  1. eureka 启动该spring boot项目
  2. consul 启动consul可以使用docker启动，命令 docker run -p 8400:8400 -p 8500:8500 -p 8600:53/udp -h node1 -d progrium/consul -server -bootstrap -ui-dir /ui

配置信息参看api-gateway项目中配置文件

limiting模块实现降级、限流、滚动、灰度、AB、金丝雀等等等等 1 2

consul

目前consul service不支持metadata，使用tags进行设置，要想修改tags需要设置EnableTagOverride为true，目前spring cloud consul未提供EnableTagOverride的配置方式：

  • 1.使用如下命令将EnableTagOverride设置true
curl \
--request PUT \
--data '{
    "ID": "microservice-provider-user-docker-8081",
     "Name": "microservice-provider-user",
	  "Tags": [
	    "weight=55"
	  ],
	 "Address": "192.168.2.177",
	  "Port": 8081,
	  "EnableTagOverride": true

	}' \
http://localhost:8500/v1/agent/service/register
* 2.更行tags

       "Service": "microservice-provider-user",
       "Tags": [
           "weight=2"
       ],
       "EnableTagOverride": true, #可以覆盖tag
       "Address": "192.168.2.177",
       "Port": 8081
     },

执行命令：
    `curl \
          --request PUT \
          --data @payload.json \
