title: What does Kubernetes Pods `ErrImagePull` means?
body: <p>I am at the initial stage of Kubernetes. I've just created a pod using the command:</p>
  <pre><code>kubectl apply -f posts.yaml
  </code></pre>
  <p>It returns me the following:</p>
  <pre><code>pod/posts created
  </code></pre>
  <p>After that when I run <code>kubectl get pods</code></p>
  <p>I found the result as following:</p>
  <pre><code>NAME    READY   STATUS         RESTARTS   AGE
  posts   0/1     ErrImagePull   0          2m4s
  </code></pre>
  <p>Here is my <code>posts.yaml</code> file in below:</p>
  <pre><code>apiVersion: v1
  kind: Pod
  metadata:
      name: posts
  spec:
      containers:
          - name: posts
            image: bappa/posts:0.0.1
  </code></pre>
