新建docker目錄
新建docker-compose.yml

version: "3.1"
services:
  cbj-admin:
      restart: always
      image: 192.168.0.39:5000/cbj-admin
      container_name: cbj-admin
      ports:
        - 8084:8084

新建Dockerfile

FROM openjdk:8-jre

MAINTAINER yuyingliang <[e-mail]>

RUN mkdir /app

COPY cbj-admin-1.0.0-SNAPSHOT.jar /app/app.jar

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


EXPOSE 8084

新建src/main/java
新建com.funtl.cbj.admin包
新建AdminApplication啓動類

package com.funtl.cbj.admin;

import de.codecentric.boot.admin.server.config.EnableAdminServer;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.netflix.eureka.EnableEurekaClient;

@SpringBootApplication
@EnableEurekaClient
@EnableAdminServer
public class AdminApplication {
    public static void main(String[] args) {
        SpringApplication.run(AdminApplication.class, args);
    }


}

在main下新建resources目錄
新建bootstrap.yml

  cloud:
    config:
      uri: http://localhost:8888
      name: cbj-admin
      label: master
      profile: dev

bootstrap-test.yml
