wouldn't kubectl be brought in by deps ?

Yes, but this makes it explicit to the user

@kad Good idea. Done.

I tested this on Debian 9 and it works flawlessly as well. The only earlier blocker was that 7 and 8 didn't enable the memory cgroup, and we didn't want to tell the user to reboot & mock with their kernel cmdline to install k8s. Now that's not needed anymore 🎉

Would it be appropriate to link to the tracking issue here, for those who are interested? I'm not sure how often we do that from our user docs.

I don't think right now is necessary. We haven't specced out a plan yet

LGTM (without actually having tested the instructions). I just left a few minor comments.

(#5678) - The kubelet upgrade instructions should be done on every host, not just worker nodes. - We should just upgrade all packages, instead of calling out kubelet specifically. This will also upgrade kubectl, kubeadm, and kubernetes-cni, if installed. - Draining nodes should also ignore daemonsets, and master errors can be ignored. - Make sure that the new kubeadm download is chmoded correctly. - Add a step to run `kubeadm version` to verify after downloading. - Manually approve new kubelet CSRs if rotation is enabled (known issue). * Release 1.8 (#5680) * Fix versions for 1.8 API ref docs * Updates for 1.8 kubectl reference docs * Kubeadm /docs/admin/kubeadm.md cleanup, editing. (#5681) * Update docs/admin/kubeadm.md (mostly 1.8 related). This is Fabrizio's work, which I'm committing along with my edits (in a commit on top of this). * A few of my own edits to clarify and clean up some Markdown.
