I am running Kubernetes on CentOS 7, and I am unable to deploy pods.  After running

# kubectl run nginx --image=nginx

I run

# kubectl describe pod nginx

which gives the following output:

If you scroll the last line, you’ll see that it’s going to redhat.com and failing.  I don’t know why it’s going to the RedHat repo for image pull; it should pull from docker hub.

not recommand edit /etc/kubernetes/kubelet to solve this error. if you see image pull failed for registry.access.redhat.com/rhel7/pod-infrastructure:latest, you can try run command:

yum install -y rhsm

I solved the same error after run the command.

  • is it a redhat repository? – Mohd Nov 30 '17 at 6:31
  • This doesn't work when you're using centos. I had to run "yum install subscription-manager". That appeared to work. – Matthew Jan 17 at 14:54

I solved it commenting the line :

KUBELET_POD_INFRA_CONTAINER="--pod-infra-containerimage=registry.access.redhat.com/rhel7/pod-infrastructure:latest"

in /etc/kubernetes/kubelet

on each of my slaves
