change label namespace

[andyxning]

Change nfd label to nfd.alpha.kubernetes.io according to Kubernetes Community #300 when in alpha phase.

How about we change nfd namespace according to nfd available phase like below:

• alpha
  • nfd.alpha.kubernetes.io
• beta
  • nfd.beta.kubernetes.io
• GA(graduate from incubator)
  • nfd.kubernetes.io

I can get to this post v1.8

I'm not totally convinced that we need to evolve the alpha names, but the pattern for beta and GA proposed here look great. Could you start a tracking issue for graduation to beta that includes the beta naming scheme? Then we can get momentum moving towards graduating this repo.

cc @balajismaniam for another opinion here

The reason for using nfd as the subdomain name as kubernetes.io in alpha, beta and GA is mainly:

• more smaller and at the same time it is also clear that it represents node-feature-discovery. Smaller labels is more friendly to ETCD.
• the unification of alpha, beta and GA is mainly to keep the subdomain clearly targeted for node-feature-discovery. Maybe it is just a placeholder for alpha.

I also suggest we add node-feature-discovery labels schema to the well-known kubernetes labels once we make an agreement on this.

I guess my concern is adding unnecessary label churn beyond what's required by alpha => beta and beta => ga. On board with picking up the convention upon move to beta. I don't think it's worthwhile to rev the naming scheme before that.

Will fire an issue to track the jobs we need to do for a beta release later.

@ConnorDoyle I have added an issue #74 and list something i think we need to do before we reach beta release. PTAL.

[balajismaniam]

I agree with @ConnorDoyle. We should not change label namespaces before graduating to beta. Moreover, moving to kubernetes.io namespace might require discussion with the community. I like the label conventions mentioned for beta and GA.

@balajismaniam Agree on moving to kubernetes.io namespace might require discussion with the community.. What about send an email to kubernetes-sig-node and cc sponsor @dchen1107 and champion @davidopp .

Closing this for now. Let's wait till beta to change this.
