[root@localhost compose_lnmt]# mkdir -p /var/www/html/

编写tomcat的dockerfile

[root@localhost compose_lnmt]# mkdir -p tomcat

[root@localhost compose_lnmt]# cd tomcat/

下载tomcat的dockers文件

https://mirrors.bfsu.edu.cn/apache/tomcat/tomcat-8/v8.5.59/bin/apache-tomcat-8.5.59.tar.gz

如果这一步做了下面就不用了

这里上一步做了     就可以跳过

在tomcat目录下放一个apache包

[root@localhost tomcat]# ll

拷贝tomcat数据到容器目录下

 mkdir -p /var/www/tomcat

 cp -a /usr/local/tomcat/webapps/* /var/www/tomcat/

如果没有

 apache-tomcat-8.5.40.tar.gz       把一个apache包解压把文件放到/var/www/tomcat/

[root@localhost tomcat]# ll /var/www/tomcat/
