title: kubernetes pdb ALLOWED DISRUPTIONS is 0
body: <p>I am trying to deploy a <a href="https://kubernetes.io/docs/tasks/run-application/configure-pdb/" rel="nofollow noreferrer">PodDisruptionBudget</a> for my deployment, but when I deploy this example</p>
  <pre><code>apiVersion: policy/v1
  kind: PodDisruptionBudget
  metadata:
    name: example-pdb
  spec:
    minAvailable: 1
    selector:
      matchLabels:
        app: example-deployment
  </code></pre>
  <p>with this deployment</p>
  <pre><code>apiVersion: apps/v1
  kind: Deployment
  metadata:
    name: example-deployment
  spec:
    replicas: 1
    selector:
      matchLabels:
        app: example-deployment-app
    template:
      metadata:
        labels:
          app: example-deployment-app
      spec:
          ...
  </code></pre>
  <p>I get the response</p>
  <pre><code>$ kubectl get pdb
  NAME          MIN AVAILABLE   MAX UNAVAILABLE   ALLOWED DISRUPTIONS   AGE
  example-pdb   1               N/A               0                     7s
  </code></pre>
  <p>What does it mean for &quot;ALLOWED DISRUPTIONS&quot; to be 0?</p>
