|
|
## 一、部署结构
|
|
|
|
|
|
<img src="./imgs/structs.png"/>
|
|
|
|
|
|
如上图所示，一共有三个环境：
|
|
|
1. 基线环境，包含 FrontService、MiddleService、BackendService
|
|
|
2. feature1 环境，包含 MiddleService、BackendService
|
|
|
3. feature2 环境，包含 FrontService、BackendService
|
|
|
|
|
|
并且在入口处，部署网关服务。
|
|
|
|
|
|
三条请求链路：
|
|
|
1. 基线环境链路，Gateway -> FrontService(基线) -> MiddleService(基线) -> BackendService(基线)
|
|
|
2. feature1 环境链路，Gateway -> FrontService(基线) -> MiddleService(feature1) -> BackendService(feature1)
|
|
|
3. feature2 环境链路，Gateway -> FrontService(feature2) -> MiddleService(基线) -> BackendService(feature2)
|
|
|
|
|
|
|
|
|
## 二、运行样例
|
|
|
|
|
|
无需任何代码变更，直接启动 base、feature1、feature2、featureenv-gateway 下所有应用即可。
|
|
|
|
|
|
应用默认指向北极星官方的体验环境，启动成功后可直接到体验站点查看服务注册数据。

## 三、测试
|
|
|
|
|
|
### 方式一：客户端打标
|
|
|
|
|
|
#### 基线环境链路
|
|
|
````
|
|
|
curl http://127.0.0.1:9999/featureenv-front-example/router/rest
|
|
|
````
|
|
|
响应结果（base 表示基线环境）
|
|
|
````
|
|
|
featureenv-front-example[base] -> featureenv-middle-example[base] -> featureenv-backend-example[base]
|
|
|
````
|
|
|
|
|
|
#### feature1 环境链路
|
|
|
|
|
|
通过 X-Polaris-Metadata-Transitive-featureenv 请求头指定特性环境。
|
|
|
|
|
|
````
|
|
|
curl -H'X-Polaris-Metadata-Transitive-featureenv:feature1' http://127.0.0.1:9999/featureenv-front-example/router/rest
|
|
|
````
|
|
|
响应结果
|
|
|
````
|
|
|
featureenv-front-example[base] -> featureenv-middle-example[feature1] -> featureenv-backend-example[feature1]
|
|
|
````
|
|
|
|
|
|
#### feature2 环境链路
|
|
|
|
|
|
通过 X-Polaris-Metadata-Transitive-featureenv 请求头指定特性环境。
|
|
|
|
|
|
````
|
|
|
curl -H'X-Polaris-Metadata-Transitive-featureenv:feature2' http://127.0.0.1:9999/featureenv-front-example/router/rest
|
|
|
````
|
|
|
响应结果
|
|
|
````
|
|
|
featureenv-front-example[feature2] -> featureenv-middle-example[base] -> featureenv-backend-example[feature2]
|
|
|
````
|
|
|
|
|
|
### 方式二：网关流量染色
|
|
|
|
|
|
模拟一种实际的场景，假设客户端请求有一个 uid 请求参数，期望:
|
|
|
1. uid=1000 的请求打到 feature1 环境
|
|
|
2. uid=2000 的请求打到 feature2 环境
|
|
|
3. 其它 uid 的请求打到基线环境
|
|
|
|
|
|
**配置染色规则**
|
|
|
|
|
|
配置地址：http://14.116.241.63:8080/#/filegroup-detail?group=featureenv-gateway&namespace=default
|
|
|
|
|
|
修改 rule/staining.json 配置文件，填写以下规则:
|
|
|
|
|
|
````json
|
|
|
{
|
|
|
"rules":[
|
|
|
{
|
|
|
"conditions":[
|
|
|
{
|
|
|
"key":"${http.query.uid}",
|
|
|
"values":["1000"],
|
|
|
"operation":"EQUAL"
|
|
|
}
|
|
|
],
|
|
|
"labels":[
|
|
|
{
|
|
|
"key":"featureenv",
|
|
|
"value":"feature1"
|
|
|
}
|
|
|
]
|
|
|
},
|
|
|
{
|
|
|
"conditions":[
|
|
|
{
|
|
|
"key":"${http.query.uid}",
|
|
|
"values":["2000"],
|
|
|
"operation":"EQUAL"
|
|
|
}
|
|
|
],
|
|
|
"labels":[
|
|
|
{
|
|
|
"key":"featureenv",
|
|
|
"value":"feature2"
|
|
|
}
|
|
|
]
|
|
|
}
|
|
|
]
|
|
|
}
|
|
|
````
|
|
|
|
|
|
填写完后发布配置即可。
