Are you planning to introduce support for Low-Priority VMs on VMSS?
In my opinion it would enable really interesting scenarios

[feiskyer]

@danigian Yep, I think so. Let me check this after v1.10 release.

@feiskyer

@feiskyer please fill out the appropriate line item of the
1.11 feature tracking spreadsheet
and open a placeholder docs PR against the
release-1.11 branch
by 5/25/2018 (tomorrow as I write this) if new docs or docs changes are
needed and a relevant PR has not yet been opened.

[justaugustus]

@feiskyer -- We're doing one more sweep of the 1.11 Features tracking spreadsheet.
Would you mind filling in any incomplete / blank fields for this feature's line item?

Hey there! @feiskyer I'm the wrangler for the Docs this release. Is there any chance I could have you open up a docs PR against the release-1.12 branch as a placeholder? That gives us more confidence in the feature shipping in this release and gives me something to work with when we start doing reviews/edits. Thanks! If this feature does not require docs, could you please update the features tracking spreadsheet to reflect it?

[justaugustus]

@feiskyer --
Any update on docs status for this feature? Are we still planning to land it for 1.12?
At this point, code freeze is upon us, and docs are due on 9/7 (2 days).
If we don't here anything back regarding this feature ASAP, we'll need to remove it from the milestone.

[feiskyer]

@justaugustus Yep, still tracked for v1.12. No docs are needed.

[justaugustus]

Thanks for the update!

[djsly]

@feiskyer would you have a list of items still needed to VMSS with k8s ?

[feiskyer]

@djsly No, I think the feature has been finished and could be closed after v1.12 release. Do you have additional ideas on this?

[djsly]

I'm about to spin up Staging clusters with 1.11.3 so I will know more in the coming weeks :)
Right now, most of my concerns are with VM Extension error handling with cluster autoscaler. But that's out of scope for here, we can take it offline :)

[feiskyer]

@djsly Could you open an issue for it on autoscaler repo?

[feiskyer]

GA and done now. Let's close it.

[k8s-ci-robot]
