    1. API Description

    Domain name for API request: tke.tencentcloudapi.com.

    This API is used to query one or more existing node and determine whether they can be added to a cluster.

    A maximum of 20 requests can be initiated per second for this API.

    We recommend you to use API Explorer
    Try it
    API Explorer provides a range of capabilities, including online call, signature authentication, SDK code generation, and API quick search. It enables you to view the request, response, and auto-generated examples.

    2. Input Parameters

    The following request parameter list only provides API request parameters and some common parameters. For the complete common parameter list, see Common Request Parameters.

    Parameter Name Required Type Description
    Action Yes String Common Params. The value used for this API: DescribeExistedInstances.
    Version Yes String Common Params. The value used for this API: 2018-05-25.
    Region Yes String Common Params. For more information, please see the list of regions supported by the product.
    ClusterId No String Cluster ID. Enter the ClusterId field returned when you call the DescribeClusters API (Only VPC ID obtained through ClusterId need filtering conditions. When comparing statuses, the nodes on all clusters in this region will be used for comparison. You cannot specify InstanceIds and ClusterId at the same time.)
    InstanceIds.N No Array of String Query by one or more instance ID(s). Instance ID format: ins-xxxxxxxx. (Refer to section ID.N of the API overview for this parameter's specific format.) Up to 100 instances are allowed for each request. You cannot specify InstanceIds and Filters at the same time.
    Filters.N No Array of Filter Filter condition. For fields and other information, see the DescribeInstances API. If a ClusterId has been set, then the cluster's VPC ID will be attached as a query field. In this situation, if a "vpc-id" is specified in Filter, then the specified VPC ID must be consistent with the cluster's VPC ID.
    VagueIpAddress No String Filter by instance IP (Supports both private and public IPs)
    VagueInstanceName No String Filter by instance name
    Offset No Integer Offset. Default value: 0. For more information on Offset, see the relevant section in the API Introduction.
    Limit No Integer Number of returned results. Default value: 20. Maximum value: 100. For more information on Limit, see the relevant section in the API Introduction.
    IpAddresses.N No Array of String Filter by multiple instance IPs

    3. Output Parameters

    Parameter Name Type Description
    ExistedInstanceSet Array of ExistedInstance Array of existing instance information.
    Note: This field may return null, indicating that no valid values can be obtained.
    TotalCount Integer Number of instances that match the filter condition(s).
    RequestId String The unique request ID, generated by the server, will be returned for every request (if the request fails to reach the server for other reasons, the request will not obtain a RequestId). RequestId is required for locating a problem.
