A cluster template file must have at least one [cluster] section with an inline name attribute. This section is the only required section of the file.
Examples
Conventional cluster template files have a single cluster declaration.
[cluster my-cluster]
FormLayout = SelectionPanel
Category = My Templates
CategoryOrder = 100
MaxCount = 200
Autoscale = $Autoscale
[[node defaults]]
Credentials = $Credentials
Attribute reference
| Attribute | Type | Definition |
|---|---|---|
| Abstract | Boolean | Whether the cluster definition is purely for child reference. |
| Autoscale | Boolean | Enable auto-start and stop on node arrays. |
| Category | String | Which category to display the cluster icon. |
| CategoryOrder | Integer | Install to a directory other than /opt/cycle_server. |
| FormLayout | String | "SelectionPanel" for a multi-panel display or "List" for a flat list of parameters. Defaults to "List" if not set. |
| IconUrl | URL | Link to representative icon for cluster displayed in UI. |
| MaxCount | Integer | To ensure that the cluster never exceeds 10 nodes, specify a value of 10. You can use MaxCount and MaxCoreCount together. The lower effective constraint takes effect. |
| MaxCoreCount | Integer | To ensure that the cluster never exceeds 100 cores, enter 100. You can use MaxCount and MaxCoreCount together. The lower effective constraint takes effect. |
| ParentName | String | Assume properties of abstract parent cluster in the same cluster template file unless local override. |
Note
None of the cluster attributes are required.
Subordinate objects
The cluster object has either [[node]] or [[nodearray]] as subordinate objects.
