Proposal for Node Lifecycle WG with SIG Arch

[Jonathan Innis]

Hey everyone 👋

Shared this to the SIG Arch mailing list, but if you are not on that mailing list, here's the context:

Up to this point, Autoscaling and Karpenter have been collaborating together in Working Group discussions around Karpenter’s proposal to join the SIG (see https://github.com/kubernetes/org/issues/4258). Part of that discussion has involved thinking around how parts of Cluster Autoscaler’s (CAS) behaviors and APIs have parallels in Karpenter, prompting a discussion around API alignment between the two projects, leading to an AEP proposal around alignment.

One of our thoughts around this was that CAS and Karpenter could align their APIs into a broader namespace that deals with node lifecycle behaviors in general e.g. node-lifecycle.kubernetes.io , though we recognize that this has broader scope than what SIG Autoscaling can handle alone. In particular, we think we can make some progress in resolving some of the gaps outlined here: https://github.com/kubernetes/kubernetes/issues/115139.

We’re planning to attend the SIG Arch Working Group session on Oct. 5 to start some discussion around this, with the intent to propose a working group session across SIGs that would want to be involved here e.g. SIG Arch, SIG Autoscaling, SIG Node, SIG Cluster Lifecycle, etc. 

Please join the meeting if you are interested in adding input to this discussion.

Meeting Time: 60 minutes in length, every other Thursday at 11:00 PT / 2:00 ET / 19:00 UTC
