When deploying in Airgap environments (using tarball installation), there is a tarball for the system-upgrade-controller image. However, we also need to include the kubectl image but the required version is not that obvious. We need to inspect the yaml file that install system-upgrade-controller and check the kubectl image version.
If both images were part of the image tarball, the automatic upgrade in airgap scenarios would be easier to prepare.
Describe the solution you'd like
A clear and concise description of what you want to happen.
Adding a tarball "bundle-kubectl-suc.tar.gz" in /var/lib/rancher/${distro}/agent/images/ will upload both images in the containerd image registry
Describe alternatives you've considered
A clear and concise description of any alternative solutions or features you've considered.
1 - Look at the suc manifest and check what kubectl version is needed
2 - Docker save that kubectl image
3 - scp that image to the airgap node
4 - Place that image in /var/lib/rancher/${distro}/agent/images/
By doing this, we would save 3 steps
