简单Dockerfile编写实例-编译http安装及挂载文件

先看一下大致的目录结构，一会这些文件都会用到

看一下Dockerfile

FROM centos:7
WORKDIR /usr/local/src
#指定本地tar包和目标容器地址
ADD httpd-2.4.41.tar.gz /usr/local/src 
WORKDIR httpd-2.4.41
#编译安装apache
RUN yum -y install epel-release.noarch && yum makecache fast
RUN yum install -y gcc make apr-devel apr apr-util apr-util-devel pcre-devel
RUN ./configure --prefix=/usr/local/apache2  --enable-mods-shared=most  --enable-so
RUN make
RUN make install
RUN rm -rf /usr/local/src/*
#修改apache配置文件
RUN sed -i 's/#ServerName www.example.com:80/ServerName localhost:80/g' /usr/local/apache2/conf/httpd.conf
#启动apache服务
RUN /usr/local/apache2/bin/httpd
#复制服务启动脚本并设置权限
ADD run.sh /usr/local/sbin/run.sh
RUN chmod 755 /usr/local/sbin/run.sh
#开放80端口
EXPOSE 80
CMD ["/usr/local/sbin/run.sh"]

在当前目录构建镜像

docker build -t my-httpd:v1 .

启动一个容器设置挂载

 docker run -itd --name http01 -p 80:80 -v /dockfile/httpd/htdocs:/usr/local/apache2/htdocs httpd:v1

查看是否成功

测试文件映射
