title: kubernetes, prompt freezes at port forward command
body: <p>I want to set up port forwarding from my local ports (nodes) to the pod redis-master after the online guide from <a href="https://kubernetes.io/docs/tasks/access-application-cluster/port-forward-access-application-cluster/" rel="noreferrer">kubernetes</a>.</p>
  
  <p>At the moment my prompt is frozen for more than 5 minutes at the <code>port-forward</code> command.</p>
  
  <pre><code>[root@k8s-master deployments]# kubectl create -f https://k8s.io/docs/tasks/access-application-cluster/redis-master.yaml
  pod "redis-master" created
  [root@k8s-master deployments]# kubectl get pods
  NAME                                READY     STATUS    RESTARTS   AGE
  redis-master                        2/2       Running   0          1m
  [root@k8s-master deployments]# kubectl get pods redis-master --template='{{(index (index .spec.containers 0).ports 0).containerPort}}{{"\n"}}'
  6379
  [root@k8s-master deployments]# kubectl port-forward redis-master 6379:6379
  Forwarding from 127.0.0.1:6379 -&gt; 6379
  ^C 
  </code></pre>
  
  <p>I don't know why my prompt is frozen. In my logs aren't some error or warn entries.</p>
