使用Maven插件构建Docker镜像

使用Maven插件构建Docker镜像 使用Maven插件构建Docker镜像

本文主要介绍如何使用Maven插件将SpringBoot应用打包为Docker镜像，并上传到私有镜像仓库Docker Registry的过程。

1、SpringBoot工程设置 1.1、pom文件

    4.0.0
    
        org.springframework.boot
        spring-boot-starter-parent
        2.1.3.RELEASE
         
    

    com.wnx.mall.tiny
    mall-tiny-docker
    0.0.1-SNAPSHOT
    mall-tiny-docker
    Demo project for Spring Boot

    
        UTF-8
        UTF-8
        1.8
        true
    


    
        
        
            org.springframework.boot
            spring-boot-starter-web
        
        
            org.springframework.boot
            spring-boot-starter-actuator
        
        
            org.springframework.boot
            spring-boot-starter-aop
        
        
            org.springframework.boot
            spring-boot-starter-test
            test
        
        
        
            com.github.pagehelper
            pagehelper-spring-boot-starter
            1.2.10
        
        
        
            com.alibaba
            druid-spring-boot-starter
            1.1.10
        
        
        
            org.mybatis.generator
            mybatis-generator-core
            1.3.7
        
        
        
            mysql
            mysql-connector-java
        
        
        
            io.springfox
            springfox-swagger2
            2.7.0
        
        
            io.springfox
            springfox-swagger-ui
            2.7.0
        
    

    
        
            
                org.springframework.boot
                spring-boot-maven-plugin
            
            
                com.spotify
                docker-maven-plugin
                1.1.0
                
                    
                        build-image
                        package
                        
                            build
                        
                    
                
                
                    mall-tiny/${project.artifactId}:${project.version}
                    http://106.55.226.70:2375
                    java:8
                    ["java", "-jar","/${project.build.finalName}.jar"]
                    
                    
                        
                            /
                            ${project.build.directory}
                            ${project.build.finalName}.jar
                        
                    
                
            
        
    

1.2、application.yaml文件

server:
  port: 8080

spring:
  datasource:
    url: jdbc:mysql://localhost:3306/db?useUnicode=true&characterEncoding=utf-8&serverTimezone=Asia/Shanghai
    username: root
    password: root

mybatis:
  mapper-locations:
    - classpath:mapper/*.xml
    - classpath*:commapper/*.xml

2、Docker设置 2.1、下载Docker

yum install -y yum-utils device-mapper-persistent-data lvm2
yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo
yum install docker-ce
systemctl start docker

2.2、Docker Registry 2.0搭建

docker run -d -p 5000:5000 --restart=always --name registry2 registry:2

2.3、Docker配置修改

• 修改配置文件

vi /usr/lib/systemd/system/docker.service
修改为：ExecStart=/usr/bin/dockerd -H tcp://0.0.0.0:2375 -H unix://var/run/docker.sock

• 支持HTTP上传

echo '{ "insecure-registries":["106.55.226.70:5000"] }'>/etc/docker/daemon.json
systemctl daemon-reload
systemctl stop docker
systemctl start docker

3、执行工作 3.1、MySQL服务启动

• 启动MySQl容器并进入容器

docker run -p 3306:3306 --name mysql 
-v /mydata/mysql/log:/var/log/mysql 
-v /mydata/mysql/data:/var/lib/mysql 
-v /mydata/mysql/conf:/etc/mysql 
-e MYSQL_ROOT_PASSWORD=root  
-d mysql:5.7
docker exec -it mysql /bin/bash

• 让远程连接生效

mysql -uroot -proot
grant all privileges on *.* to 'root'@'%';
create database mall character set utf8;

• window连接导入sql

3.2、Boot服务启动

• 执行会发现，他会先把你的SpringBoot项目打包，再整成镜像上传到你的DockerImages中。

Lifecycle>package

• 运行

docker run -p 8080:8080 --name mall-tiny-docker 
--link mysql:db 
-v /etc/localtime:/etc/localtime 
-v /mydata/app/mall-tiny-docker/logs:/var/logs 
-d mall-tiny/mall-tiny-docker:0.0.1-SNAPSHOT
