pull access denied repository does not exist or may require docker login

Please note that the error message from Docker is misleading.

$ docker build deploy/.
Sending build context to Docker daemon  5.632kB
Step 1/16 : FROM rhel7:latest
pull access denied for rhel7, repository does not exist or may require 'docker login'

It says that it may require 'docker login'. I struggled with this. I realized the image does not exist at https://hub.docker.com any more. I hope this helps someone.

Just make sure to write the docker name correctly!

In my case, I wrote (notice the extra 'u'):

FROM ubunutu:16.04

The correct docker name is:

FROM ubuntu:16.04

I had the same issue. In my case it was a private registry. So I had to create a secret as shown here

and then we have to add the image pull secret to the deployment.yaml file as shown below.

pods/private-reg-pod.yaml  
apiVersion: v1
kind: Pod
metadata:
  name: private-reg
spec:
  containers:
  - name: private-reg-container
    image: <your-private-image>
  imagePullSecrets:
  - name: regcred
