title: ImagePullBackOff error Google Kubernetes Engine
body: <p>I know a lot of people already had similar question, i read a few of them, but found nothing what actualy helped me so far.</p>
  
  <p>I have a gitlab with private repo enabled, I also use Google Kubernetes Engine. I have a few Docker container in my private repo, and I want to deploy one of them to the Kubernetes Engine.</p>
  
  <p>I have created a secret with <code>kubectl create secret generic db-user-pass --from-file=./username.txt --from-file=./password.txt</code>
  I also tried <code>kubectl create secret docker-registry name --docker-server=registry.xy.z --docker-username=google --docker-password=xyz --docker-email=xy@z.de</code>
  Then I created my Deployment file:</p>
  
  <pre><code>apiVersion: extensions/v1beta1
  kind: Deployment
  metadata:
  name: backend-test
  labels:
  app: 13371337
  spec:
  replicas: 1
  template:
  metadata:
  labels:
  app: 13371337
  spec:
    containers:
    - name: backend
      image: registry.xy.z/group/project/backend:latest
      imagePullPolicy: Always
      ports:
      - containerPort: 8080
    imagePullSecrets:
    - name: db-user-pass or name
  </code></pre>
  
  <p>Any ideas how to get it running?</p>
