Docker 安装 Tomcat

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

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

【记录】linux docker 安装 tomcat

前言:首先linux需要先安装docker,具体步骤可以参考博主之前博客,也可自行百度. 话不多说,开始安装tomcat: 通过docker安装tomcat docker pull tomcat:8.5 原文地址:https://www.cnblogs.com/wbl001/p/11538050.html

Docker安装Tomcat镜像并部署web项目

一.安装Tomcat 1.查找Docker Hub上的tomcat镜像 docker search tomcat 2.拉取官方的镜像 docker pull tomcat 等待下载完毕,需要一些时间. 3.查看docker所有的镜像 docker images 4.启动tomcat镜像 注:前者是外围访问端口:后者是容器内部端口 docker run -d -p 8080:8080 tomcat 注:前者是外围访问端口:后者是容器内部端口 如下命令可后台启动tomcat -d: 后台运行容器,并

docker 安装 tomcat ,dubbo-admin

1.下载tomcat 镜像 docker pull tomcat:8.5.29 2.验证镜像 docker images 3.安装tomcat 默认tomcat端口是8080的http端口映射出来,并且将相应的文件挂载到宿主机中. docker run --name dubbo-admin -p 18080:8080 -v /root/dubbo-admin/tomcat-users.xml:/usr/local/tomcat/conf/tomcat-users.xml -v /root/dub
