Docker 安装 Tomcat
方法一、docker pull tomcat
查找 Docker Hub 上的 Tomcat 镜像:
可以通过 Sort by 查看其他版本的 tomcat，默认是最新版本 tomcat:latest。
此外，我们还可以在控制台使用 docker search tomcat 命令来查看可用版本：
1runoob@runoob:~/tomcat$ docker search tomcat 2NAME DESCRIPTION STARS OFFICIAL AUTOMATED 3tomcat Apache Tomcat is an open source implementa... 744 [OK] 4dordoka/tomcat Ubuntu 14.04, Oracle JDK 8 and Tomcat 8 ba... 19 [OK] 5consol/tomcat-7.0 Tomcat 7.0.57, 8080, "admin/admin" 16 [OK] 6consol/tomcat-8.0 Tomcat 8.0.15, 8080, "admin/admin" 14 [OK] 7cloudesire/tomcat Tomcat server, 6/7/8 8 [OK] 8davidcaste/alpine-tomcat Apache Tomcat 7/8 using Oracle Java 7/8 wi... 6 [OK] 9andreptb/tomcat Debian Jessie based image with Apache Tomc... 4 [OK] 10kieker/tomcat 2 [OK] 11fbrx/tomcat Minimal Tomcat image based on Alpine Linux 2 [OK] 12jtech/tomcat Latest Tomcat production distribution on l... 1 [OK]
这里我们拉取官方的镜像：
1runoob@runoob:~/tomcat$ 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。
1runoob@runoob:~/tomcat$ docker images|grep tomcat 2tomcat latest 70f819d3d2d9 7 days ago 335.8 MB
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。
1runoob@runoob:~$ 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。

通过 Dockerfile 创建一个镜像，替换成你自己的名字：
1runoob@runoob:~/tomcat$ docker build -t tomcat .
创建完成后，我们可以在本地的镜像列表里查找到刚刚创建的镜像：
1runoob@runoob:~/tomcat$ docker images|grep tomcat 2tomcat latest 70f819d3d2d9 7 days ago 335.8 MB
使用 tomcat 镜像
运行容器
1runoob@runoob:~/tomcat$ docker run --name tomcat -p 8080:8080 -v $PWD/test:/usr/local/tomcat/webapps/test -d tomcat 2acb33fcb4beb8d7f1ebace6f50f5fc204b1dbe9d524881267aa715c61cf75320 3runoob@runoob:~/tomcat$
命令说明：
**-p 8080:8080：**将主机的 8080 端口映射到容器的 8080 端口。
**-v $PWD/test:/usr/local/tomcat/webapps/test：**将主机中当前目录下的 test 挂载到容器的 /test。
查看容器启动情况
1runoob@runoob:~/tomcat$ docker ps 2CONTAINER ID IMAGE COMMAND ... PORTS NAMES 3acb33fcb4beb tomcat "catalina.sh run" ... 0.0.0.0:8080->8080/tcp tomcat
