5.构建镜像
docker build -f Dockerfile -t mytomcat9 .
6.运行容器
docker run -d -p 9090:8080 --name mytomcat9 -v /root/mydocker/tomcat9/test:/usr/local/apache-tomcat-8.5.55/webapps/test -v /root/mydocker/tomcat9/logs:/usr/local/apache-tomcat-8.5.55/logs --privileged=true mytomcat9
7.验证
[root@aaa ~/mydocker/tomcat9]# docker ps
