the user does not provide details about the exact problem.

this page already provides info on how to download Docker images if no i-net connection is available:
https://kubernetes.io/docs/reference/setup-tools/kubeadm/kubeadm-init/
Running kubeadm without an internet connection

Google also returns the above page as a first result for:
kubeadm without internet.

suggesting /close.

Here's the header to the docs for this:
https://kubernetes.io/docs/reference/setup-tools/kubeadm/kubeadm-init#running-kubeadm-without-an-internet-connection

It's rather minimal in describing what "pre-pulling images" means, but that's out of scope as it's runtime specific.

Closing as suggested.

[timothysc]

The list images PR also helps, and we should update that doc.

@timothysc are you referring to @chuckha's PR?

[chuckha]

there was a list-images pr already merged, then it got move to images list and the PR you linked to is for an images pull command.

list-images: https://github.com/kubernetes/kubernetes/pull/63450
refactor to images list: https://github.com/kubernetes/kubernetes/pull/63811
