用springbootAdmin监控程序制作一个docker镜像

一、搭建springBootAdmin服务

</project>

package monitor;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.context.annotation.Configuration;

import de.codecentric.boot.admin.server.config.EnableAdminServer;

@Configuration
@EnableAutoConfiguration
@EnableAdminServer
public class Application {
    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }
}

application.yml

server:
  port: 8888

二、添加Dockerfile文件

# Docker image for springboot file run
# VERSION 0.0.1
# Author: eangulee
# 基础镜像使用java
FROM java:8
# 作者
MAINTAINER eangulee <eangulee@gmail.com>
# VOLUME 指定了临时文件目录为/tmp。
# 其效果是在主机 /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app.jar
ADD demo-0.0.1-SNAPSHOT.jar app.jar 
# 运行jar包
RUN bash -c 'touch /app.jar'
ENTRYPOINT ["java","-Djava.security.egd=file:/dev/./urandom","-jar","/app.jar"]

三、docker编译镜像

docker build -t springbootdemo4docker .
docker images

 

 四、启动服务

docker run -d -p 8888:8888 --name=springbootadmin springbootdemo4docker
