Error response from daemon: Get https://armdocker.rnd.se/v1/_ping: Not Found - kubernetes

Question

I am using Kubernetes version 1.10.
I am trying to pull an image from a local docker repo. I already have the correct secret created.
[root#node1 ~]# kubectl get secret
NAME TYPE DATA AGE
arm-docker kubernetes.io/dockerconfigjson 1 10m
Checking the secret in detail gives me the correct auth token
[root#node1 ~]# kubectl get secret arm-docker --output="jsonpath={.data.\.dockerconfigjson}" | base64 -d
{"auths":{"armdocker.rnd.se":{"username":"<MY-USERNAME>","password":"<MY-PASSWORD>","email":"<MY-EMAIL>","auth":"<CORRECT_AUTH_TOKEN>"}}}
But when I create a Pod, Im getting the following ERROR :
Events:

Warning Failed 1s (x2 over 12s) kubelet, node6 Error: ErrImagePull
Why is it looking for /v1/_ping ? Can I disable this somehow ?
Im unable to understand what is the problem here.

Once defined your secret, you need to use it inside your pod (you didn't whether you used it).
kind: Pod
...
spec:
imagePullSecrets:
- name: arm-docker
