1.通过IDEA新建一个普通微服务模块

 建Module   docker_boot

改POM

<?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>2.5.6</version><relativePath/></parent><groupId>com.atguigu.docker</groupId><artifactId>docker_boot</artifactId><version>0.0.1-SNAPSHOT</version><properties><project.build.sourceEncoding>UTF-8</project.build.sourceEncoding><maven.compiler.source>1.8</maven.compiler.source><maven.compiler.target>1.8</maven.compiler.target><junit.version>4.12</junit.version><log4j.version>1.2.17</log4j.version><lombok.version>1.16.18</lombok.version><mysql.version>5.1.47</mysql.version><druid.version>1.1.16</druid.version><mapper.version>4.1.5</mapper.version><mybatis.spring.boot.version>1.3.0</mybatis.spring.boot.version></properties><dependencies><!--SpringBoot通用依赖模块--><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-web</artifactId></dependency><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-actuator</artifactId></dependency><!--test--><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-test</artifactId><scope>test</scope></dependency></dependencies><build><plugins><plugin><groupId>org.springframework.boot</groupId><artifactId>spring-boot-maven-plugin</artifactId></plugin><plugin><groupId>org.apache.maven.plugins</groupId><artifactId>maven-resources-plugin</artifactId><version>3.1.0</version></plugin></plugins></build></project>

写YML

 
server.port=6001

主启动

package com.atguigu.docker;import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;@SpringBootApplication
public class DockerBootApplication
{public static void main(String[] args){SpringApplication.run(DockerBootApplication.class, args);}}

业务类

package com.atguigu.docker.controller;import org.springframework.beans.factory.annotation.Value;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RestController;import java.util.UUID;/*** @auther zzyy* @create 2021-10-25 17:43*/
@RestController
public class OrderController
{@Value("${server.port}")private String port;@RequestMapping("/order/docker")public String helloDocker(){return "hello docker"+"\t"+port+"\t"+ UUID.randomUUID().toString();}@RequestMapping(value ="/order/index",method = RequestMethod.GET)public String index(){return "服务端口号: "+"\t"+port+"\t"+UUID.randomUUID().toString();}
}

2.通过dockerfile发布微服务部署到docker容器

IDEA工具里面搞定微服务jar包

docker_boot-0.0.1-SNAPSHOT.jar

编写Dockerfile 

# 基础镜像使用java
FROM java:8# 作者
MAINTAINER zzyy
# 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zzyy_docker.jar
ADD docker_boot-0.0.1-SNAPSHOT.jar zzyy_docker.jar
# 运行jar包
RUN bash -c 'touch /zzyy_docker.jar'
ENTRYPOINT ["java","-jar","/zzyy_docker.jar"]
#暴露6001端口作为微服务
EXPOSE 6001

将微服务jar包和Dockerfile文件上传到同一个目录下/mydocker

docker build -t zzyy_docker:1.6 .

 

构建镜像 

 

docker build -t zzyy_docker:1.6 .

打包成镜像文件

运行容器

 docker run -d -p 6001:6001 zzyy_docker:1.6

 docker run -d -p 6001:6001 zzyy_docker:1.6
