Follow up from #11060, tracked in #12329

what is our stated support or testing for transitive or third-party dependencies?

I see three main categories of dependencies and sets of questions that are unanswered in current documentation:

  • etcd
    • what versions are tested? what is the minimum and maximum supported version? should this info be in a machine-consumable format?
    • is there a tested or recommended upgrade order/process?
  • dependencies (things the kubelet/apiserver/controllers interact with via CRI, CNI, CSI, KMS APIs)
    • what API versions are tested/supported
    • what specific implementations/versions are tested?
    • is there a tested or recommended upgrade order/process?
    • when we say we recommend container engine or CSI driver A at version B for k8s release 1.n, does that imply we expect k8s release 1.n+2 to support the same to cover maximum skew?
  • addons that are bundled with kubernetes releases
    • what versions of these dependencies are tested and bundled in kubernetes release 1.X? should this info be in a machine-consumable format?
    • if there a tested or recommended upgrade order/process (e.g. if the add-on is defined in a daemonset, should the new daemonset be applied before/after upgrading the control plane, before/after upgrading the kubelets)?

Finally, where should this information be maintained (a unified page with a version matrix, per-release, or something else)?

(#12233 is open specifically for etcd)

sig-cluster-lifecycle, sig-testing: hello, we need feedback and approval for the proposals in this ticket from chairs with respect to LTS.

Some initial thoughts:

etcd

I think of etcd as largely an implementation detail of the apiserver and owned by sig-apimachinery. I know that other folks in sig cluster lifecycle (e.g. @justinsb) have a different opinion, but I would love to see folks from apimachinery who work more closely with etcd (such as @jpbetz) help define the supported versions per release and the upgrade process.

My understanding is that right now we basically test a single version of etcd3 for each release (at least for the vast majority of tests) although we still claim support for etcd2 as well.

Dependencies

These are generally integrated / tested / qualified by the SIG that owns the interface, e.g. sig node would qualify various CRIs for a release or sig storage would qualify the CSI driver for a release. From what I've seen historically, as with etcd it's often been a single implementation that gets the vast majority of the test cycles and then an alternate version may be run through some tests to ensure compatibility.

Addons

Right now "addons" are implicitly bundled with the release in the form of container version references in yaml files in the cluster directory of the release tarball. I'm not sure who, other than kube-up, actually relies on this, but as we would like to get rid of the cluster directory hopefully the list of consumers of those yaml files is small.

@justinsb and @johnsonj have proposed a new way for managing addons, and along with that we will need to come up with a way to track addons per k8s release. One suggestion has been to use the bundle (https://github.com/GoogleCloudPlatform/k8s-cluster-bundle) as a schematic way to represent a set of components that have been tested and qualified together.
