[backend] Warning during kubeflow pipelines installation about deprecated `commonLabels`

[etheleon]

Environment

• How did you deploy Kubeflow Pipelines (KFP)? I deployed KFP on my standalone workstation running Ubuntu 24.04 LTS

• KFP version: 2.3.0

Steps to reproduce

Followed instructions from https://www.kubeflow.org/docs/components/pipelines/operator-guides/installation/

export PIPELINE_VERSION=2.3.0
kubectl apply -k "github.com/kubeflow/pipelines/manifests/kustomize/cluster-scoped-resources?ref=$PIPELINE_VERSION"
kubectl wait --for condition=established --timeout=60s crd/applications.app.k8s.io
kubectl apply -k "github.com/kubeflow/pipelines/manifests/kustomize/env/dev?ref=$PIPELINE_VERSION"

When applying the last command i got a couple of commonLabels is deprecated warning.

kubectl apply -k "github.com/kubeflow/pipelines/manifests/kustomize/env/dev?ref=$PIPELINE_VERSION"

I would love to work on this could anyone guide me?

Hey @etheleon this looks like the kustomize manifest files need to be updated, you can grep for all occurrences of these in the manifests folder example here:

# from manifests/ folder
$ grep -r "commonLabels" . 
./kustomize/base/cache-deployer/kustomization.yaml:commonLabels:
./kustomize/base/cache/kustomization.yaml:commonLabels:
./kustomize/base/installs/multi-user/cache/kustomization.yaml:commonLabels:

Hi @HumairAK, there's multiple resources are impacted by this change, should i submit this as a single PR?

How can I test this?

Also I've created a draft PR https://github.com/kubeflow/pipelines/pull/11289

@HumairAK, the list you provided, manifests meant for the openshift environment cant be found on the master branch anymore

[HumairAK]

I was probably on a separate fork, so I wouldn't use my list as the source of truth here, rather just run the same command in the kubeflow master branch

Hi @HumairAK, there's multiple resources are impacted by this change, should i submit this as a single PR?

that would be ideal, yes, I've added this to 2.4 milestone, so I'll try get some eyes on this, thank you!
