Hub Mode
The Hub Mode page turns a standalone AdminBolt panel into a multi-server hub that orchestrates other AdminBolt panels through their REST API.
Overview
URL: /admin/hub-settings - under System → Hub Mode
Run this panel as a fleet hub orchestrating other AdminBolt panels via their REST API.
When Hub Mode is enabled, the panel keeps doing its own work and additionally manages the other servers:
When enabled, the Nodes section manages a fleet of servers, each running its own full AdminBolt panel. Customers keep logging into their own server's panel - the hub adds fleet-wide visibility, installation and orchestration.
For the bigger picture and the standalone/hub/node distinction, see Hub.
Settings
| Field | Description |
|---|---|
| Enable hub mode | Toggle that turns the panel into a hub. Unlocks the hub dashboard, node management, and the DNS cluster. Off by default. |
| Hub display name | A friendly name for the hub (for example, EU Production). |
| Minimum node panel version | The lowest panel version a node may run. Nodes below this version are flagged and blocked from migrations. Leave empty to require the hub's own version. |
Click Save to apply the configuration.
What happens after enabling
Turning on Enable hub mode reveals the multi-server management sections that are hidden on a standalone panel:
- the hub dashboard,
- node management (the Nodes section),
- the DNS cluster.
These sections become useful once nodes are connected to the hub. Until at least one node is connected, they are available but empty.
Note: The minimum node panel version gates migrations: a node running an older panel is flagged and cannot be migrated to until it is upgraded.
