describe_db_subnet_groups

RDS.Client.describe_db_subnet_groups(**kwargs)

Returns a list of DBSubnetGroup descriptions. If a DBSubnetGroupName is specified, the list will contain only the descriptions of the specified DBSubnetGroup.

Request Syntax

response = client.describe_db_subnet_groups(
    DBSubnetGroupName='string',
    Filters=[
        {
            'Name': 'string',
            'Values': [
                'string',
            ]
        },
    ],
    MaxRecords=123,
    Marker='string'
)

Parameters:

• DBSubnetGroupName (string) – The name of the DB subnet group to return details for.

• Filters (list) –

  This parameter isn’t currently supported.

  • (dict) –

    A filter name and value pair that is used to return a more specific list of results from a describe operation. Filters can be used to match a set of resources by specific criteria, such as IDs. The filters supported by a describe operation are documented with the describe operation.

    Note

    Currently, wildcards are not supported in filters.

    The following actions can be filtered:

    • DescribeDBClusterBacktracks

    • DescribeDBClusterEndpoints

    • DescribeDBClusters

    • DescribeDBInstances

    • DescribePendingMaintenanceActions

    • Name (string) – [REQUIRED]

      The name of the filter. Filter names are case-sensitive.

    • Values (list) – [REQUIRED]

      One or more filter values. Filter values are case-sensitive.

      • (string) –

• MaxRecords (integer) –

  The maximum number of records to include in the response. If more records exist than the specified MaxRecords value, a pagination token called a marker is included in the response so that you can retrieve the remaining results.

  Default: 100

  Constraints: Minimum 20, maximum 100.

• Marker (string) – An optional pagination token provided by a previous DescribeDBSubnetGroups request. If this parameter is specified, the response includes only records beyond the marker, up to the value specified by MaxRecords.

Return type:

dict

Response Structure

• (dict) –

  Contains the result of a successful invocation of the DescribeDBSubnetGroups action.

  • Marker (string) –

    An optional pagination token provided by a previous request. If this parameter is specified, the response includes only records beyond the marker, up to the value specified by MaxRecords.

  • DBSubnetGroups (list) –

    A list of DBSubnetGroup instances.

    • (dict) –

      Contains the details of an Amazon RDS DB subnet group.

      This data type is used as a response element in the DescribeDBSubnetGroups action.

      • DBSubnetGroupName (string) –

        The name of the DB subnet group.

      • DBSubnetGroupDescription (string) –

        Provides the description of the DB subnet group.

      • VpcId (string) –

        Provides the VpcId of the DB subnet group.

      • SubnetGroupStatus (string) –

        Provides the status of the DB subnet group.

      • Subnets (list) –

        Contains a list of Subnet elements.

        • (dict) –

          This data type is used as a response element for the DescribeDBSubnetGroups operation.

          • SubnetIdentifier (string) –

            The identifier of the subnet.

          • SubnetAvailabilityZone (dict) –

            Contains Availability Zone information.

            This data type is used as an element in the OrderableDBInstanceOption data type.

            • Name (string) –

              The name of the Availability Zone.

          • SubnetOutpost (dict) –

            If the subnet is associated with an Outpost, this value specifies the Outpost.

            For more information about RDS on Outposts, see Amazon RDS on Amazon Web Services Outposts in the Amazon RDS User Guide.

            • Arn (string) –

              The Amazon Resource Name (ARN) of the Outpost.

          • SubnetStatus (string) –

            The status of the subnet.

      • DBSubnetGroupArn (string) –

        The Amazon Resource Name (ARN) for the DB subnet group.
