AssociateInstancesKeyPairs

Last updated: 2020-10-22 16:49:15

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.

Note: This API supports Finance regions. If the common parameter Region is a Finance region, a domain name with the Finance region needs to be specified, for example: cvm.ap-shanghai-fsi.tencentcloudapi.com
