1、準備鏡像文件tomcat壓縮包，jdk的壓縮包
tomcat鏈接：https://pan.baidu.com/s/1Xpecb-BSGR2sdxSL7FDtBw?pwd=1234?
提取碼：1234
jdk鏈接：https://pan.baidu.com/s/1mQHInn27j1I9uuuicBsyAA?pwd=1234?
提取碼：1234
2、編寫dockerfile文件，官方命名 Dockerfile? ，build會自動尋找這個文件，就不需要 -f 指定了
FROM centos:7
MAINTAINER wq<123456@qq.com>COPY readme.txt /usr/local/readme.txtADD jdk-8u131-linux-x64.tar.gz /usr/local/
ADD apache-tomcat-9.0.75.tar.gz /usr/local/RUN yum install -y vim net-toolsENV MYPATH /usr/local
