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                   [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]

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

runoob@runoob:~/tomcat$ docker ps CONTAINER ID    IMAGE     COMMAND               ... PORTS                    NAMESacb33fcb4beb    tomcat    "catalina.sh run"     ... 0.0.0.0:8080->8080/tcp   tomcat
