footloose single-master example can't pull images #280

Open adensymonds opened 4 years ago

adensymonds commented 4 years ago

I am trying to follow the examples to get a simple single master cluster running using the docker backend and CentOS. I have successfully created the footloose machines. Then running wksctl apply appears to be successful, but monitoring the kubernetes cluster via kubectl, the cluster never comes up. It gets stuck trying to pull the images for weave-npc and wksctl-controller. The errors can be seen in the below kubectl excerpts. I would appreciate any guidance on being able to get this simple example running.

Output from kubectl get pods -A:
