Description:
  en: 'Schedule to stop the ECS instances, applicable to scenarios where ECS instances need to be stopped at scheduled times, such as automatically stopping development or test environments to save costs. During configuration, users need to provide the following required parameter information: Region ID (regionId), which specifies the region of the ECS instances to be operated on, Cron Expression (cron), which defines the schedule for the task, and Target Instances (targets), which defines the specific ECS instances to be operated on. Upon execution, the template will stop the ECS instances according to the configured schedule.'
