说明：tomcat的端口是8080。随机分配一个宿主机的端口，然后映射到tomcat容器的8080端口

2. 查看tomcat容器的宿主机端口

[root@docker ~]# docker ps 
CONTAINER ID   IMAGE     COMMAND             CREATED              STATUS              PORTS                                         NAMES
3042d1526334   tomcat    "catalina.sh run"   About a minute ago   Up About a minute   0.0.0.0:49153->8080/tcp, :::49153->8080/tcp   festive_mayer
[root@docker ~]#

3. 访问tomcat页面

访问http://192.168.23.31:49153，如下所示

4. tomcat webapps目录修改

因为webapps目录为空，用浏览器访问会报404。进入容器删除webapps，然后将webapps-dist重命名为webapps

[root@docker ~]# docker exec -it 3042d1526334 bash
root@3042d1526334:/usr/local/tomcat# 
root@3042d1526334:/usr/local/tomcat# ls webapps
root@3042d1526334:/usr/local/tomcat# 
root@3042d1526334:/usr/local/tomcat# rm webapps -rf
root@3042d1526334:/usr/local/tomcat# 
root@3042d1526334:/usr/local/tomcat# mv webapps.dist webapps
root@3042d1526334:/usr/local/tomcat# 

再次访问tomcat页面，如下所示
