八、构建Centos基础镜像：
8.1构建自定义Centos基础镜像：
基于官方的Centos 7.2.1511镜像进行构建，需要下载Centos基础镜像，默认的版本为latest即当前的最新版本，如果要下载指定的版本则需要具体指定版本。
[root@docker-server1 ~]# docker pull centos:7.2.1511
7.2.1511: Pulling from library/centos
f2d1d709a1da: Pull complete
Digest: sha256:7c47810fd05ba380bd607a1ece3b4ad7e67f5906b1b981291987918cb22f6d4d
Status: Downloaded newer image for centos:7.2.1511
或者直接docker load -i centos7.5-docker-image.tar.gz
8.1.1：创建Dockerfile目录：
目录的创建结合业务，创建分层的业务目录。
[root@docker-server1 opt]# mkdir -pv /opt/dockerfile/system/{centos,redtar,ubuntu}
[root@docker-server1 opt]# mkdir -pv /opt/dockerfile/web/{nginx/boss/{nginx-pre,nginx -online},jdk/{jdk7,jdk6},tomcat/boss/{tomcat-pre,tomcat-online}}
8.1.2：创建Dockerfile文件：
Dockefile文件是创建docker 镜像的重要依赖文件，其中定义了镜像的各种需要安装的包、添加的文件等操作，另外要安装业务需求把需要安装的包进行安装。
[root@docker-server1 ~]# cd /opt/dockerfile/system/centos
[root@docker-server1 centos]# vim Dockerfile
#Centos Base Image
FROM centos:7.2.1511
MAINTAINER xxxxx
RUN yum clean all && yum makecache && yum install -y https://mirrors.aliyun.com/epel/epel-release-latest-7.noarch.rpm
RUN yum install -y vim wget tree pcre pcre-devel gcc gcc-c++ zlib zlib-devel openssl openssl-devel net-tools iotop unzip zip iproute ntpdate nfs-utils tcpdump telnet traceroute
8.1.3：执行构建命令：
[root@docker-server1 centos]# docker build -t 192.168.10.210/images/centos7.2.1511-base .
推荐将每个镜像的构建命令写成脚本保存到当前目录，方便后期使用，如：
[root@docker-server1 centos]# cat build-command.sh
#!/bin/bash
docker build -t 192.168.10.210/images/centos7.2.1511-base .
8.2构建nginx业务镜像
8.2.1构建nginx基础镜像
编辑dockerfile脚本
#Nginx Base Image

ADD nginx-1.12.2.tar.gz /usr/local/src
RUN yum -y install gcc gcc-c++ autoconf automake make zlib zlib-devel openssl openssl--devel pcre pcre-devel
RUN cd /usr/local/src/nginx-1.12.2 && ./configure --prefix=/usr/local/nginx && make && make install && ln -sv /usr/local/nginx/sbin/nginx /usr/bin/
RUN useradd nginx -u 1000
ADD filebeat-6.2.4-x86_64.rpm /usr/local/src
RUN yum localinstall -y /usr/local/src/filebeat-6.2.4-x86_64.rpm
RUN rm -rf /usr/local/src/filebeat-6.2.4-x86_64.rpm
编写build-command.sh脚本
#!/bin/bash
docker build -t k8s-harbor1.example.com/library/nginx-base:v1 .

docker push k8s-harbor1.example.com/library/nginx-base:v1
