Kubeadm: HA documentation update

[chuckha]

The Configure SSH section in this document has caused much confusion. I would love some help finding an easier way to approach this.

I think outlining why we are configuring SSH would be a good starting point, but maybe ssh-agent is not well known enough and we should stick to very basic, albeit verbose, commands.

Uhhmm
I don't think we should outline a solution for doing SSH because there is already plenty of public doc for this (eventually we should link something instead)

[neolit123]

i agree with @fabriziopandini
e.g. link to http://rabexc.org/posts/using-ssh-agent

Personally I would love to know why SSH is required. As a user, when I understanding reason for each step I can plan alternative solutions \ workarounds as needed.

[neolit123]

expending with a sentence on two on why ssh is needed here and what it does might help users.

[chuckha]

Yeah, explain why ssh is needed then suggest "here is one way to do it ssh-agent instructions".

From #706

We need to go through an update to the docs using the control-plane-join

Even if I'm looking forward for getting user feedbacks for the control-plane-join I have some doubts about this, because it was decided to not document alpha features on the public web site.

kubernetes/website#10264 is merged, closing.
