用dockerfile做一个apache的镜像

• 创建存放apache服务Dockerfile文件的目录
• 上传apr、apr-util、httpd源码包
• 编写Dockerfile文件
• 构建镜像
• 查看镜像
• 基于新镜像创建容器
• 访问网页

创建存放apache服务Dockerfile文件的目录

[root@localhost ~]# mkdir apache
[root@localhost ~]# cd apache/
[root@localhost apache]# mkdir files

上传apr、apr-util、httpd源码包

[root@localhost apache]# cd files/
[root@localhost files]# ls
apr-1.7.0.tar.gz  apr-util-1.6.1.tar.gz  httpd-2.4.48.tar.gz

编写Dockerfile文件

[root@localhost apache]# vim Dockerfile
# 基础镜像

ADD files/* /usr/local

# 切换当前目录
