- Around line 329-343: Skip backend reconciliation when the namespace is already
marked for deletion, because ensureDefaultArgoCDInstanceDoesntExist may leave it
in Terminating and the later Client.Get can still succeed. In the reconcile path
that calls ensureDefaultArgoCDInstanceDoesntExist, inspect the Namespace object
returned by Client.Get and only call reconcileBackend when it exists and has no
DeletionTimestamp; otherwise return without reconciling. Use the existing
symbols ensureDefaultArgoCDInstanceDoesntExist, Client.Get, and reconcileBackend
to keep the fix localized.
- Around line 309-319: Guard the version parsing in gitopsservice_controller.go
before indexing Segments() in the OCP version comparison logic. In the code
around realVersion/startVersion and the
version.NewVersion(dynamicPluginStartOCPVersion) path, check that each slice has
at least 2 elements before reading index 1, and handle shorter versions safely
by returning early or skipping the comparison. This prevents an
index-out-of-range panic when dynamicPluginStartOCPVersion is a single-segment
version like "4".

This will also disable console-plugin deployment, is that expected ? |
yes, this is expected because the console plugin resources (Service, Deployment, ConfigMap) are deployed into the openshift-gitops namespace. When DISABLE_DEFAULT_ARGOCD_INSTANCE=true, the namespace does not exist and plugin resources have nowhere to be deployed, please correct me if I have understood this incorrectly. |

FYI - @anandf @keithchong |
|
@keithchong, any comments? Are you ok with such behavior? |
|
IMO, this should go in after #1231 |
|
I agree with Oliver that this should go in after #1231. I am unsure why the console plugin should be disabled if the flag is set to true. In 1231, the console plugin resources are created in the operator's namespace. So whether DISABLE_DEFAULT_ARGOCD_INSTANCE is true or false, that should not impact that? eg. the plugin resources will still be created. It's just that we won't have the default Argo CD instance. The console plugin should still exist/be enabled/work regardless. |
@keithchong yes after #1231 gets merged the console plugin resources will be created in the operator's namespace. I will make necessary changes in this PR once #1231 gets merged |

#1231 got merged, now working on this |

We probably don't want to delete the namespace itself when DISABLE_DEFAULT_ARGOCD_INSTANCE is true, there might be other stuff in there that was created outside the operator.
We should only make sure to delete the resources that we created within the namespace, and it's up to the user to clean up any other resources in the namespace.

● 429 [correctness] ensureDefaultArgoCDInstanceDoesntExist deletes the ArgoCD CR and namespace but never removes the cluster-scoped ClusterRole/ClusterRoleBinding created for the backend ServiceAccount.

What does this PR do / why we need it:
This PR prevents the openshift-gitops namespace from being created when DISABLE_DEFAULT_ARGOCD_INSTANCE=true is set. Previously, the flag only prevented the ArgoCD instance creation but still created the namespace.
