title: Kubernetes pod not starting
body: <p>I have a kubernetes cluster with 5 nodes. When I add a simple nginx pod it will be scheduled to one of the nodes but it will not start up. It will not even pull the image.</p>
  
  <p>This is the nginx.yaml file:</p>
  
  <pre><code>apiVersion: v1
  kind: Pod 
  metadata:
    name: nginx
  spec:
    containers:
    - name: nginx
      image: nginx
      ports:
      - containerPort: 80
  </code></pre>
  
  <p>when I describe the pod there is one event: <code>Successfully assigned busybox to up02</code> When I log in to the up02 and check to see if there are any images pulled I see it didn't get pulled so I pulled it manually (I thought maybe it needs some kick start ;) )</p>
  
  <p>The pod will allways stay in the Container creating state. It's not only with this pod, the problem is with any pod I try to add.</p>
  
  <p>There are some pods running on the machine which is necessary for Kubernetes to operate:</p>
