Disable argocd from automatically adding labels to configmap.

[ghost]

I use Kustomization build
When Kustomization builds, the common base configmap will be automatically added to labels, which will cause another app outofsync

k8s yaml

Two different deploy will reference the same configmap.

I created two apps in argocd.
When I deploy one of the apps synchronously, the other app gets outofsync.

The reason for outofsync is that argocd automatically adds labels.

I've searched a lot, github, argocd website but haven't found out how to disable.

Finally found a way to ignore labels.

But this one still has the SharedResourceWarning

apiVersion: v1
kind: ConfigMap
metadata:
  labels:
    app.kubernetes.io/name: argocd-cm
    app.kubernetes.io/part-of: argocd
  name: argocd-cm
  namespace: argocd
data:
  resource.customizations.ignoreDifferences.all: |
    managedFieldsManagers:
    - kube-controller-manager
    jsonPointers:
    - /metadata/labels/app.kubernetes.io~1instance

Hi,
I was struggling with the same issue.
Trying to use just one configmap file for several deployments.
and I solved it following your advice. Thanks.

I also found out, we could just set the options on ArgoCD App.
(https://argo-cd.readthedocs.io/en/stable/user-guide/diffing/)

I just added under 'spec' parts like below.

  ignoreDifferences:
  - group: '*'
    jsonPointers:
    - /metadata/labels
    kind: ConfigMap

and boom!
(However, warning is still appears on the top right 😂)
Thank you again.
