# auto-tracks and loads ArgoCD projects

# if projects managed like this were manually precreated it may result in a stuck spinning state in the 'projects' app tree view waiting to delete project state
# - to clear this you'd have to delete the project which may require deleting the apps, which may require disabling argocd app auto-sync, apps auto-sync,
#   deleting all apps in the project (watch out none have finalizers to cascading delete your deployments), and then kubectl delete appproject $project -n argocd

# shows secrets and non-managed appprojects in argocd namespace as orphans, but does not remove them when pruning as they were never managed by this app
