    min_ram

    No

    Integer

    Specifies the minimum memory size (MB) required for running the image. The parameter value depends on ECS specifications. The default value is 0.

    min_disk

    No

    Integer

    Specifies the minimum disk space (GB) required for running the image. The value ranges from 1 GB to 1,024 GB.
