I'm trying to setup GCR with kubernetes

and getting Error: ErrImagePull Failed to pull image "eu.gcr.io/xxx/nodejs": rpc error: code = Unknown desc = Error response from daemon: pull access denied for eu.gcr.io/xxx/nodejs, repository does not exist or may require 'docker login'

Although I have setup the secret correctly in the service account, and added image pull secrets in the deployment spec

deployment.yml

apiVersion: extensions/v1beta1
kind: Deployment

    kompose.cmd: kompose convert

          valueFrom:
            secretKeyRef:
              name: mongo-secret
              key: MONGO_USERNAME
        image: "eu.gcr.io/xxx/nodejs"
        name: nodejs
        imagePullPolicy: Always
        ports:
        - containerPort: 8080
        resources: {}
      imagePullSecrets:
        - name: gcr-json-key
      initContainers:
        - name: init-db
          image: busybox
          command: ['sh', '-c', 'until nc -z db:27017; do echo waiting for db; sleep 2; done;']
      restartPolicy: Always
status: {}

used this to add the secret, and it said created

kubectl create secret docker-registry gcr-json-key --docker-server=eu.gcr.io  --docker-username=_json_key  --docker-password="$(cat mycreds.json)"   --docker-email=mygcpemail@gmail.com

How can I debug this, any ideas are welcome!
