When an Elastic Container Instance (ECI) provides long-term services, you can use reserved instances to deduct the costs. This topic describes how to use reserved instances.
- Purchase reserved instances based on your actual needs. For more information, see Purchase reserved instances.
- You can view and manage your reserved instances. For more information, see Split a reserved instance.
A reserved instance is only applicable when you create an ECI based on a specified ECS instance type. For more information, see Specify ECS instance types to create an ECI.
Add the following annotations to the
templte of a pod. In this example, the reserved instance is used to buy an ecs.c5.large instance:
annotations: k8s.aliyun.com/eci-instance-type : "ecs.c5.large"# Replace the value with the actual ECS instance type in the following format: ecs. instance family. instance specification, for example, ecs.c6.3xlarge
annotationsmust be added to the
specfield of the pod. Enter the ECS specification as needed. For more information about supported ECS types, see Instance families.
