Adding Labels and Annotations to the Application Namespace

Argo CD lets you set labels and annotations on the application namespace through the managedNamespaceMetadata field. This field is only effective if CreateNamespace=true is set in the syncOptions. Here is an example:

apiVersion: argoproj.io/v1alpha1
kind: Application
metadata:
  name: todo-app
  namespace: argocd
spec:
  destination:
    namespace: default
    server: https://kubernetes.default.svc
  project: default
  source:
    path: manifests
    repoURL: $GITLAB_URL
    targetRevision: main
