Can argocd_application labels be modified?

[ionPr]

Question

Hello,

I have deployed a set of argocd_applications and have already set some metadata.labels on them. I am currently trying to use the same code to update the labels but the changes are not picked up. If I delete the existing application and deploy it again the correct new labels are applied.
My question is, is this the expected behavior? I was not able to find any error or significant message in any of the ArgoCD pods.

Thank you!

Forgot to mention that the labels are simple strings that do not contain any special characters.

Hi @ionPr

Could you share an example TF code of your application definition?

Hi @mkilchhofer, for example the following helm application uses two labels test and foo

# Helm application
resource "argocd_application" "helm" {
  metadata {
    name      = "helm-app"
    namespace = "argocd"
    labels = {
      test = "4real"
      foo = "bar"
    }
  }

  spec {
    [..]
  }
}

The Labels are created correctly initially. But if I want the deploy/update the helm application and change or remove labels like this...

# Helm application
resource "argocd_application" "helm" {
[..]
    labels = {
      test = "ofcoursenot"
    }

...the label test is not touched/changed and the label foo is still there and will not removed.

I hope that helps for understanding. Thanks in advance for looking into.
