Cluster Section

  • Artikkel

A cluster template file must have at least one [cluster] section with an inline name attribute. This 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 cluster definition is purely for child reference.
Autoscale Boolean Enable auto-start and stop on nodearrays
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 you would specify a value of 10. Note that MaxCount and MaxCoreCount can be used together, in which case the lower effective constraint will take effect.
MaxCoreCount Integer To ensure that the cluster never exceeds 100 cores you would specify a value of 100. Note that MaxCount and MaxCoreCount can be used together, in which case the lower effective constraint will take 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.
