当前用到的环境是：
Centos 7.5 docker-ce 18.06.1-ce1、先用centos7.5.1804的基础镜像把一些运行需要的环境装好
在/app目录下创建相对应的文件目录

[root@node2 /app/]# mkdir dockerfile/{web/{nginx,tomcat,jdk,apache},system/{centos,ubuntu,redhat}} -pv
[root@node2 /app]# cd dockerfile/system/centos/
[root@node2 /app/dockerfile/system/centos]# mkdir centos-7.5-base
[root@node2 /app/dockerfile/system/centos]# cd centos-7.5-base
创建一个Dockerfile文件

LABEL maintaier “mr.luo <mr.luo@dklwj.com>”
RUN yum install -y vim wget pcre pcre-devel zlib zlib-devel openssl openssl-devel iproute net-tools iotop
创建一个用于直接docker build脚本后续直接执行脚本即可

[root@node2 /app/dockerfile/system/centos/centos-7.5-base]#vim build-command.sh
#!/bin/bash
docker build -t 172.20.7.50/baseimages/centos-base:7.5.1804 .
执行脚本创建新镜像

2、利用制作好的基础环境镜像制作jdk的镜像
从centos-7.5-base退出来在当前目录创建一个jdk1.8的目录.

[root@node2 /app/dockerfile/system/centos/centos-7.5-base]# cd ..
[root@node2 /app/dockerfile/system/centos]# mkdir jdk1.8
[root@node2 /app/dockerfile/system/centos]# cd jdk1.8/
创建Dockerfile

FROM 172.20.7.50/baseimages/centos-base:7.5.1804
LABEL maintainer “mr.luo <mr.luo@dklwj.com>”
ADD jdk-8u162-linux-x64.tar.gz /usr/local/src/
RUN ln -s /usr/local/src/jdk1.8.0_162/ /usr/local/jdk
ADD profile /etc/profile
ENV JAVA_HOME /usr/local/jdk
ENV JRE_HOME $JAVA_HOME/jre
ENV CLASSPATH $JAVA_HOME/lib/:$JRE_HOME/lib/
ENV PATH $PATH:$JAVA_HOME/bin
RUN rm -rf /etc/localtime && ln -snf /usr/share/zoneinfo/Asia/Shanghai /etc/localtime && echo “Asia/Shanghai” > /etc/timezone
上传jdk包到当前目录下：
复制/etc/profile文件到当前目录
在profile最后添加jdk的环境变量

[root@node2 /app/dockerfile/system/centos/jdk1.8]#vim profile
export JAVA_HOME=/usr/local/jdk
export TOMCAT_HOME=/apps/tomcat
export PATH=$JAVA_HOME/bin:$JAVA_HOME/jre/bin:$TOMCAT_HOME/bin:$PATH
export CLASSPATH=.$CLASSPATH:$JAVA_HOME/lib:$JAVA_HOME/jre/lib:$JAVA_HOME/lib/tools.jar
创建docker build的shell脚本

3、做Tomcat的镜像
进入之前建好的/app/dockerfile/web/tomcat下,创建一个tomcat-base目录

[root@node2 ~]# cd /app/dockerfile/web/tomcat
[root@node2 /app/dockerfile/web/tomcat]#mkdir tomcat-base
