Jhipster Registry（Eureka Server） Docker双向联通与高可用部

使用Compose来编排这个Eureka Server集群：

peer1配置：

server:
    port: 8761

eureka:
    instance:
        hostname: eureka-peer-1
    server:
        # see discussion about enable-self-preservation:
        # https://github.com/jhipster/generator-jhipster/issues/3654
        enable-self-preservation: false
        registry-sync-retry-wait-ms: 500
        a-sgcache-expiry-timeout-ms: 60000
        eviction-interval-timer-in-ms: 30000
        peer-eureka-nodes-update-interval-ms: 30000
        renewal-threshold-update-interval-ms: 15000
    client:
        fetch-registry: true
        register-with-eureka: true
        service-url:
            defaultZone: http://admin:${spring.security.user.password:admin}@eureka-peer-2:8762/eureka/

peer2配置：

server:
    port: 8762

eureka:
    instance:
        hostname: eureka-peer-2
    server:
        # see discussion about enable-self-preservation:
        # https://github.com/jhipster/generator-jhipster/issues/3654
        enable-self-preservation: false
        registry-sync-retry-wait-ms: 500
        a-sgcache-expiry-timeout-ms: 60000
        eviction-interval-timer-in-ms: 30000
        peer-eureka-nodes-update-interval-ms: 30000
        renewal-threshold-update-interval-ms: 15000
    client:
        fetch-registry: true
        register-with-eureka: true
        service-url:
            defaultZone: http://admin:${spring.security.user.password:admin}@eureka-peer-1:8761/eureka/

构建Image

使用官方的DockerFile：

FROM openjdk:8-jre-alpine

ENV SPRING_OUTPUT_ANSI_ENABLED=ALWAYS 
    JAVA_OPTS="" 
    JHIPSTER_SLEEP=0

VOLUME /tmp
EXPOSE 8761
CMD echo "The application will start in ${JHIPSTER_SLEEP}s..." && 
    sleep ${JHIPSTER_SLEEP} && 
    java ${JAVA_OPTS} -Djava.security.egd=file:/dev/./urandom -jar /app.war

# add directly the war
ADD *.war /app.war

构建Image并push到registry，这里是192.168.86.8:5000/registry-dev

编写compose文件：

version: "3" 
services:
  eureka-peer-1 :
    image: 192.168.86.8:5000/registry-dev:latest
    links:
      - eureka-peer-2
    ports:
      - "8761:8761"
    environment:
      spring.profiles.active: oauth2,peer1,swagger
    entrypoint:
      - java
      - -Dspring.profiles.active=oauth2,swagger
      - -Djava.security.egd=file:/dev/./urandom
      - -jar
      - /app.war
  eureka-peer-2:
    image: 192.168.86.8:5000/registry-dev:latest
    links:
      - eureka-peer-1
    expose:
      - "8762"
    ports:
      - "8762:8762"
    environment:
      spring.profiles.active: oauth2,peer2,swagger
      - -Djava.security.egd=file:/dev/./urandom
      - -jar
      - /app.war

启动即可。
