2.下载tomcat
docker pull tomcat

[root@VM-8-4-centos ~]# docker pull tomcat

docker.io/library/tomcat:latest

 3.创建容器并启动 

 docker run -d -p 8082:8080 --name Tomcat01 tomcat

现在访问一下主机的8082端口：

发现确实已经启动了tomcat，但是没有页面

这是因为从阿里云上下载的镜像是最小的镜像，把不必要的东西都剔除掉了

接下来进入tomcat内部查看一下

[root@VM-8-4-centos ~]# docker exec -it Tomcat01 /bin/bash
root@73d65ea43f67:/usr/local/tomcat# ls
BUILDING.txt  CONTRIBUTING.md  LICENSE    NOTICE    README.md  RELEASE-NOTES  RUNNING.txt  bin  conf  lib  logs  native-jni-lib  temp  webapps  webapps.dist  work
root@73d65ea43f67:/usr/local/tomcat# cd webapps
root@73d65ea43f67:/usr/local/tomcat/webapps# ls
root@73d65ea43f67:/usr/local/tomcat/webapps# cd ../webapps.dist
root@73d65ea43f67:/usr/local/tomcat/webapps.dist# ls
ROOT  docs  examples  host-manager  manager
root@73d65ea43f67:/usr/local/tomcat/webapps.dist# cp -r * ../webapps
root@73d65ea43f67:/usr/local/tomcat/webapps.dist# cd ../webapps
root@73d65ea43f67:/usr/local/tomcat/webapps# ls
ROOT  docs  examples  host-manager  manager

上述命令把webapps.dist目录下的网站复制到了webapps目录下，现在应该能够访问tomcat页面了：

 没有问题。
