Hello @yujunz , The name field holds resource name (if you need to ignore the difference in one particular resource ), not group. Please try using group field instead.

[yujunz]

@alexmt I do want to ignore one particular resource.

apiVersion: apiregistration.k8s.io/v1
kind: APIService
metadata:
  annotations:
    admission-webhook.appscode.com/active: 'true'
    admission-webhook.appscode.com/status: ''
    kubectl.kubernetes.io/last-applied-configuration: >
      ...
  creationTimestamp: '2019-12-26T01:45:40Z'
  labels:
    app: kubedb
    app.kubernetes.io/instance: kubedb
    chart: kubedb-0.12.0
    heritage: Tiller
    release: kubedb
  name: v1alpha1.validators.kubedb.com

caBundle will be injected into this api service and annotates as active. These changes happens out of argocd and I want to ignore these differences.

[alexmt]

Ah, I see. I believe diff settings were not applied because group is missing. If group field is not specified it defaults to an empty string and so resource apiregistration.k8s.io/v1alpha1.validators.kubedb.com does not match. Please try following settings:

  ignoreDifferences:
  - kind: APIService
    group: apiregistration.k8s.io
    name: v1alpha1.validators.kubedb.com
    jsonPointers:
    - /spec/caBundle
    - /metadata

Now I remember. When group is missing, it defaults to the core api group.

What about specific annotation and not all annotations? I am not able to skip slashes and times ( dots) in the json pointer ( json path ) :(

@abdennour use '~1' in place of '/'.
