For initial installations, see the [Setup topics](https://kubernetes.io/docs/setup/pick-right-solution/) in the Kubernetes documentation.

- kubeadm now works better when not connected to the Internet. In addition,  common kubeadm commands will now work without an available networking interface. ([#67397](https://github.com/kubernetes/kubernetes/pull/67397), [@neolit123](https://github.com/neolit123))

- Kubeadm: now sets the host `OS` environment variables when executing `crictl` during image pulls. This fixed a bug where `*PROXY` environment variables did not affect `crictl` internet connectivity. ([#110134](https://github.com/kubernetes/kubernetes/pull/110134), [@mk46](https://github.com/mk46))

* Refactor factory_test.go to use a fake k8s client. ([#69412](https://github.com/kubernetes/kubernetes/pull/69412), [@tossmilestone](https://github.com/tossmilestone))
* kubeadm: fix a case where fetching a kubernetesVersion from the internet still happened even if some commands don't need it. ([#69645](https://github.com/kubernetes/kubernetes/pull/69645), [@neolit123](https://github.com/neolit123))

([#97621](https://github.com/kubernetes/kubernetes/pull/97621), [@vbannai](https://github.com/vbannai)) [SIG Cloud Provider]

* Add docs for [self-serving docs' (Swagger UI) static assets](https://fastapi.tiangolo.com/advanced/extending-openapi/#self-hosting-javascript-and-css-for-docs), e.g. to use the docs offline, or without Internet. Initial PR [#557](https://github.com/tiangolo/fastapi/pull/557) by [@svalouch](https://github.com/svalouch).
