    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

FROM k8s-harbor1.example.com/library/centos-7.5-base:latest

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 .
sleep 2
docker push k8s-harbor1.example.com/library/nginx-base:v1

    执行build.command.sh脚本

    [root@k8s-harbor1 nginx-web1]# ./build-commad.sh
