Docker 安裝 Tomcat
方法一、docker pull tomcat
查找?Docker Hub?上的 Tomcat 鏡像:
可以通過 Sort by 查看其他版本的 tomcat，默認是最新版本?tomcat:latest。
此外，我們還可以用 docker search tomcat 命令來查看可用版本：
runoob@runoob:~/tomcat$ docker search tomcat NAME DESCRIPTION STARS OFFICIAL AUTOMATED tomcat Apache Tomcat is an open source implementa... 744 [OK] dordoka/tomcat Ubuntu 14.04, Oracle JDK 8 and Tomcat 8 ba... 19 [OK] consol/tomcat-7.0 Tomcat 7.0.57, 8080, "admin/admin" 16 [OK] consol/tomcat-8.0 Tomcat 8.0.15, 8080, "admin/admin" 14 [OK] cloudesire/tomcat Tomcat server, 6/7/8 8 [OK] davidcaste/alpine-tomcat Apache Tomcat 7/8 using Oracle Java 7/8 wi... 6 [OK] andreptb/tomcat Debian Jessie based image with Apache Tomc... 4 [OK] kieker/tomcat 2 [OK] fbrx/tomcat Minimal Tomcat image based on Alpine Linux 2 [OK] jtech/tomcat Latest Tomcat production distribution on l... 1 [OK]
這里我們拉取官方的鏡像：
runoob@runoob:~/tomcat$ docker pull tomcat
等待下載完成后，我們就可以在本地鏡像列表里查到 REPOSITORY 為 tomcat 的鏡像。
runoob@runoob:~/tomcat$ docker images|grep tomcat tomcat latest 70f819d3d2d9 7 days ago 335.8 MB
方法二、通過 Dockerfile 構建
創建Dockerfile
首先，創建目錄tomcat,用于存放后面的相關東西。
runoob@runoob:~$ mkdir -p ~/tomcat/webapps ~/tomcat/logs ~/tomcat/conf
webapps 目錄將映射為 tomcat 容器配置的應用程序目錄。
logs 目錄將映射為 tomcat 容器的日志目錄。
conf 目錄里的配置文件將映射為 tomcat 容器的配置文件。
進入創建的 tomcat 目錄，創建 Dockerfile。

通過 Dockerfile 創建一個鏡像，替換成你自己的名字：
runoob@runoob:~/tomcat$ docker build -t tomcat .
創建完成后，我們可以在本地的鏡像列表里查找到剛剛創建的鏡像：
runoob@runoob:~/tomcat$ docker images|grep tomcat tomcat latest 70f819d3d2d9 7 days ago 335.8 MB
使用 tomcat 鏡像
運行容器
runoob@runoob:~/tomcat$ docker run --name tomcat -p 8080:8080 -v $PWD/test:/usr/local/tomcat/webapps/test -d tomcat acb33fcb4beb8d7f1ebace6f50f5fc204b1dbe9d524881267aa715c61cf75320 runoob@runoob:~/tomcat$
命令說明：
-p 8080:8080：將主機的 8080 端口映射到容器的 8080 端口。
-v $PWD/test:/usr/local/tomcat/webapps/test：將主機中當前目錄下的 test 掛載到容器的 /test。
查看容器啟動情況
runoob@runoob:~/tomcat$ docker ps CONTAINER ID IMAGE COMMAND ... PORTS NAMES acb33fcb4beb tomcat "catalina.sh run" ... 0.0.0.0:8080->8080/tcp tomcat
