docker swarm 集成 Spring Cloud 验证

开始

* 机器选择 Centos 7 4Gb内存 * systemctl stop firewalld * systemctl disable firewalld * yum install -y docker-io * yum install -y vim * systemctl start docker * systemctl enable docker

docker swarm init

* 任意一台机器执行 `docker swarm init ` * 讲得到的 结果 `copy` * 在其他两台机器上执行 * 配置 docker swarm 的启动文件

注意启动顺序

#可以拆开分开执行
docker stack deploy -c  emeos.yml demo
    

问题解析

* 其中spring-cloud

spring:
  cloud:
    config:
      profile: ${config.profile:dev}
      discovery:
        enabled: true
        service-id: ${APPLICATION_CONFIG_NAME}
  application:
      name: ${APPLICATION_NAME}
security:
  basic:
    enabled: false
  user:
    name: emos #eureka 用户名
    password: emos #eureka 密码
eureka:
  client:
    serviceUrl:
      defaultZone: ${EUREKA_SERVER_ADDRESS}
  instance:
    status-page-url-path: /swagger-ui.html
    hostname: ${HOST_NAME}
management:
  security:
    enabled: false

    

* `HOST_NAME` 是要用 `swarm` 启动的服务名来定义的例如：`ths-account` * `EUREKA_SERVER_ADDRESS` 是高可用服务 * `APPLICATION_NAME` 是当前的 `APPLICATION`的名字需要进行配置 * `APPLICATION_CONFIG_NAME` 是`config`服务的`application`名称 有些服务需要配置此项 * `以上可能不善于表达，仅仅是技术方向的实现验证时间：2018年4月23日`
