“Safely Drain a Node” states that you need Kubernetes 1.5 or later

[wsmelton]

The PR #23755 improperly set the minim version to 1.5 when there is no such version.

kubernetes 1.5 release end of life (1 October 2017) already passed so this page needs updation

I guess it is mentioned because in v1.5:

[beta] PodDisruptionBudget has been promoted to beta, can be used to safely drain nodes while respecting application SLO's (docs) (kubernetes/enhancements#85)

As per release page

The Kubernetes project maintains release branches for the most recent three minor releases (1.26, 1.25, 1.24). Kubernetes 1.19 and newer receive approximately 1 year of patch support. Kubernetes 1.18 and older received approximately 9 months of patch support.

It totally depends upon the docs and
/sig node
what they want to mention. If it is mentioned because of the time this feature went beta this page might be right.

That statement is correct and its inclusion does not, to me, feel misleading.

Just to confirm the version indicates the complete functionality is not available until v1.5 is released?

PDB is noted released in stable 1.21. Only confusing area is what functionality in the document is for 1.5 and what is available now?

The page does not say you need to wait for an upcoming release. I think you have misunderstood what is actually a clear statement @wsmelton.

We could drop the version-check shortcode as we assume everyone is using Kubernetes 1.21 or later.

Drop the version-check would be desireable.

For SIG Docs, this is only a backlog priority I think. We've other work that we'd want to prioritize.

Help here is still very welcome!
