Unable to connect to the server: net/http: TLS handshake timeout

Question

On minikube for windows I created a deployment on the kubernetes cluster, then I tried to scale it by changing replicas from 1 to 2, and after that kubectl hangs and my disk usage is 100%. I only have one container in my deployment

apiVersion: apps/v1
kind: Deployment
metadata:
  name: first-deployment
spec:
  replicas: 1
  selector:
    matchLabels:
      run: app
  template:
    metadata:
      labels:
        run: app
    spec:
      containers:
      - name: demo
        image: ner_app
        imagePullPolicy: IfNotPresent
        ports:
        - containerPort: 5000

all I did was run this after the pods were successfully deployed and running

kubectl scale --replicas=2 deployment first-deployment

In another terminal I was watching the pods using

kubectl get pods --watch

But everything is unresponsive and I'm not sure how to recover from this.

When I run kubectl get pods again it gives the following message

PS D:\docker\ner> kubectl get pods
Unable to connect to the server: net/http: TLS handshake timeout

Is there a way to recover, or cancel whatever process is running?

Also my VM's are on Hyper-V for Windows 10 Pro (minikube and Docker Desktop) both have the default RAM allocated - 2048MB

The container in my pod is a machine learning process and the model it loads could be large, in the order of 200MB to 300MB

Answer 1

You may have some proxy problems. Try following commands:

$ unset http_proxy
$ unset https_proxy

and repeat your kubectl call.

Answer 2

You can set up resource limits on deployments so that pods will not use the entire available resource in the node.
