项目运行测试

准备数据库

准备Redis

启动项目成功

浏览器测试

http://localhost:6001/user/find/88

访问swagger页面进行测试

http://localhost:6001/swagger-ui.html

测试成功

查询数据库插入成功

Redis插入成功

使用Docker部署

docker run -p 3307:3306 --name mysql57 --privileged=true -v /mydata/mysql-master/log:/var/log/mysql -v /mydata/mysql-master/data:/var/lib/mysql -v /mydata/mysql-master/conf:/etc/mysql -e MYSQL_ROOT_PASSWORD=root  -d mysql:5.7

进入容器bash

docker exec -it mysql57 /bin/bash

创建数据库

mysql -uroot -p

create database docker;

CREATE TABLE `t_user` (
  `id` int(10) unsigned NOT NULL AUTO_INCREMENT,
  `username` varchar(50) NOT NULL DEFAULT '' COMMENT '用户名',
  `password` varchar(50) NOT NULL DEFAULT '' COMMENT '密码',
  `sex` tinyint(4) NOT NULL DEFAULT '0' COMMENT '性别 0=女 1=男 ',
  `deleted` tinyint(4) unsigned NOT NULL DEFAULT '0' COMMENT '删除标志，默认0不删除，1删除',
  `update_time` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP COMMENT '更新时间',
  `create_time` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP COMMENT '创建时间',
  PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=1 DEFAULT CHARSET=utf8 COMMENT='用户表';

use docker;

单独的redis容器实例

docker run  -p 6399:6379 --name redis608 --privileged=true -v /app/redis/redis.conf:/etc/redis/redis.conf -v /app/redis/data:/data -d redis:6.0.8 redis-server /etc/redis/redis.conf

修改application.properties

打包上传到Linux虚拟机

编写DockerFile文件

# 基础镜像使用java
FROM java:8
# 作者
MAINTAINER zk
# VOLUME 指定临时文件目录为/tmp，在主机/var/lib/docker目录下创建了一个临时文件并链接到容器的/tmp
VOLUME /tmp
# 将jar包添加到容器中并更名为zk_docker.jar
ADD DockerDemo-1.0-SNAPSHOT.jar zk_docker.jar
# 运行jar包
RUN bash -c 'touch /zk_docker.jar'
ENTRYPOINT ["java","-jar","/zk_docker.jar"]
#暴露6001端口作为微服务
EXPOSE 6001

编译dockerFile文件并指定打包成镜像指定版本

docker build -f docker_demo -t zk_docker:1.8 .

查询镜像

docker images

# 对外暴露端口
docker run -d -p 6001:6001 容器ID

docker ps

运行成功！

进入浏览器测试

http://ip:6001/user/find/88

http://ip:6001/swagger-ui.html

使用Compose部署

编写docker-compose.yml文件

version: "3"

services:
  microService:
    image: zk_docker:1.9
    container_name: ms01
    ports:
      - "6001:6001"
    volumes:
      - /app/microService:/data
    networks:
      - zk_net
    depends_on:
      - redis
      - mysql

  redis:
    image: redis:6.0.8
    ports:
      - "6399:6379"
    volumes:
      - /app/redis/redis.conf:/etc/redis/redis.conf
      - /app/redis/data:/data
    networks:
      - zk_net
    command: redis-server /etc/redis/redis.conf

  mysql:
    image: mysql:5.7
    container_name: mysql
    environment:
      MYSQL_ROOT_PASSWORD: 'root'
      MYSQL_ALLOW_EMPTY_PASSWORD: 'no'
      MYSQL_DATABASE: 'docker'
      MYSQL_USER: 'zzkk'
      MYSQL_PASSWORD: 'zzkk123'
    ports:
      - "3307:3306"
    volumes:
      - /app/mysql/db:/var/lib/mysql
      - /app/mysql/conf/my.cnf:/etc/my.cnf
      - /app/mysql/init:/docker-entrypoint-initdb.d
    networks:
      - zk_net
    command:
      --default-authentication-plugin=mysql_native_password
      --character-set-server=utf8mb4
      --collation-server=utf8mb4_general_ci
networks:
  zk_net:

修改application.properties

新建一个文件夹mydocker

mkdir docker 

cd docker

docker build -f docker_demo -t zk_docker:1.9 .

docker-compose up -d

确保3个文件在同一个文件夹里

修改dokcerfile文件

现在我们有2个版本，一个是不使用DockerCompose部署，一个是使用DockerCompose部署的

一键部署3个项目起来

进入mysql容器实例并新建库docker+新建表t_user

docker exec -it 容器实例id /bin/bash

mysql -uroot -p

create database docker;

use docker;

CREATE TABLE `t_user` (
  `id` INT(10) UNSIGNED NOT NULL AUTO_INCREMENT,
  `username` VARCHAR(50) NOT NULL DEFAULT '' COMMENT '用户名',
  `password` VARCHAR(50) NOT NULL DEFAULT '' COMMENT '密码',
  `sex` TINYINT(4) NOT NULL DEFAULT '0' COMMENT '性别 0=女 1=男 ',
  `deleted` TINYINT(4) UNSIGNED NOT NULL DEFAULT '0' COMMENT '删除标志，默认0不删除，1删除',
  `update_time` TIMESTAMP NOT NULL DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP COMMENT '更新时间',
  `create_time` TIMESTAMP NOT NULL DEFAULT CURRENT_TIMESTAMP COMMENT '创建时间',
  PRIMARY KEY (`id`)
) ENGINE=INNODB AUTO_INCREMENT=1 DEFAULT CHARSET=utf8mb4 COMMENT='用户表';

测试

成功查询数据

查看日志成功插入数据

docker-compose logs

Redis 6399端口也连接成功

进入mysql容器查看数据

进入redis容器查看数据

至此Docker部署SpringBoot的流程已经完成，以后只要编写一个DockerFile和docker-compose.yml就可以实现一键部署！
