Docker 安装 Tomcat
方法一、docker pull tomcat
查找 Docker Hub 上的 tomcat 镜像：
docker search tomcat
这里我们拉取官方最新版本的 tomcat 镜像：
docker pull tomcat
等待下载完成后，我们就可以在本地镜像列表里查到 REPOSITORY 为 tomcat 的镜像：
docker images|grep tomcat
方法二、通过 Dockerfile 构建
创建 Dockerfile
首先，创建目录 tomcat，用于存放后面的相关东西：
mkdir -p ./tomcat/webapps ./tomcat/logs ./tomcat/conf
webapps 目录将映射为 tomcat 容器配置的应用程序目录
logs 目录将映射为 tomcat 容器的日志目录
conf 目录里的配置文件将映射为 tomcat 容器的配置文件
进入创建的 tomcat 目录，创建 Dockerfile

EXPOSE 8080
CMD ["catalina.sh", "run"]
通过Dockerfile创建一个镜像，替换成你自己的名字：
docker build -t tomcat .
使用tomcat镜像
运行镜像，生成容器
使用 docker run 命令运行镜像：
docker run --name my-tomcat -p 80801:8080 -v $PWD/webapps/test:/usr/local/tomcat/webapps/test -d tomcat
命令说明
-p 8080:8080：将主机的 8081 端口映射到容器的 8080 端口
-v $PWD/webapps/test:/usr/local/tomcat/webapps/test：将主机中当前目录下的 /webapps/test 挂载到容器的/test
查看容器启动情况：
查看容器中 tomcat 的启动日志：
docker logs -f my-tomcat
通过浏览器访问 tomcat：
URL：http://个人机器IP:8081
