Kubernetes doesn't pull from private Docker Registry - docker

Question

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

kubectl describe pods private-image-test-1

Any help is welcome at this point, thanks!

In most cases where I've come across this issue, it is almost always your credential secret being incorrect. The proper format should be along the lines of
apiVersion: v1
kind: Secret
metadata:
name: registrypullsecret
data:
.dockerconfigjson: {BASE64 encoding of your config}
type: kubernetes.io/dockerconfigjson
From memory, the type field has changed in recent versions of k8s so definitely check that you have the correct type listed.
Also, your yaml example has bad indenting, but thats likely a SO editor issue.
