六、Docker安装微服务

一、编译所有的所需jar包

二、上传到服务器*

三、编写Docerfile

FROM java:8
ADD registry-center-1.0-SNAPSHOT.jar registry-center-1.0-SNAPSHOT.jar
ENTRYPOINT ["java","-jar","registry-center-1.0-SNAPSHOT.jar"]

ENTRYPOINT 表示，容器启动执行命令

五、启动注册中心容器

1）修改application.yml配置文件

## 启动顺序： #1

spring:
  application:
    name: eureka-server
  profiles:
    active: dev

server:
  port: 20000

eureka:
  client:
    fetch-registry: false
    register-with-eureka: false
  instance:
    ## 将localhost指向本机（host文件）
    hostname: localhost

2）build
build会先从公网上下载需要的镜像，然后再build

docker build -t myregistry .

3）运行容器

docker run -d -p 20000:20000 --name myregistry myregistry

六、启动配置中心容器

1）修改application.yml配置文件

server:
  port: 20003

spring:
  application:
    name: config-server
  ## rabbitMQ用于Bus推送
  rabbitmq:
    host: 196.168.31.130
    port: 5672
    username: guest
    password: guest
  cloud:
    config:
      server:
        # 属性重载
        overrides:
          test: mytest
        git:
          uri: https://github.com/banxian-yao/foodie-cloud-config.git
          force-pull: true
          # 将配置文件放到接入方服务名称对应文件夹下面
          search-paths: '{application}'
          # username:
          # password:

eureka:
  client:
    serviceUrl:
      defaultZone: http://192.168.31.130:20000/eureka/
  #config-server默认是以hostname注册的，这边修改成ip地址注册
  instance:
    instance-id: ${spring.cloud.client.ip-address}.${server.port}
    prefer-ip-address: true

## 开启所有actuator-endpoint
management:
  endpoint:
    health:
      show-details: always
  endpoints:
    web:
      exposure:
        include: '*'
  security:
    enabled: false

2）修改Dockerfile
build会先从公网上下载需要的镜像，然后再build

FROM java:8
ADD config-server-1.0-SNAPSHOT.jar config-server-1.0-SNAPSHOT.jar
ENTRYPOINT ["java","-jar","config-server-1.0-SNAPSHOT.jar"]

3）通过Docfile创建镜像
build会先从公网上下载需要的镜像，然后再build

docker build -t  myconfig .

4）运行容器

docker run -d -p 20003:20003 --name myconfig myconfig 

5）查看注册中心
发现配置中心没有注册进来，重启eureka
