A terminating Argo CD managed namespace blocks the creation of roles and other configuration of other managed namespaces, This issue is now fixed using this JIRA.

GITOPS Sprint 224
This bug occurs when you are using namespace-scoped Argo CD via OpenShift GitOps (e.g. using 'argocd.argoproj.io/managed-by' label on Namespaces).
If you have a managed namespace with the 'argocd.argoproj.io/managed-by' label, and that Namespace is in the process of being deleted ('Terminating'), it prevents any other managed Namespace from being created.
This is likely due to this error reported in the GitOps Operator logs (in 'openshift-operators'):

This bug occurs because the argocd-operator code should not be creating managed role/rolebindings in Namespaces that are in 'Terminating' state.
Reproduced with public OpenShift GitOps v1.6.0 release.
Steps to reproduce:
Prerequisite:
- Ensure OpenShift GitOps is installed onto cluster (for example, a cluster bot cluster)
1) Install namespace-scoped Argo CD:
kubectl create ns gitops-service-argocd kubectl apply -f https://raw.githubusercontent.com/redhat-appstudio/infra-deployments/main/components/gitops/staging/argo-cd.yaml kubectl apply -f https://raw.githubusercontent.com/redhat-appstudio/infra-deployments/main/components/gitops/staging/allow-argocd-to-manage.yaml
2) Create a Namespace managed by Argo CD.
apiVersion: v1
kind: Namespace
metadata:
name: jane
labels:
argocd.argoproj.io/managed-by: gitops-service-argocd
3) Create 'ConfigMap' with a finalizer, in Namespace.
apiVersion: v1
kind: ConfigMap
metadata:
name: my-config-map-2
namespace: jane
finalizers:
- some.random/finalizer
data: {}
4) Delete the 'Namespace', putting it into 'Terminating' state. The Namespace will never finish deleting, due to the finalizer on the 'ConfigMap'.
kubectl delete namespace jane
5) Finally, attempt to create a new managed 'Namespace'
apiVersion: v1
kind: Namespace
metadata:
name: john
labels:
argocd.argoproj.io/managed-by: gitops-service-argocd
The 'john' Namespace never becomes managed by Argo CD: the Argo CD RoleBinding SHOULD be created (that gives Argo CD access to the 'john' namespace) is never created.
Likewise, if you attempt to deploy into the 'john' Namespace using an Argo CD Application, the Application status field will show an error like:
'Namespace "e2e-test-bktg" for (...) "build-suite-test-component-git-source-sbfh" is not managed'
(because the OpenShift GitOps operator has not created the RoleBinding that allows Argo CD to target this namespace)
