Namespace certificates API group #31887

liggitt · 2016-09-01T15:42:24Z

New API groups should follow best-practices for naming, including using DNS names within the k8s.io namespace

The certificates API group has been renamed to certificates.k8s.io

@pwittrock requesting that this be included in v1.4 milestone.

How risky is it to merge this change?

Not risky. This is a rest path change of an API that will be introduced as alpha in v1.4.

How easy is it to roll this change back?

Not hard. This is mostly a rename. Some autogenerated swagger files are touched but the change is isolated to certificates API sections of those files so there won't be merge conflicts.

What's the cost if it doesn't make the 1.4 release?

Even if we wanted to make a compatible new API version of this API, we could not. Although the API is alpha and we reserve the right to break it, we should aim to avoid this if at all possible. Without this change, all API consumers will break on upgrade from v1.4 to v1.5.

LGTM, @caesarxuchao can you make sure the api bits look fine?

caesarxuchao · 2016-09-01T20:14:29Z

I thought the decision in the sig meeting yesterday is using "kubernetes.io", not "k8s.io"? @lavalamp

liggitt · 2016-09-01T21:32:35Z

I thought the decision in the sig meeting yesterday is using "kubernetes.io", not "k8s.io"?

I didn't think there was a strong preference, but maybe I misread. For consistency with our import package (k8s.io), existing API groups (see below), and ease of use, I went with the shorter name.

existing API groups:

$ find . -name register.go | xargs -n 1 grep 'GroupName = ' | sort -u
const GroupName = ""
const GroupName = "apps"
const GroupName = "authentication.k8s.io"
const GroupName = "authorization.k8s.io"
const GroupName = "autoscaling"
const GroupName = "batch"
const GroupName = "certificates.k8s.io"
const GroupName = "componentconfig"
const GroupName = "extensions"
const GroupName = "federation"
const GroupName = "imagepolicy.k8s.io"
const GroupName = "policy"
const GroupName = "rbac.authorization.k8s.io"

lavalamp · 2016-09-01T21:42:30Z

@bgrant0607 prefers it spelled out. Not sure if that list will convince him otherwise but we can ask?

bgrant0607 · 2016-09-02T04:28:54Z

Sadly, we're not consistent. It depends on who does the API review.

We have API groups qualified with domains and those without.

We use .k8s.io in the cases above and .kubernetes.io in most annotations.

My general position for the API is to not abbreviate.
https://github.com/kubernetes/kubernetes/blob/master/docs/devel/api-conventions.md#naming-conventions

Kubernetes contributors know what K8s means, but I wouldn't expect users to. However, I don't hear people being confused by K8s as often as I used to.

In any case, my other rule is that consistency trumps correctness, so if we've used .k8s.io in other API group names but not .kubernetes.io, then stick with .k8s.io.

cc @thockin @erictune

thockin · 2016-09-02T05:37:33Z

k8s.io is supposed to be shorthand. I've intentionally used kubernetes.io for all public domains. The one exception is the go-get path, and perhaps that was a mistake.

That said, it IS shorter and I am lazy. We should use the short form in places that humans type a lot. I don't think this is one of those cases. Inconsistency annoys me, so if the ship has sailed, then consistency wins. If it's not too late, I'd still argue for "kubernetes.io".

I suppose aliasing it with "secondary" names is right out? Accept either but always emit kubernetes.io .. ?

gtank · 2016-09-02T17:40:57Z

Good change! I would also like to see this in 1.4. Consistency with the other API groups (and future norms) should be done before anyone depends on this naming scheme.

It may be a developer-centric opinion but, as someone who has typed these names frequently, I side with using .k8s.io.

mikedanese · 2016-09-02T17:45:47Z

We need to make a decision on this. Going with kubernetes.io will require migrating 4 other api groups and we should do that before v1.4. I am not opinionated.

How did you change the staging area? It looks like you manually changed it?

Anyway, the changes look fine.

yes, was manual, found it in a search for the old name

@mikedanese

Agree on being consistent. Since some of the suffixed groups existed in 1.3, switching to kubernetes.io would be pretty disruptive, not just for the 1.4 release. Without objection, I'll leave the PR as-is (and open a pick to the release-1.4 branch)

I suppose aliasing it with "secondary" names is right out? Accept either but always emit kubernetes.io .. ?

we could look into aliasing groups in future releases, but in the meantime, keeping things consistent seems ideal

bgrant0607 · 2016-09-02T19:08:03Z

I agree with .k8s.io.

Please no aliasing. It's confusing for users to see the multiple different forms in use and returning a different form than what the client expected won't work -- imagine accepting multiple apiversions but returning only 1.

we really need to get in from of the k8s.io vs kubernetes.io mess and lay
some rules, even if they are arbitrary.
