This will use the `global-operators` `OperatorGroup` that is created by default in the `openshift-operators` namespace. This `OperatorGroup` will watch all namespaces in the cluster, and the operator will be able to manage resources across all namespaces.

## Release channels

Currently, the only release channel available to install the operator is `stable`, which contains supported releases of the operator. This is controlled by the `channel` field in the `Subscription` object.
We maintain support across a variety of OpenShift channels to ensure compatibility with different release schedules and stability requirements. Below, you will find an overview of the specific OpenShift channels we support.

| Channel | Supported OpenShift Versions | Description | Latest Image |
|---------|------------------------------|-------------|--------------|
| `stable` | 4.19, 4.18, 4.17, 4.16 | Points to the latest stable version of the operator. This channel may span multiple major versions. **This is the recommended option.** | `mariadb-enterprise-operator:25.8.1-1` |
| `stable-v25.10` | 4.19, 4.18, 4.17, 4.16 | v25.10.x is an LTS release. This channel points to the latest **patch** release of 25.10. Use this if you require version pinning to a stable version of the operator without necessarily looking for newer features. | `mariadb-enterprise-operator:25.10.0` |

An example Subscription would look like this:

```yaml
apiVersion: operators.coreos.com/v1alpha1
kind: Subscription
metadata:
name: mariadb-enterprise-operator
namespace: openshift-operators
spec:
channel: stable # Change this to the actual channel you want
installPlanApproval: Automatic
name: mariadb-enterprise-operator
source: certified-operators
sourceNamespace: openshift-marketplace
```
