HTTP 客户端（声明式或低级）无法从 pod [Micronaut 1.1.4] 访问互联网

Question

我构建了一个简单的 micronaut 项目，它像 tutorial 中显示的那样获取 Bintray。

当我这样访问容器时：

kubectl exec -it -n namespace demo sh

然后我可以执行一个 curl 看起来像这样

curl -x proxy:port https://bintray.com/path

这是工作。不幸的是，我的应用程序中的客户端调用相同的 url 无法成功。

MyController.java

...
@Client("https://bintray.com/path/")
@Inject
RxHttpClient myclient;
...

申请-k8s.yml

micronaut:
  http:
    client:
      proxy-address: proxy:port
      proxy-type: HTTP

虽然运行在我的本地机器上测试和测试一切正常。

但是在 Kubernetes 上我有错误：

io.micronaut.http.server.netty.RoutingInBoundHandler
io.micronaut.http.server.netty.RoutingInBoundHandler: 
Unexpected error occurred: Connect Error: bintray.com : System error

我的问题是要知道使 micronaut 在 kubernetes 上工作的正确配置是什么？

是否有任何关于如何为 K8s 配置 Micronaut 的教程或扩展文档？

Answer 1

使用 Micronaut 1.2 似乎一切正常。

HTTP 客户端（声明式或低级）无法从 pod [Micronaut 1.1.4] 访问互联网

HTTP Client (Declarative or Low Level) could not access internet from the pod [Micronaut 1.1.4]
