[GitHub] [dubbo-go-samples] whitekeyboard opened a new issue #6: kubernetes是否可以基于最新的DUBBO版本提供镜像 

whitekeyboard opened a new issue #6:
URL: https://github.com/apache/dubbo-go-samples/issues/6


   https://github.com/apache/dubbo-go-samples/tree/master/registry/kubernetes
   此例子是基于dubbo-v1.3.0的版本，且为2020年3月16日的版本，当前dubbogo中已经提交了很次代码，建议基于最新dubbo-go提供一个新的镜像范例。当前的例子应该不兼容最新的dubbo-go了，比如DUBBO_NAMESPACE环境变量的注入。
   
   谢谢！

   I create a [repository](https://github.com/dubbo-x/k8s-registry) for k8s registry, and master branch denotes the latest (latest denotes v3.0.0-rc2 temporarily). @whitekeyboard @kms9 
   
   @kms9 To solve your error, add a [dubbo namespace environment](https://github.com/dubbo-x/k8s-registry/blob/99337598714b553f655887ef9459995678935200/yaml/client.yaml#L10-L12) in client.yaml. This environment variable ([[1](https://github.com/apache/dubbo-go/blob/cee963fd392eeb8f2daa445f9bfda1b8ee6e67dd/remoting/kubernetes/registry_controller.go)], [[2](https://github.com/apache/dubbo-go/blob/cee963fd392eeb8f2daa445f9bfda1b8ee6e67dd/remoting/kubernetes/registry_controller.go)]) seems to be used for client to watch the namespace where server reside.

   @gaoxinge  实验了一下 代码确实可以的. 不过 貌似不支持夸namespace? 不知道是不是我配置的问题.

   @gaoxinge  给到的示例 使用的是  dubbo-go v3里面默认的配置 运行确实没有问题 但是 自己替换 user的暴露的方法时候  遇到了 注册到 k8s `dubbo.io/annotation` 的 还是 `/dubbo/com.ikurento.user.UserProvider/providers` 不会根据配置文件改变.

   @kms9 是把下面两个文件关于user的暴露的方法都改了，但是pod的annotation的key `dubbo.io/annotation`对应的value还是没有变？

   @kms9 你的意思是：虽然改了代码和配置，但是感觉新代码没有生效，pod里面还是跑的老代码？
   
   直接拿你的代码跑了一下，也单独建了一个[分支](https://github.com/dubbo-x/k8s-registry/tree/dubbo-go-samples-issue6-0)（改了一些路径和镜像名，其他保持一致）跑了一下，新代码应该没有问题（client pod能打印出结果）：
   
   ![929A8D05-06C5-4c76-98E3-2B6457EE12F0](https://user-images.githubusercontent.com/16648345/124342766-f1cc4300-dbf8-11eb-85dd-bc3d14b55f31.png)
   
   我猜测可能是：client.sh/server.sh中打完镜像，上传镜像，然后k8s去拉镜像（client-k8s.yaml/server-k8s.yaml里面是`imagePullPolicy: Always`，每次都会拉镜像，写的很细节）的时候，会不会远程hub缓存了老的镜像，导致拉取下来的任然是老的镜像。
   
   你要不每次打镜像的时候，都更新一下tag（现在一直是v1.1），然后多试几次看看。
