Orphaned Resources Monitoring

Orphaned Kubernetes resource is a top-level namespaced resource which does not belong to any Argo CD Application. The Orphaned Resources Monitoring feature allows detecting orphaned resources, generate a warning and inspect/remove resources using Argo CD UI.

The Orphaned Resources monitoring is enabled in Project settings. Once the feature is enabled each project application which target namespace has orphaned resource will get a warning condition. The orphaned resources can be located using the application details page:

orphaned resources

Before enabling feature you might consider disabling warning. In this case application users are going to see orphaned resources in the UI but application is won’t get a warning condition.

Exceptions

Not every resource in the Kubernetes cluster is controlled by the end user. Following resources are never considered as orphaned:

  • Namespaced resources denied in the project. Usually, such resources are managed by cluster administrators and not supposed to be modified by namespace user.
  • ServiceAccount with name default ( and corresponding auto-generated ServiceAccountToken ).
  • Service with name kubernetes in the default namespace.
  • ConfigMap with name kube-root-ca.crt in all namespaces.
