1.拉取tomcat镜像
docker pull tomcat # 获取tomcat 镜像
2.启动tomcat 容器 （仅用来复制配置文件，复制完即删除此容器）
docker run --name tomcat9 -d -p 8080:8080 tomcat #--name 别名
3.复制tomcat 配置文件到宿主机
docker cp tomcat9 ://usr/local/docker/tomcat9/conf /usr/local/tomcat/conf
docker cp tomcat9 : /usr/local/docker/tomcat9/webapps /usr/local/tomcat/webapps
docker cp tomcat9 :/usr/local/docker/tomcat9/logs /usr/local/tomcat/logs
docker cp:/opt/upload:/opt/upload #这个是把容器的目录复制到宿主机用于文件上传
4、移除容器
docker rm -f tomcat9
5、挂载tomcat9文件到宿主机
docker run -d --name tomcat9 -p 8080:8080 -v /usr/local/docker/tomcat9/conf:/usr/local/tomcat/conf -v /usr/local/docker/tomcat9/webapps:/usr/local/tomcat/webapps -v /usr/local/docker/tomcat9/logs/:/usr/local/tomcat/logs -v /opt/upload:/opt/upload --privileged=true --restart=always tomcat:9
#--name 给你启动的容器起个名字，以后可以使用这个名字启动或者停止容器
#-p 映射端口，将docker宿主机的8080端口和容器的8080口进行绑定
#-v 挂载文件用的，第一个-v 表示将你本地的nginx.conf覆盖你要起启动的容器的nginx.conf文件
#第二个表示将日志文件进行挂载，就是把nginx服务器的日志写到你docker宿主机的/root/docker/nginx/log/下面
#第三个-v 表示的和第一个-v意思一样的。
#-d 表示启动的是哪个镜像
6、查看docker 容器是否启动成功 有出现端口说明成功
docker ps -a
image.png
7、测试
使用curl测试端口号，通过ps 可以查出运行状态以及端口号，测试即可。可以发现出现页面404，说明可以访问了，只是路径出现问题
由于404，肯定是页面出现问题，所以就进去webapps下找
进入正在运行的tomcat9.0容器
docker exec -it tomcat9.0 /bin/bash
进入后可以发现两个重要的webapps以及webapps.dist
在自己tomcat可以发现，下面的东西时全部存在webapps文件夹下的，
点开webapps时发现为空
原来这个tomcat是被docker给阉割了，就是将原本属于webapps下面的全部东西放入到webapps.dist文件下面了
接下来就好办了，可以cp赋值过去，也可以rm移动过去，当然还可以直接删除webapps文件，再将webapps.dist重命名为webapps。这里选择复制
再切换到webapps,就能发现里面有东西了
完成以上步骤，就可以进行最终的测试了
可能需要30s左右，我们就能在浏览器上访问了。一定要用这个外网ip，而不是宿主机ip
