Description

Constraint

String

The private pool ID. This is the ID of the elastic guarantee service or capacity reservation service.

None

MatchCriteria

String

After the elastic guarantee service or capacity reservation service becomes effective, it generates private pool capacity for instance startup.

Valid values:

Open: Launch instances using available capacity from private pools that match your criteria. If no matching private pool capacity is available, Alibaba Cloud uses public pool resources instead. Do not set the PrivatePoolOptions.Id parameter in this mode.
Target: Launch instances using a specific private pool. If the specified private pool is unavailable, the instance launch fails. Set the PrivatePoolOptions.Id parameter in this mode.
None (default): Do not use private pool capacity. Instances launch using only public pool resources.

In any of the following scenarios, the private pool capacity option for an instance launch can only be set to None or be omitted.

Create a spot instance.
Create an ECS instance of the classic network type.
Create an ECS instance on a Dedicated Host (DDH).

Return values

Fn::GetAtt

InstanceId: The instance ID. This is a globally unique identifier generated by the system.
PrivateIp: The private IP address of a VPC-type instance.
InnerIp: The internal IP address of a classic-type instance.
