I've deployed a private registry and can pull from it with docker pull x.x.x/name. The thing is that I can't make Kubernetes pull from that repository. I think I've followed all the answers on other topics, but they don't seem to do the trick.

.yaml file:

apiVersion: v1
kind: Pod
metadata:
  name: private-image-test-1
spec:
  containers:
    - name: uses-private-image
      image: x.x.x/nginx_1
      imagePullPolicy: Always
      command: [ "echo", "SUCCESS" ]
  imagePullSecrets:
   - name: registrypullsecret

kubectl get pods:

NAME                   READY     STATUS                                                                 RESTARTS   AGE
private-image-test-1   0/1       Image: x.x.x/nginx_1 is ready, container is creating   0          4m

kubectl describe pods private-image-test-1

Any help is welcome at this point, thanks!
