1、准备好jdk和tomcat
apache-tomcat-8.5.63.tar.gz
jdk-8u162-linux-x64.tar.gz
注意：
a、jdk和tomcat记得从官网下载，否则制作出来的镜像容易出现不兼容问题。
b、apache-tomcat-8.5.63.tar.gz、jdk-8u162-linux-x64.tar.gz、Dockerfile放在同一目录
2、编写Dockerfile，内容如下：
[root@muze1 local]# cat Dockerfile
FROM centos:latest
MAINTAINER jox
# now add java and tomcat support in the container
ADD jdk-8u162-linux-x64.tar.gz /usr/local/
ADD apache-tomcat-8.5.63.tar.gz /usr/local/
# configuration of java and tomcat ENV
ENV JAVA_HOME /usr/local/jdk1.8.0_162
ENV CLASSPATH $JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar
ENV CATALINA_HOME /usr/local/apache-tomcat-8.5.63
ENV PATH $PATH:$JAVA_HOME/bin:$CATALINA_HOME/lib:$CATALINA_HOME/bin
# container listener port
EXPOSE 8080
# startup web application services by self
CMD /usr/local/apache-tomcat-8.5.63/bin/catalina.sh run
文件目录结果如下：
3、设置Dockerfile权限
chmod 777 Dockerfile
4、开始制作镜像
[root@muze1 local]# docker build -t tomcat8.5.63:v1 /usr/local/
Sending build context to Docker daemon 3.919GB

5、检查当前镜像
[root@muze1 local]# docker images

6、使用制作的镜像运行容器
[root@muze1 local]# docker run -d -p 28080:8080 --name tomcat8_test tomcat8.5.63:v1
43d94b4bc89b2359b6f7d8c082ad351b0ea25c2c1ec6792e3c37e251c03d12e3
