You can use the REST API reservation service to obtain compute resources for vRealize Automation reservations.

Before you begin

When you create a reservation, you must provide compute resource information that corresponds to the computeResource parameter.

For example, for a vSphere, Amazon EC2, or vCloud Air reservation type schema definition, the following permissibleValues field in the compute resource output indicates if the compute resource is available and if it has any dependencies.

“permissibleValues": {"type": "dynamic","customAllowed": false, "dependencies": []} 

Procedure

Use the following command to get a compute resource.
  • Command to get a compute resource for vSphere reservation.

    curl --insecure -H "Accept:application/json" 
    -H "Authorization: Bearer $token" 
    https://$vRA/reservation-service/api/data-service/schema/Infrastructure.Reservation.Virtual.vSphere/default/computeResource/values  -d “{}”
  • Command to get a compute resource for an Amazon EC2 reservation.

    curl --insecure -H "Accept:application/json" 
    -H "Authorization: Bearer $token" 
    https://$vRA/reservation-service/api/data-service/schema/Infrastructure.Reservation.Cloud.Amazon/default/computeResource/values  -d “{}”
    Example: curl Command for a vCloud reservation
  • Command to get a compute resource for a vCloud reservation.

    curl --insecure -H "Accept:application/json" 
    -H "Authorization: Bearer $token" 
    https://$vRA/reservation-service/api/data-service/schema/Infrastructure.Reservation.Cloud.vCloud/default/computeResource/values  -d “{}”

Get a Compute Resource for the Reservation

The following sample displays JSON output for a vSphere reservation.
