先将jdk,tomcat和一个Dockerfile放到同一个文件夹下
编辑Dockerfile
FROM centos

#启动时运行tomcat
# ENTRYPOINT ["/usr/local/apache-tomcat-9.0.8/bin/startup.sh" ]

CMD /usr/local/apache-tomcat-9.0.8/bin/startup.sh && tail -F /usr/local/apache-tomcat-9.0.8/bin/logs/catalina.out将Dockerfile建立(build)成镜像
docker build -t mytomcat .运行mytomcat镜像,并添加数据卷两个数据卷,一个共享ROOT文件夹,一个查看日志
docker run -d -p 8888:8080 --name mytomcat -v /mytomcat/webapps/ROOT:/usr/local/tomcat/webapps/ROOT -v /mytomcat/logs:/usr/local/tomcat/logs --privileged=true mytomcat
