imageRepository option not taken into account for the pause image

[sebastien-prudhomme]

BUG REPORT

Versions

kubeadm version (use kubeadm version): 1.8.3

Environment:

• Kubernetes version (use kubectl version): 1.8.3
• Cloud provider or hardware configuration:
• OS (e.g. from /etc/os-release): CentOS 7.4
• Kernel (e.g. uname -a): 3.10.0-693.5.2.el7.x86_64
• Others:

What happened?

When using a config file with imageRepository set to other value than gcr.io/google_containers, the image pulled for the "pause" container is still gcr.io/google_containers/pause-amd64:3.0

All other image are correctly pulled from the right registry.

What you expected to happen?

The image for the "pause" container should be pulled from the custom registry.

[roadmapper]

This is not really a kubeadm bug; the kubelet is installed independently from kubeadm and thus has its own configuration for the pause container. See #257 (comment) for a way to specify the pause image location.
