ApplicationSet syncPolicy setting is not working

[helloworld113]

I am use ApplicationSet to autocreate app, and the under is my syncPolicy, I have setting prune: false and selfHeal: false but it not work, when I change rescoure in living cluster by manual It also selfHeal ，I want stop selfHeal is anyone can help me？thanks

spec:
  syncPolicy:
    automated:
      prune: false
      selfHeal: false

I have read doc from auto-sync https://argo-cd.readthedocs.io/en/stable/user-guide/auto_sync/

[helloworld113]

the docs： By default (and as a safety mechanism), automated sync will not delete resources when Argo CD detects the resource is no longer defined in Git
my argocd：when I delete defined in Git the cluster resouces is delete. i dont want delete is

the docs: By default, changes that are made to the live cluster will not trigger automated sync.
my argocd : when i change in live cluster and then is trigger automated sync to selfHeal. i dont want selfHeal.

ApplicationSet setting:

spec:
  syncPolicy:
    automated:
      prune: false
      selfHeal: false

Hi @helloworld113, as per our docs here:

Prevent an Application's child resources from being modified¶
Changes made to the ApplicationSet will propagate to the Applications managed by the ApplicationSet, and then Argo CD will propagate the Application changes to the underlying cluster resources (as per Argo CD Integration).

The propagation of Application changes to the cluster is managed by the automated sync settings, which are referenced in the ApplicationSet template field:

spec.template.syncPolicy.automated: If enabled, changes to Applications will automatically propagate to the cluster resources of the cluster.
Unset this within the ApplicationSet template to 'pause' updates to cluster resources managed by the Application resource.
spec.template.syncPolicy.automated.prune: By default, Automated sync will not delete resources when Argo CD detects the resource is no longer defined in Git.
For extra safety, set this to false to prevent unexpected changes to the backing Git repository from affecting cluster resources.

if you are using applicationSet you might want to edit the applicationSet spec.template.syncPolicy instead of the actual application.

However, in upcoming 2.7 release there will be this feature that will allow you to configure annotations that are preserved by the AppSet. Please see the unreleased 2.7 documentation on this for how it will work.

If this answer satisfies your use case, please go ahead and close the discussion :) Thanks!

thanks for you reply, as you said

Unset this within the ApplicationSet template to 'pause' updates to cluster resources managed by the Application resource.
spec.template.syncPolicy.automated.prune: By default, Automated sync will not delete resources when Argo CD detects the resource is no longer defined in Git.

this is my config, but when i remove resource from git and live cluster remove also.

  template:
    metadata:
      name: '{{path.basename}}'
    spec:
      destination:
        namespace: '{{path[0]}}'
        server: '{{server}}'
      project: watch-prod
      source:
        path: '{{path}}'
        repoURL: 'http://xx.git'
        targetRevision: HEAD
      syncPolicy:
        automated:
          prune: false
          selfHeal: false

Hopefully I'm understanding your issue correctly (and I apologize if I'm not)... could you try setting .syncPolicy.preserveResourcesOnDeletion to true in the ApplicationSet? I'm looking at this in the docs and wondering if that's the issue you're facing https://argo-cd.readthedocs.io/en/stable/operator-manual/applicationset/Application-Deletion/

[helloworld113]

Much appreciated. yea, I have try is before, such as

      syncPolicy:
        preserveResourcesOnDeletion: true
        automated:
          allowEmpty: true
          prune: false

I edit is online thouth cloud, may be use apply but it seem not to save to k8s. is means i should rebuild the ApplicationSet resouces ?

[helloworld113]

this is the error :

<nil>: Invalid value: "The edited file failed validation": ValidationError(ApplicationSet.spec.template.spec.syncPolicy): unknown field "preserveResourcesOnDeletion" in io.argoproj.v1alpha1.ApplicationSet.spec.template.spec.syncPolicy

[helloworld113]

I have did it, the syncPolicy not in template.

apiVersion: argoproj.io/v1alpha1
kind: ApplicationSet
metadata:
  name: xx-applicationset
  namespace: argocd
spec:
  generators:
  - git:
      directories:
      - path: watch-ns/*
      - exclude: true
        path: donotdeploy
      repoURL: http://xxx.git
      revision: HEAD
  syncPolicy:
    preserveResourcesOnDeletion: true
  template:
    metadata:
      name: '{{path.basename}}'
    spec:
      destination:
        namespace: '{{path[0]}}'
        server: https://kubernetes.default.svc
      project: xx
      source:
        path: '{{path}}'
        repoURL: http://xx.git
        targetRevision: HEAD
      syncPolicy:
        automated:
          allowEmpty: true
          prune: false

We are on v2.12.7+4d70c51, all seeing the same problem.
Is that still a know issue?
Thx!
