Determining Platform Support Policies

[Jeremy Rickard]

Hello SIG Release, SIG Testing, and SIG K8s Infra!

We have had some ongoing discussions around the currently supported platforms and what we should do going forward. Some of this was driven by the recent issues we faces with s390x and ppc64le, but we also haven't revisited this in some time and we've had some additional questions about new platforms or build variants. We had a PR open to migrate over some existing documentation to the website, however it is dated and we figured we should revisit all of this and eventually produce a new KEP to define platform support. 

I have created a google doc[1] that contains the current state of the support, that I would like to invite everyone to review and comment on as we iterate to ultimately clearly define the "tiers" of support we provide and what artifacts we produce for those tiers. We will then work on a KEP to codify this. The document is currently just a snapshot of the existing tiers and the status of different artifacts. Please suggest requirements for tiers, with an eye toward testing requirements we should enforce and what infrastructure requirements should be present.  Other criteria, such as usage data, would also be interesting to consider.  

The doc is shared with testing, infra, and release mailing lists so please feel free to comment. 

Thanks!

Jeremy // on behalf of SIG Release

Did we reach a conclusion on this topic? I haven't seen any KEPs nor website PRs

documenting it.
