We are creating a POC with CLIPPER. The deployment works fine with Docker in local environment, but we need to use kubernetes for the POC. We tried to deploy it in two ways:

1. Minikube deployment
2. GKE k8 cluster deployment

In both above cases: the mgmt-frontend, redis, and query-frontend images were all deployed successfully on the cluster:

We are getting an error when we are trying to start clipper:

Error connecting to Kubernetes cluster. No external node addresses found

    115             raise e
    116 

AttributeError: 'ClipperException' object has no attribute 'msg'

We tried different options but it didn't help. Can anyone please help us on this?
