First draft of SIG Cluster Lifecycle related relnotes. #391

pipejakob · 2017-08-14T22:36:59Z

These are mostly populated from the issues labeled for sig/cluster-lifecycle and 1.8. I have reworded them in places to change from future to past tense and have more consistent verbiage.

CC @timothysc @luxas @justinsb @jbeda @mkumatag @ixdy @wlan0 @aaronlevy @diegs

Could everyone on the above CC list please take a look at the feature(s) you own and sign off on their representation here?

Also, if there is anything that is definitely going to slip the 1.8 release, now is a good time to pull it out of the release notes and update its issue.

@yujuhong I will place a WIP and updated proposal with details by the end of this week.

Cool. Are the release notes accurate so far? At least for a first draft?

@sjenning this is sig-cluster-lifecycles proposed additions, not sig-node.

@timothysc oh I see, sorry. Just found out about this hidden process since the release-note tags in feature PRs are apparently not used for anything now.

+* [beta] Kubernetes now has automated continuous-integration tests against all of our supported platforms (amd64, armhfp, aarch64, ppc64le, s390x), to ensure that it continues to work on these platforms. It's also possible to run clusters with nodes of mixed architectures.

+#### kubeadm
+* [beta] A new `phase` subcommand supports performing only subtasks of the full `kubeadm init` flow. Combined with fine-grained configuration, kubeadm is now more easily consumable by higher-level provisioning tools like kops or GKE.

Should be [beta]. Not sure whether self-hosted will be true or not, but I'm fine with leaving that as-is, as I think we're gonna meet the deadline for self-hosting upgrades as well (add-first-then-kill)

pipejakob · 2017-08-16T17:03:39Z

I've updated a few things based on feedback in a new commit so it's easy to see what changed. I'll squash into one commit before merging (after an LGTM).

It's also possible to run clusters with nodes of mixed architectures.

Not really sure whether we can say we have automated CI tests. All we have is conformance tests running on platforms ( amd64, armhfp, aarch64, ppc64le). @luxas WDYT?

Note - remove s390x from the list because we don't have all the required images.

I'll strip out s390x. Will we have automated CI tests by the 1.8 release, or is the new goal just to have conformance tests running manually for these architectures by then?

I doubt about having automated CI tests for all the architectures by 1.8 release because we need a different approach and hardware to run these tests on all different architectures.

@luxas @ixdy any different opinion?

Just let me know if I should rip out the entry altogether, or modify it to say something else. I would also recommend updating the feature issue #288 if the scope or timeline has changed.

pipejakob · 2017-08-17T22:01:44Z

I've stripped out the reference to s390x per @mkumatag and rebased. I'll still squash all the commits before merging.

If there isn't any other immediate feedback, I'd prefer to just merge as-is and let people tweak as necessary after commit. Does that sound okay, @jdumars?
