Update /docs/setup/independent/create-cluster-kubeadm.md for 1.8. #5524

mattmoyer · 2017-09-18T18:45:35Z

This introduction needed a couple of small tweaks to cover the --discovery-token-ca-cert-hash flag added in kubernetes/kubernetes#49520.

This change is

luxas

Some other things have to be addressed. Thanks!

Specifically, kubeadm relies on some features (bootstrap tokens, cluster signing), that are still considered alpha

Not true anymore

The implementation may change as the tool evolves to support even easier upgrades and high availability (HA)

May change slightly with HA. We now promise backwards compat. Upgrades are now supported

Paste new output from init/join

Link to both v1.6->v1.7 and v1.7->v1.8 upgrading doc. The latter can also be used for v1.7.x -> v1.7.y upgrades

We said alpha in #5497 (comment).

Oh, I was confused by this because I thought you meant self-hosting. We agreed that self-hosting is alpha but the overall implementation of kubeadm is now beta? I'll update that.

What about the config file format? Also now beta?

@mattmoyer, Please rebase your branch so that it picks up 99fbc2b. That will fix the deploy/netlify failure. Thanks.

1.6-1.7 is this

I wonder if we should just drop this doc for 1.8? I'm not sure exactly how our version deprecation policy applies in this case, but it seems like 1.8 docs shouldn't need to cover anything about 1.6.

@luxas and I talked in Slack and he'd like to keep this around until 1.9 (which is fine with me).

@steveperry-53 apologies, I've been afk most of this week and didn't get to update this until just now.

PTAL, I think I've addressed everything for now.

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.
