statically to `IfNotPresent` for all required images. If you want to always pull the latest images before cluster init (as `Always` would do), run `kubeadm config images pull` before each `kubeadm init`. If you don't want the kubelet to pull any images at `kubeadm init` time, for example if you don't have an internet connection, you can also run `kubeadm config images pull` before `kubeadm init` or side-load the images some other way (such as `docker load -i image.tar`). Having the images locally cached...

- Joining control plane nodes to a HA cluster can now be simplified by enabling the optional automatic copy of certificates from an existing control plane node.
- You can now use `kubeadm init --experimental-upload-certs` and `kubeadm join --experimental-control-plane --certificate-key`.
kubernetes/kubeadm: [#1373](https://github.com/kubernetes/kubeadm/issues/1373)

#### **Federation**

*   Kubefed init now supports --imagePullSecrets and --imagePullPolicy, making it possible to use private registries. ([#50740](https://github.com/kubernetes/kubernetes/pull/50740),[ @dixudx](https://github.com/dixudx))
*   Updated cluster printer to enable --show-labels ([#53771](https://github.com/kubernetes/kubernetes/pull/53771),[ @dixudx](https://github.com/dixudx))

## Changes since v1.3.0-beta.1
