Build image

Use the official 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

Build the image and push it to the registry. Here is 192.168 86.8:5000/registry-dev

Write a compose file:

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
