docker-compose 完整打包发布, 多服务,多节点SPRING CLOUD ,EUREKA 集群

标签：aseinvoiceetcblerouteasioutipalease

这里不再使用 端口映射的方式,因为不同主机上,Feign 根据 docker hostname访问会有问题.

把打包的好jar copy到docker镜像里

有几个服务,就复制几个dockerfile

Dockerfile

FROM registry.cn-hangzhou.aliyuncs.com/laizhenwei/jre:8u144

COPY jar /usr/local

RUN cp /usr/share/zoneinfo/Asia/Shanghai /etc/localtime && \\
echo ‘Asia/Shanghai‘ >/etc/timezone

开启两个eureka,互相注册

开启两个api服务,

开启两个app服务.

开启一个zuul路由服务

应用application.yml,注册到两个eureka

eureka:
instance:
appname: app
instance-id: ${spring.cloud.client.ipAddress}:${server.port}
#续约更新时间间隔
lease-renewal-interval-in-seconds: 10
#续约到期时间
lease-expiration-duration-in-seconds: 30
client:
serviceUrl:
defaultZone: http://username:password@eureka1:8000/eureka/,http://username:password@eureka2:8001/eureka/

eureka application.yml

eureka:
instance:
hostname: localhost
other-port: 8001
other-hostname: backup
appname: eureka-server
instance-id: ${spring.cloud.client.ipAddress}:${server.port}
lease-expiration-duration-in-seconds: 5
server:
#关闭自我保护
enable-self-preservation: false
#5秒清理一次
eviction-interval-timer-in-ms: 5
client:
register-with-eureka: true
fetch-registry: true
service-url:
defaultZone: http://username:password@${eureka.instance.other-hostname}:${eureka.instance.other-port}/eureka/

输入命令:docker-compose up –build -d
