keywords: swarm

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-clou
  

  
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
