docker运行springboot实例

摘要：中使用打包直接在的时候执行指定了的名称为指定了镜像名为实例文件在文件夹下面建立的内容也可以直接在中用设置定义存储位置定义应用名称每隔小时分割为表示以分为边界添加依赖镜像查看日志工程

        
        app
        
            
                org.springframework.boot
                spring-boot-maven-plugin
            

            
            
                com.spotify
                docker-maven-plugin
                0.2.3
                
                    ${project.name}:${project.version}
                    
                        ${project.version}
                        latest
                    
                    ${project.basedir}/src/main/docker
                    false
                    
                        
                            ${project.build.directory}
                            ${project.build.finalName}.jar
                        
                    
                

                
                
                    
                        
                        
                            
                        
                    
                
            
        
    

指定了jar的名称为app

指定了docker镜像名为${project.name}:${project.version}

@SpringBootApplication
@RestController
public class SpringbootDockerDemoApplication {

    public static void main(String[] args) {
        SpringApplication.run(SpringbootDockerDemoApplication.class, args);
    }

    @RequestMapping("/")
    public String index(){
        return "this is index";
    }
}

在src/main/docker文件夹下面建立Dockerfile

FROM java:8
# time zone
RUN echo "Asia/Chongqing" > /etc/timezone && dpkg-reconfigure -f noninteractive tzdata
RUN mkdir /app
RUN mkdir /app/logs
ADD app.jar /app/app.jar
ADD runboot.sh /app/
RUN bash -c "touch /app/app.jar"
WORKDIR /app
RUN chmod a+x runboot.sh
CMD /app/runboot.sh

runboot.sh的内容

sleep 90
java -Djava.security.egd=file:/dev/./urandom -jar /app/app.jar

也可以直接在Dockerfile中用ENTRYPOINT

ENTRYPOINT ["java","-Djava.security.egd=file:/dev/./urandom","-jar","app.jar"]

    
        
        /app/logs
        
        springboot-docker-demo
    
    
        
            
        
        
            
            
                
                
            
        

        
        
            
            
        
    
    
        
            
        
    

添加依赖

            org.springframework.boot
            spring-boot-starter-web
            
                
                
                    org.springframework.boot
                    spring-boot-starter-logging
                
            
        
        
            org.springframework.boot
            spring-boot-starter-log4j2
        

mvn package -Dskip.test=true
mvn docker:build
docker run -d -p 8080:8080 -v /tmp/docker-logs:/app/logs springboot-docker-demo
http://{docker-machine-ip}:8080/

docker-machine ssh default
cd /tmp/docker-logs
tail -f springboot-docker-demo.log
