Spot instances may be repossessed by Tencent Cloud due to price or inventory reasons. To enable users to perform custom operations before instance repossession, we provide an API for obtaining information about repossession status via an internal metadata mechanism.

Metadata

Instance metadata refers to data relevant to an instance. It can be used for configuring or managing an operating instance. You can access and obtain instance metadata via an instance. For more information, see Instance Metadata.

Using metadata to obtain information about repossession status of a spot instance

To obtain information about the repossession status of a spot instance, you can access the metadata by using the cURL tool or an HTTP GET request.

curl metadata.tencentyun.com/latest/meta-data/spot/termination-time

• If the following information is returned, it indicates the repossession time of the spot instance.

• If the error code 404 is returned, the instance is not a spot instance or repossession has not been triggered.
