URI

  • POST /v2/{project_id}/sfs/resource_instances/action

  • Parameter description

    Parameter

    Mandatory

    Type

    Description

    Specifies the project ID of the operator.

Request

  • Parameter description

    Parameter

    Mandatory

    Type

    Description

    action

    Yes

    String

    Specifies the operation identifier. Possible values are filter and count.

    Use count to query the number of share instances based on tags.

    matches

    No

    Array of matches

    Specifies the file system query field. If this parameter is left null, all shared file systems of the tenant are searched by default.

    tags

    No

    Array of tags

    Specifies the tag search field, which is a list of tags. Only shared file systems containing all the listed tags can be returned. Tags in this search criteria are in the AND relationship. Specifically, a shared file system can be searched only when it meets all the tag search criteria. In the key-values structure of each tag search condition, tag values are in the OR relationship. If the value of tags is not specified, all shared file systems meet the requirement of this tag search field. This field contains a maximum of 20 tag keys and each tag key has a maximum of 10 tag values. The tag value corresponding to each tag key can be an empty array but the structure cannot be missing. Tag keys must be unique. Tag values in a key-values structure must be unique.

    tags_any

    No

    Array of tags

    Specifies the tag search field, which is a list of tags. Shared file systems that contain any listed tag will be returned. Tags in this search criteria are in the OR relationship. Specifically, a shared file system can be searched as long as it meets one tag search condition. In the key-values structure of each tag search condition, tag values are in the OR relationship. If the value of tags_any is not specified, all shared file systems meet the requirement of this tag search field. This field contains a maximum of 20 tag keys and each tag key has a maximum of 10 tag values. The tag value corresponding to each tag key can be an empty array but the structure cannot be missing. Tag keys must be unique. Tag values in a key-values structure must be unique.

    not_tags

    No

    Array of tags

    Specifies the tag search field, which is a list of tags. Only shared file systems that contain none of the listed tags will be returned. Tags in this search criteria are in the NOR relationship. Specifically, a shared file system can be searched only when it does not meet any tag search criteria. In the key-values structure of each tag search condition, tag values are in the OR relationship. If the value of not_tags is not specified, all shared file systems meet the requirement of this tag search field. This field contains a maximum of 20 tag keys and each tag key has a maximum of 10 tag values. The tag value corresponding to each tag key can be an empty array but the structure cannot be missing. Tag keys must be unique. Tag values in a key-values structure must be unique.

    not_tags_any

    No

    Array of tags

    Specifies the tag search field, which is a list of tags. Shared file systems that do not contain any of the listed tags will be returned. Tags in this search criteria are in the NAND relationship. Specifically, a shared file system can be searched as long as it does not meet one tag search condition. In the key-values structure of each tag search condition, tag values are in the OR relationship. If the value of not_tags_any is not specified, all shared file systems meet the requirement of this tag search field. This field contains a maximum of 20 tag keys and each tag key has a maximum of 10 tag values. The tag value corresponding to each tag key can be an empty array but the structure cannot be missing. Tag keys must be unique. Tag values in a key-values structure must be unique.

    sys_tags

    No

    Array of tags

    Only the op_service permission can use this field to filter resources.

    1. Currently, TMS can invoke only one tag structure key, _sys_enterprise_project_id.

    2. Currently, key contains only one value.

    3. sys_tags and tenant tag filtering conditions (tags, tags_any, not_tags, and not_tags_any) cannot be used at the same time.

    Important

    In the request parameters, tag search fields tags, tags_any, not_tags, and not_tags_any are optional and can be combined with each other. Such tag search fields are in the AND relationship.

  • Description of the match field

    Parameter

    Mandatory

    Type

    Description

    key

    Yes

    String

    Specifies the key. The value is fixed to resource_name.

    value

    Yes

    String

    Specifies the value. value indicates the name of a shared file system. An empty string specifies an exact match and only shared file systems whose names are empty can be queried. A non-empty string specifies a fuzzy query (case insensitive). The value can contain a maximum of 255 characters.

  • Description of the tag field

    Parameter

    Mandatory

    Type

    Description

    key

    Yes

    String

    Specifies the key of the tag. A tag key can contain a maximum of 127 characters. This parameter cannot be left blank.

    values

    Yes

    Array of strings

    Lists the values. Each value can contain a maximum of 255 characters. If the value is left empty, any value is matched. The values are in the OR relationship.
