Kube-state-metrics: tags/labels missing for daemonset, deployment, and replicaset metrics

[jimmyseto]

Is this a BUG REPORT or FEATURE REQUEST?:

Uncomment only one, leave it on its own line:

/kind bug
/kind feature

What happened:
metrics for daemonset, deployment, and replicaset no longer export tags/labels

What you expected to happen:
metrics for daemonset, deployment, and replicaset to include tags/labels

How to reproduce it (as minimally and precisely as possible):
create daemonset, deployment, or replicaset. poll kube-state-metrics endpoint. look at, for example, kube_replicaset_created metrics. observe no tags/labels are attached to it.

Anything else we need to know?:
v1.9.7 does not exhibit this issue. below is a sample comparison with kube_*_created. the same behavior is observed with all daemonset, deployment, and replicaset metrics.

v2.0.0-alpha:
kube_replicaset_created 1.600788121e+09

kube_deployment_created 1.600788121e+09

kube_daemonset_created 1.600790245e+09=

kube_configmap_created{namespace="openshift-console",configmap="console-config"} 1.600780846e+09

v1.9.7:
kube_replicaset_created{namespace="openshift-console",replicaset="console-fcbd85f55"} 1.600780846e+09

kube_deployment_created{namespace="openshift-web-console",deployment="webconsole"} 1.600780806e+09

kube_daemonset_created{namespace="openshift-node",daemonset="sync"} 1.600780702e+09

kube_configmap_created{namespace="openshift-console",configmap="console-config"} 1.600780846e+

@lilic fyi. thanks.

[lilic]

@jimmyseto Thanks for the issue, can you share the deployment for kube-state-metrics itself, thanks!

@jimmyseto Thanks for the issue, can you share the deployment for kube-state-metrics itself, thanks!

@lilic i just deployed using what's in example/standard (https://github.com/kubernetes/kube-state-metrics/tree/master/examples/standard).

[jimmyseto]

just as another datapoint, using the same deployment (and simply changing the image to 1.9.7), i see the expected results.

@jimmyseto thanks, I could reproduce it locally, looking into what was causing the problem, I have a suspicion. Thank you so much for your testing and the report, its super useful! 🎉

@lilic Looks like it's a closure loop issue with the label filtering. I fix it here https://github.com/kubernetes/kube-state-metrics/pull/1041/files#diff-5ca58d412bc2ec4e34ceaa2ad2cde1eb

[Rmond]

I met same problem on v2.0.0-alpha

[lilic]

@jw-s thanks, do you mind adding that bug fix in a separate PR, as we want to backport that to the release-2.0 branch, thanks!

[jw-s]

@lilic No worries, I've raised the PR

[jimmyseto]

thanks for the quick turnaround on this, @jw-s ! verified with a manual build of the latest/greatest off the release-2.0 branch, and confirmed that this is now fixed.
