Limit the ignored path to Hearth-managed flavors.
RespectIgnoreDifferences=true causes Argo CD to exclude the complete spec.resourceGroups subtree during sync. Changes to coveredResources, flavor membership, and quotas can remain unreconciled. Use only .spec.resourceGroups[0].flavors.

Argo CD AppProject clusterResourceWhitelist resource name restrictions name field
💡 Result:
In Argo CD, the name field within the AppProject clusterResourceWhitelist (and clusterResourceBlacklist) allows you to restrict permissions to specific instances of a cluster-scoped resource based on their name [1][2][3]. Key details regarding the name field include: * Glob Pattern Support: The field supports glob patterns using Go's filepath.Match syntax (e.g., team1-* to match any resource starting with team1-) [1][2][4]. * Default Behavior: If the name field is left unspecified (or set to an empty string), it defaults to matching all resources of the specified group and kind [2][3]. * Configuration Examples: * To allow only specific namespaces (e.g., those starting with team1-): yaml spec: clusterResourceWhitelist: - group: '' kind: Namespace name: team1-* * To deny specific cluster-scoped resources by name (e.g., those starting with kube-): yaml spec: clusterResourceBlacklist: - group: '' kind: Namespace name: kube-* * CLI Usage: You can also manage these restrictions using the Argo CD CLI, where the [NAME] argument is optional [5]: * argocd proj allow-cluster-resource <PROJECT> <GROUP> <KIND> [<NAME>] * argocd proj deny-cluster-resource <PROJECT> <GROUP> <KIND> [<NAME>] This functionality is particularly useful for cluster-scoped resources like Namespaces and CustomResourceDefinitions (CRDs), where you may want to grant access to specific instances rather than the entire resource type [1][6].

Restrict cluster-scoped permissions to the Fournos resource names.
The whitelist permits every Namespace, ClusterQueue, and ResourceFlavor name. The automated Application tracks main with pruning and self-healing enabled. Add name constraints for fournos-controller, psap-automation, psap-secrets, fournos-queue, and intlab-bootstrap, or isolate these resources in a separately trusted project.

Apply namespace overrides to the Intlab overlay.
When apply.sh runs with a custom namespace, oc apply -k still creates the hard-coded namespaces and ImageStream. The later commands target custom namespaces, while manifests/ocpci-sa/*.yaml remains in psap-automation. If the custom namespaces do not exist, the namespaced applies fail. If they exist, the custom workload namespace lacks fournos.dev/queue-access, so its LocalQueue is not eligible for fournos-queue and jobs can remain pending. Parameterize the overlay and OCPCI manifests consistently, or reject custom namespace overrides.

site:docs.redhat.com OpenShift GitOps 1.20 argocd.argoproj.io/managed-by openshift-gitops target namespace
💡 Result:
In Red Hat OpenShift GitOps 1.20, the argocd.argoproj.io/managed-by annotation (often applied as a label on a namespace) is used to authorize an Argo CD instance to manage resources within a specific target namespace [1][2][3]. By applying this label, you grant the Argo CD instance running in the specified namespace permissions to manage the target namespace [1][3]. Specifically, when you label a target namespace with argocd.argoproj.io/managed-by=<argocd_namespace>, the OpenShift GitOps Operator automatically creates the necessary Role and RoleBinding objects in that target namespace, effectively assigning the Argo CD components namespace-admin privileges [1][2][4]. To configure a target namespace to be managed by an Argo CD instance, run the following command: oc label namespace <target_namespace> argocd.argoproj.io/managed-by=<argocd_namespace> Where: - <target_namespace> is the namespace you intend to manage via Argo CD [1][3]. - <argocd_namespace> is the namespace where the Argo CD instance is installed (e.g., openshift-gitops) [1][5][3]. Note that this mechanism operates on namespaces within the same cluster where the GitOps Operator is running [4][6]. For multi-cluster scenarios, manual configuration of permissions is required [4][6]. Additionally, because modifying namespace labels typically requires cluster-admin privileges, this approach is primarily intended for administrators rather than as a self-service mechanism for tenants [4][6].

Add the OpenShift GitOps management label to fournos-controller.
apply.sh applies the overlay without adding this label. Add argocd.argoproj.io/managed-by: openshift-gitops so OpenShift GitOps can manage the namespaced ImageStream in this target namespace.
