1.准备一台机子，准备源，下载docker-ce


vi /etc/yum.repo.d/Centos-7.repo  加入以下内容

安装docker
yum -y install docker-ce

2.创建一个dockerfile执行目录，使用dockerfile编写apache镜像。

#进入dockerfile 编写
FROM centos:7    #要看你现在docker images 里面有没有centos7镜像，
RUN yum -y install httpd -y
VOLUME ["/var/www/html"]  #卷
EXPOSE 80  #端口暴露
CMD ["/usr/sbin/httpd","-DFOREGROUND"]  #启动httpd

3.构建镜像，并运行容器（使用端口）。

#执行dockerfile编写的命令
docker build -t httpd:v1 .

#运行httpd端口暴露
docker run -d -p 8888:80 --name httpd httpd:v1

#使用macvlan指定ip，先创建macvlan
docker network create -d macvlan --subnet 192.168.10.0/24 --gateway 192.168.10.2 -o parent=ens33 macvlan2

#使用macvlan运行，并指定ip
docker run -d --net macvlan --ip 192.168.10.86 --name httpd2 httpd:v1

构建镜像成功。

启动镜像成功。

4.浏览器访问：

端口暴露访问：192.168.10.202:8888

ip访问：192.168.10.86（macvlan）

5. 创建主页和分页，先找到数据卷的位置

#找查数据卷位置  （中间的89是容器的id简写）
 docker inspect 89 | grep Sou

#进入数据卷位置  
cd 
/var/lib/docker/volumes/b5275e14935d153586686436df235d85a1cb87f7926392f5d1028906648c5c04/_data

#创建一个主页文件
vi index.html 写入

hallo word

#在创建一个 yang.html 写入
