Docker 安装 Tomcat

Posted 2022-03-01 miracle-luna

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

ENV PATH $CATALINA_HOME/bin:$PATH
RUN mkdir -p "$CATALINA_HOME"
WORKDIR $CATALINA_HOME

ENV LD_LIBRARY_PATH $LD_LIBRARY_PATH:+$LD_LIBRARY_PATH:$TOMCAT_NATIVE_LIBDIR

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
