Operation description

When you call the CreateContainerGroup operation to create an elastic container instance, you can use the InstanceType parameter to specify ECS instance types that fit your specific needs. To ensure that the elastic container instance can be created, you can call the DescribeAvailableResource operation to query which ECS instance types and instance families are available in the specified region and zone before you create the elastic container instance.

Request parameters

Parameter	Type	Required	Description	Example
RegionId	string	Yes	The region ID of the ECS instance families. You can call the DescribeRegions operation to query the most recent list of regions.	cn-hangzhou
ZoneId	string	No	The zone ID of the ECS instance families. This parameter is empty by default, which indicates that ECS instance families available in all zones in the specified region are queried.	cn-hangzhou-e
DestinationResource	object	Yes	The information about the resource that you want to query.
Category	string	Yes	The type of the resource. Valid values: InstanceTypeFamily: queries instance families. If you use this parameter value, you must also specify the Value parameter. InstanceType: queries instance types. If you use this parameter value, you must also specify the Value, Cores, and Memory parameters.	InstanceTypeFamily
Value	string	No	Instance families or instance types. If you set Category to InstanceTypeFamily, you must set this parameter to instance families such as ecs.c5. If you set Category to InstanceType, you must set this parameter to instance types such as ecs.c5.large.	ecs.c6
Cores	float	No	The number of vCPUs. This parameter is available only when the Category parameter is set to InstanceType.	2
Memory	float	No	The size of the memory. Unit: GiB. This parameter is available only when the Category parameter is set to InstanceType.	4
SpotResource	object	No	The information about the preemptible instances that you want to query.
SpotStrategy	string	No	The bidding policy for the elastic container instance. Valid values: NoSpot: The instance is created as a regular pay-as-you-go instance. SpotWithPriceLimit: The instance is created as a preemptible instance with a user-defined maximum hourly price. SpotAsPriceGo: The instance is created as a preemptible instance for which the market price at the time of purchase is automatically used as the bid price. Default value: NoSpot. Note If you set this parameter to SpotWithPriceLimit or SpotAsPriceGo to query preemptible instances, you must set Category to InstanceType. You must also use the Value parameter to specify instance types, or use the Cores and Memory parameters to specify the number of vCPUs and memory size.	SpotAsPriceGo
SpotPriceLimit	double	No	The maximum hourly price of the preemptible elastic container instance. The value can be accurate to three decimal places. If you set SpotStrategy to SpotWithPriceLimit, you must specify the SpotPriceLimit parameter.	0.2
SpotDuration	integer	No	The protection period of the preemptible instance. Unit: hours. Default value: 1. The value of 0 indicates no protection period.	1
