KubernetesClientException #337

Closed templary closed 2 years ago

templary commented 2 years ago

Hello, I would like to ask for info about this error.

After updating the system to shinyproxy 2.6.0 and containerproxy 0.8.10, a problem with launching applications in Kubernetes started to appear.

If I run the application locally on my machine and use the kubectl proxy and port-forward a given instance of the R application, the application runs without problems and everything works as it should.

The problem occurs when Shinyproxy is on a production version in a kubernetes cluster where this error occurs.

Thank you a lot for your time

Hi

Thanks for opening this issue. I never saw this issue starting to appear with the release of 2.6.0. Can you provide some additional information?

Thanks

Hello,

No, I don't use sidecar

For production version of ShinyProxy we are using G Cloud Kubernetes version 1.19.12

I happen on every app start. But just in production environment (when shinyproxy is also in Kubernetes). On my local dev version it works completely fine.

Hi

This seems like a strange issue. The Kubernetes client library should be able to auto discover the correct URL of the k8s API server. Are you sure you did not specify the proxy.kubernetes.url property? (maybe using an environment variable or something?) If this isn't the case you could maybe try specifying the proxy.kubernetes.url yourself. You could try setting it to https://kubernetes.default or https://kubernetes.default.svc.cluster.local. The exact domain my depend on your cluster configuration.

Hi thank you for your reply!

We solved problem just by adding this line to config file. Both of them make apps work.

url: https://kubernetes.default.svc.cluster.local 
url: https://kubernetes.default
