Springboot项目打包成镜像、使用docker-compose启动

1、创建一个boot项目

1、添加依赖

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 https://maven.apache.org/xsd/maven-4.0.0.xsd"><modelVersion>4.0.0</modelVersion><parent><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-parent</artifactId><version>2.5.4</version></parent><groupId>com.wn</groupId><artifactId>demo-compose</artifactId><version>0.0.1-SNAPSHOT</version><name>demo-compose</name><properties><java.version>1.8</java.version></properties><dependencies><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-web</artifactId></dependency><dependency><groupId>mysql</groupId><artifactId>mysql-connector-java</artifactId><version>8.0.31</version></dependency><dependency><groupId>org.projectlombok</groupId><artifactId>lombok</artifactId><optional>true</optional></dependency><dependency><groupId>org.mybatis.spring.boot</groupId><artifactId>mybatis-spring-boot-starter</artifactId><version>2.0.1</version></dependency></dependencies><build><plugins><plugin><groupId>org.springframework.boot</groupId><artifactId>spring-boot-maven-plugin</artifactId><configuration><excludes><exclude><groupId>org.projectlombok</groupId><artifactId>lombok</artifactId></exclude></excludes></configuration></plugin></plugins></build>
</project>

2、entity实体类:

@Data
@AllArgsConstructor
@NoArgsConstructor
public class User {private Integer id;private String name;
}

3、mapper类

import com.wn.entity.User;public interface UserMapper{@Insert("insert into user(id,name) values (#{id},#{name})")void insert(User user);
}

4、controller类

@RestController
public class UserController {@Resourceprivate UserMapper userMapper;@GetMapping("/insert")public String insert() {User user = new User();user.setId(1);user.setName("zhangsan");userMapper.insert(user);return "success";}
}

5、添加yml配置文件

spring:datasource:url: jdbc:mysql://47.94.85.176:3306/docker-compose-bootusername: rootpassword: rootdriver-class-name: com.mysql.cj.jdbc.Driver
server:###端口号port: 8080

2、创建Dockerfile文件

# 基础镜像使用java
FROM openjdk:8
# VOLUME 指定了临时文件目录为/dockercompose/app
VOLUME /dockercompose/app
# 将jar包添加到容器中并更名为docker-compose-boot.jar
ADD compose-boot.jar docker-compose-boot.jar
# 运行jar包
RUN bash -c 'touch /docker-compose-boot.jar'
ENTRYPOINT ["java","-jar","/docker-compose-boot.jar"]
#暴露8080端口
EXPOSE 8080

3、创建一个docker-compose.yml文件

version: "3.0"
services:mysql: # mysql服务image: mysql:5.7restart: alwayscontainer_name: mysql5.7command: --default-authentication-plugin=mysql_native_password # 解决外部无法访问volumes:- ./data:/var/lib/mysql  #挂载目录，持久化存储ports:- "3306:3306"        # 容器端口映射到宿主机的端口environment:MYSQL_ROOT_PASSWORD: 'root'            # root用户的密码，设置为root。MYSQL_ALLOW_EMPTY_PASSWORD: 'no'       # 确保必须设置密码，这里设置为no，意味着不允许空密码。MYSQL_DATABASE: 'docker-compose-boot'  # 创建的默认数据库名，这里设置为docker-compose-bootdocker-compose-boot-web: # 自己单独的springboot项目hostname: scottbuild: ./              # 需要构建的Dockerfile文件ports:- "8080:8080"       # 容器端口映射到宿主机的端口depends_on:           # web服务依赖mysql服务，要等mysql服务先启动- mysql

4、上传到linux进行启动部署

5、启动

 docker-compose -f docker-compose.yml up -d

停止:

docker-compose stop
