Addons

The Addons tab is where you turn optional ClusterControl features on or off. Starting from ClusterControl 2.5.0, the feature toggles that used to sit on the License page, Ops-Center (previously labeled Multi-controller) and Kubernetes, moved here. The License page itself now only shows license and subscription details; see ClusterControl GUI → License.

Info

Settings, including the Addons tab, is only visible to users on a team with the Change controller configuration permission (see Administration Guide → Users and Teams). Users without this permission only see Profile under Settings.

Access the Addons tab

  1. Log in to your ClusterControl GUI.
  2. Click Settings in the left sidebar.
  3. Click Addons, next to License in the Settings tab bar (Profile, Cloud storage credentials, Notification services, Certificate management, License, Addons, Diagnostics). This opens a panel listing the available feature toggles side by side as cards, or "No addons are available" if none apply to your installation.

Each addon card shows:

  • A title and a toggle switch to turn it on or off.
  • A green ✓ Enabled tag next to the title, and a highlighted border around the card, when the addon is on.
  • A short description of what the addon does.
  • A When to enable it bullet list of scenarios where it's useful.
  • A status line in the bottom-left corner (for example, Single-controller mode · local for Ops-Center when it's off).
  • A Learn more link in the bottom-right corner, pointing to that addon's documentation.

Ops-Center

Manage several ClusterControl controllers from one console. Ops-Center gives you a single pane of glass to monitor and operate every controller, cluster and node.

Use it when:

  • You run more than one ClusterControl controller, for example separate prod, staging or per-region installations, and want to manage them from one place.
  • Your fleet grows beyond ~1000 nodes and you need to scale out horizontally across several CMON controllers.
  • You want centralized monitoring with the ability to switch between controllers for targeted operations.

Enable Ops-Center

  1. Log in to your ClusterControl GUI → Settings → Addons.
  2. Toggle on Ops-Center. This opens the Enable Ops-Center wizard.
  3. Step 1, About: review the feature summary and, optionally, follow Learn more about how Ops-Center works to read further. Click Continue.
  4. Step 2, Set root user: enter a Root username and Root user password (email is optional). This root user is used exclusively when managing CMON Controllers, as an extra layer of security. Confirm the password, then click Enable.
  5. The page reloads in multi-controller mode. You can now register additional controllers.

Disable Ops-Center

Disabling Ops-Center switches the console back to single-controller mode. Since more than one controller may be registered while Ops-Center is active, ClusterControl needs you to pick which one of the registered controllers stays as the single active controller.

  1. Log in to your ClusterControl GUI → Settings → Addons.
  2. Toggle off Ops-Center. This opens the Disable Ops-Center dialog: "This switches the console to single-controller mode. The general overview across all controllers will no longer be available, and you'll work only with the controller you select below. The page will reload after the operation is complete. You can re-enable Ops-Center later."
  3. A warning notes that the Ops-Center root user is no longer needed and will be deleted.
  4. Under Controller to keep, choose the controller that should remain as the single active controller. This field is required.
  5. If more than one controller is registered, an additional checkbox appears: Remove the other controllers from the configuration. Leave it unchecked to keep the other controllers on record (so you can re-enable Ops-Center later without re-adding them), or check it to remove them now.
  6. Click Disable. The page reloads in single-controller mode, pointed at the controller you picked.

Kubernetes

Deploy and manage Kubernetes-based database clusters using database operators, alongside your traditional clusters.

Use it when:

  • Your infrastructure runs on Kubernetes and you want to operate databases as native cluster resources.
  • You want database operators to automate deployment, scaling and recovery on K8s.
  • You need to manage Kubernetes-based database clusters from the same console as the rest of your fleet.
  1. Log in to your ClusterControl GUI → Settings → Addons.
  2. Toggle Kubernetes on or off, then confirm in the dialog that appears. The page reloads after the operation completes.
  3. When enabled, the Kubernetes entry appears in the left sidebar. When disabled, it is hidden.

Info

Disabling Kubernetes does not remove any existing Kubernetes clusters; it only hides the Kubernetes options in the UI. To stop the underlying Kubernetes services, do so manually.
