Description Erik M Jacobs 2015-10-05 13:52:24 UTC

There doesn't appear to be an option to show labels like there is with "oc env". There is no --list

As a user of OpenShift
When using the command line
I want to be able to see all the labels on an object with the "oc label" command

Right now I think the only way to do this is with "oc describe".

Upstream PR: https://github.com/kubernetes/kubernetes/pull/51971

Comment 3 Juan Vallejo 2017-10-25 20:32:17 UTC

Upstream PR has merged, marking this as UpcomingRelease, Rebase

Comment 4 Xingxing Xia 2018-01-16 03:32:18 UTC

Checked oc v3.9.0-0.19.0 `oc label -h` now has `--list`, and generally it works:
$ oc label dc/ruby-ex --list 
app=ruby-ex
$ oc label po ruby-ex-2-649cc --list
app=ruby-ex
deployment=ruby-ex-2
deploymentconfig=ruby-ex

However, it is not perfect for multiple resources:
$ oc label dc ruby-ex aosqe-ho --list
app=ruby-ex
app=aosqe-ho

It should add preceding resource names like `oc set env --list` for multiple resources:
$ oc set env dc ruby-ex aosqe-ho --list
# deploymentconfigs ruby-ex, container ruby-ex
NEW_ENV2=new_value2
# deploymentconfigs aosqe-ho, container aosqe-ho
NEW_ENV1=new_value1

Please check

Comment 5 Juan Vallejo 2018-01-16 19:12:35 UTC

Opened upstream PR for this. Marking as upcoming release.
https://github.com/kubernetes/kubernetes/pull/58353

New output for `oc labels --list` will include the resource kind/name before each set of labels belonging to that specific resource:

$ oc label ... dc dc_one dc_two --list
Listing labels for dc/dc_one:
label1=one
Listing labels for dc/dc_two:
label2=two

Comment 7 Maciej Szulik 2019-02-21 15:56:15 UTC

oc label --list pod/name is a thing for quite a while already, moving to QA.

(In reply to Xingxing Xia from comment #4)

> app=ruby-ex
> app=aosqe-ho
This still exists in latest 3.9 oc 3.9.71 and 3.10 oc 3.10.118.

Fixed in 3.11 oc 3.11.86:
3.11/oc label dc registry-console router --list
Listing labels for DeploymentConfig.apps.openshift.io/registry-console:
 createdBy=registry-console-template
 name=registry-console
Listing labels for DeploymentConfig.apps.openshift.io/router:
 router=router

Since bug is low AND no versioned advisory attached, IMO target field can be changed.
