Docker 安装 Tomcat方法一、docker pull tomcat
原文 https://www.runoob.com/docker/docker-install-tomcat.html

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,我们还可以用 docker search tomcat 命令来查看可用版本:
runoob@runoob:~/tomcat$ docker search tomcatNAME                       DESCRIPTION                                     STARS     OFFICIAL   AUTOMATEDtomcat                     Apache Tomcat is an open source implementa...   744       [OK       dordoka/tomcat             Ubuntu 14.04, Oracle JDK 8 and Tomcat 8 ba...   19                   [OKconsol/tomcat-7.0          Tomcat 7.0.57, 8080, "admin/admin"              16                   [OKconsol/tomcat-8.0          Tomcat 8.0.15, 8080, "admin/admin"              14                   [OKcloudesire/tomcat          Tomcat server, 6/7/8                            8                    [OKdavidcaste/alpine-tomcat   Apache Tomcat 7/8 using Oracle Java 7/8 wi...   6                    [OKandreptb/tomcat            Debian Jessie based image with Apache Tomc...   4                    [OKkieker/tomcat                                                              2                    [OKfbrx/tomcat                Minimal Tomcat image based on Alpine Linux      2                    [OKjtech/tomcat               Latest Tomcat production distribution on l...   1                    [OK
这里我们拉取官方的镜像:
runoob@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。
runoob@runoob:~/tomcat$ docker images|grep tomcattomcat              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。
runoob@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:
runoob@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:
runoob@runoob:~/tomcat$ docker images|grep tomcattomcat              latest              70f819d3d2d9        7 days ago          335.8 MB
使用 tomcat 镜像运行容器runoob@runoob:~/tomcat$ docker run --name tomcat -p 8080:8080 -v $PWD/test:/usr/local/tomcat/webapps/test -d tomcat  acb33fcb4beb8d7f1ebace6f50f5fc204b1dbe9d524881267aa715c61cf75320runoob@runoob:~/tomcat$
命令说明:
-p 8080:8080:将容器的 8080 端口映射到主机的 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
