bash
[root@9d2fe7ad3acd code]# tail -3 /etc/nginx/nginx.conf
}
}
#jay
6、使用浏览器访问http://自己docker服务器的ip/index.php，能够实现可道云的使用
