Question

我建立了一个简单的micronaut项目，该项目像本tutorial中的展示一样获取Bintray。

当我这样访问容器时：

kubectl exec -it -n namespace demo sh

然后我可以像这样执行卷曲

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

而且有效。不幸的是，我的应用程序内调用相同URL的客户端无法成功。

MyController.java

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

application-k8s.yml

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

在本地计算机上运行测试和测试时，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

我的问题是要知道什么是使micronaut在kubernetes上正常工作的正确配置？

是否有关于如何为K8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（声明性或低级）无法从Pod [Micronaut 1.1.4]访问互联网
