1.需求
tomcat的容器启动时，可以通过参数命令来决定容器中tomcat的server.xml的访问日志是否开启。

ENTRYPOINT ["catalina.sh","run"]
将dockerfile生成镜像tomcat:wave1.0
启动时：
docker run -it --name mdhtomcat -d -p 80:8080 tomcat:wave1.0 :默认走catalina.sh命令；默认访问日志开启；
docker run -it --name mdhtomcat -d -p 80:8080 tomcat:wave1.0 catalina.sh 1 ：通过传参1，告诉catalina.sh 修改server.xml，该容器不开启访问日志。
3.注意点
ENTRYPOINT和CMD的区别；
sed中如果需要传送特殊字符（$）,需要用 [“”]括住。
往*.sh文件中插入语句时，如果需要使用换行符，则用：[ \n ]
shell中 if 的判断中[ 空格 a == b 空格 ]，其中 == 用于数值，-eq 用于字符串
4.附录一些docker的基本命令
[docker build -t tomcat:wave1.0 . ]
[docker run -it --name mdhtomcat -d -p 80:8080 tomcat:wave1.0]
[docker exec -it mdhtomcat bash ]
[exit]
[docker container stop mdhtomcat]
[docker image ls]
[docker ps -a ]
[docker rm 容器号]
[docker rmi 镜像号]
