eureka-server項目application-test.yml的配置文件

spring:
  application:
    name: eureka-server
server:
  port: 8761

eureka:
  instance:
    hostname: localhost
  client:
    register-with-eureka: false
    fetch-registry: false
    service-url:
      defaultZone: http://${eureka.instance.hostname}:${server.port}/eureka/,${ADDITIONAL_EUREKA_SERVER_LIST}

ADDITIONAL_EUREKA_SERVER_LIST 是定義的環(huán)境變量涣觉，在容器啟動時傳入

eureka-server的docker編排

version: '3.3'
services:
  eureka-server1:
    image: 172.16.10.2:5000/test/eureka-server:latest 
    networks:
      test:
        aliases:
          - eureka-server
    ports:
      - "8761:8761"
    environment:
      - ADDITIONAL_EUREKA_SERVER_LIST=http://eureka-server2:8761/eureka/,http://eureka-server3:8761/eureka/
      - "SPRING_PROFILES_ACTIVE=test"

  eureka-server2:
    image: 172.16.10.2:5000/test/eureka-server:latest
    networks:
      test:
        aliases:
          - eureka-server
    ports:
      - "8762:8761"
    environment:
      - ADDITIONAL_EUREKA_SERVER_LIST=http://eureka-server1:8761/eureka/,http://eureka-server3:8761/eureka/
      - "SPRING_PROFILES_ACTIVE=test"

  eureka-server3:
    image: 172.16.10.2:5000/test/eureka-server:latest
    networks:
      test:
        aliases:
          - eureka-server
    ports:
      - "8763:8761"
    environment:
      - ADDITIONAL_EUREKA_SERVER_LIST=http://eureka-server1:8761/eureka/,http://eureka-server2:8761/eureka/
      - "SPRING_PROFILES_ACTIVE=test"

networks:
  test:
    external: true

image 是用的自建的鏡像庫 SPRING_PROFILES_ACTIVE是在dockerfile中的變量，為了指定啟動環(huán)境庄萎，如果你的配置文件不區(qū)分環(huán)境迹恐，可以去掉這一行"- SPRING_PROFILES_ACTIVE=test"這里的networks需要提前創(chuàng)建。
