一、背景
之前写了一篇文章：docker-compose部署java项目，每次使用之前需要在本地ide环境打包成jar包，然后上传到linux环境，进入到指定目录，执行docker-compose build,完毕后执行docker-compose up -d,这一路下来麻烦至极，于是想着为啥不能用脚本来执行打包jar、生成并运行docker镜像，于是这篇一键式部署由此而生...
二、环境
# 1. jdk 1.8(不是jre 1.8) [root@192 ~]# java -version java version "1.8.0_202" Java(TM) SE Runtime Environment (build 1.8.0_202-b08) Java HotSpot(TM) 64-Bit Server VM (build 25.202-b08, mixed mode) # 2. maven [root@192 ~]# mvn --version Apache Maven 3.5.4 (1edded0938998edf8bf061f1ceb3cfdeccf443fe; 2018-06-17T14:33:14-04:00) Maven home: /root/apache-maven-3.5.4 Java version: 1.8.0_202, vendor: Oracle Corporation, runtime: /usr/java/jdk1.8.0_202-amd64/jre Default locale: en_US, platform encoding: UTF-8 OS name: "linux", version: "3.10.0-1127.18.2.el7.x86_64", arch: "amd64", family: "unix" # 3. git [root@192 ~]# git --version git version 1.8.3.1 # 4. docker-compose [root@192 ~]# docker-compose -v docker-compose version 1.24.1, build 4667896b
三、具体实现
- 配置ssh，方便拉取仓库中的代码，参考超详细！linux环境git clone探坑录
- 编写dockerFile,参考Docker(四) 通过DockerFile自定义镜像
- 编写docker-compose.yml,参考docker-compose部署java项目
- 编写部署脚本
deployment.sh
#!/usr/bin/env bash # 清理容器 docker system prune -f docker network prune -f # 打包 mvn clean install -Dmaven.test.skip=true # 生成并运行docker images docker-compose -f docker-compose.yml up --build -d
- cd指定目录，拉取代码
git clone xxxxxx.git - cd进入到脚本目录，并赋权限，不然无法执行
[root@192 ~]# cd /root/test/car_wash_api/scripts/ [root@192 scripts]# ll total 4 -rwxrwxrwx. 1 root root 230 Dec 10 14:31 deployment.sh [root@192 scripts]# chmod 777 deployment.sh
- cd到项目根目录，执行脚本

四、补充说明
- 安装环境的时候可能会碰到很多的坑，放心，我已经帮您趟过了，有问题可以参考这篇centos 7 yum安装失败(HTTP Error 404 - Not Found)的解决方法。
- 如果有需要，可以访问源码地址
