resource.customizations.ignoreDifferences doesn't save configuration #634
Description
Describe the bug
I have an argocd application that contains a following configmap:
kind: ConfigMap
metadata:
annotations:
kubectl.kubernetes.io/last-applied-configuration: >
{"apiVersion":"v1","data":{},"kind":"ConfigMap","metadata":{"annotations":{},"labels":{"app.kubernetes.io/instance":"kubecost","config.openshift.io/inject-trusted-cabundle":"true"},"name":"ca-inject","namespace":"kubecost"}}
creationTimestamp: '2023-12-16T02:24:01Z'
labels:
app.kubernetes.io/instance: kubecost
config.openshift.io/inject-trusted-cabundle: 'true'

uid: 0955b2d6-daf1-4544-b392-926fc14b960bAs you can see cluster-network-operator/configmap_ca is managing that data field and inject openshift ca-bundle content there. Since that field is different from desired it is always out of sync. I tried to add a configuration to my ArgoCD CDR instance in these ways, but that configmap still out of sync. Also I've spotted that ArgoCD doesn't save a piece of the configuration:

This is years too late, but I just stumbled on it now and it might help someone in the future.
I think the the resource kind is incorrectly cased. I think it should be
ConfigMapinstead ofconfigmapsI use this functionality on some resources and tested with those.
This works for me:
And this doesn't:
