It appears after having an API call to the kubernetes API, there is a log with the following message:
WARNING: A connection to https://10.96.0.1/ was leaked. Did you forget to close a response body? To see where this was allocated, set the OkHttpClient logger level to FINE: Logger.getLogger(OkHttpClient.class.getName()).setLevel(Level.FINE);
(10.96.0.1) is the kubernetes service in my local minikube.
Perhaps update to the latest kubernetes-client by fabric8?
