AssociateInstancesKeyPairs

Last updated: 2024-10-22 19:32:49

    1. API Description

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

    This API is used to associate key pairs with instances.

    • If the public key of a key pair is written to the SSH configuration of the instance, users will be able to log in to the instance with the private key of the key pair.
    • If the instance is already associated with a key, the old key will become invalid.
      If you currently use a password to log in, you will no longer be able to do so after you associate the instance with a key.
    • Batch operations are supported. The maximum number of instances in each request is 100. If any instance in the request cannot be associated with a key, you will get an error code.

    A maximum of 10 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.
