Dockerfile构建httpd镜像（yum方式）

1、建立工作目录

[root@docker ~]# mkdir httpd

[root@docker ~]# cd httpd

2、编写Dockerfile文件

[root@docker httpd]# vim Dockerfile

FROM centos:7
MAINTAINER Crushlinux <crushlinux@163.com>

RUN yum -y install httpd
RUN echo "crushlinux" >/var/www/html/index.html
RUN ln -sf /usr/share/zoneinfo/Asia/Shanghai /etc/localtime

EXPOSE 80
CMD ["httpd","-DFOREGROUND"]

3、构建镜像

[root@docker httpd]# docker build -t httpd:new .

[root@docker httpd]# docker images httpd

4、测试容器

[root@docker httpd]# docker run -d -p 8001:80 --name httpd-test --restart=always httpd:new
