Extract and Import the Docker images locally to the master1 node.

$ mkdir /tmp/import
$ for f in images/*.gz; do IMG=$(basename "${f}" .gz); gunzip -c "${f}" > /tmp/import/"${IMG}"; done
$ for f in /tmp/import/*.tar; do ctr -n=k8s.io images import "${f}"; done

$ helm upgrade --install  gv-private-registry charts/gv-private-registry-$VERSION.tgz --wait \
  --timeout=10m0s \
  --kubeconfig /etc/rancher/k3s/k3s.yaml
```
