-it         #  是-i  和 -t的简写， 表示以交互式的方式运行容器，加上-d表示后台运行，这里为了截图输出启动日志我用了-it，也可以用-d，再用"docker logs 容器名"命令输出日志

--rm        #当容器被停止时自动删除容器

-p 8888:80  #80是为容器中的tomcat设置的端口， 这里表示将80映射到宿主机8888端口， 如果只写-p 80  容器会随机取值32768~61000中较大的端口号来映射到80端口上

-v          # 将tomcat中的usr/local/tomcat/webapps目录映射到宿主机当前目录的webapps目录，后面更新jar包直接扔到被映射的宿主机目录中即可

tomcat:8.0  # 镜像名：tag标签

 # docker run -it --rm -p : -v $PWD/webapps:/usr/local/tomcat/webapps tomcat:8.0
