Creating and Importing an SSH Key Pair (Native OpenStack API)

Function

This interface is used to create an SSH key pair or import a public key to generate a key pair.

After an SSH key is created, download the private key to a local directory. Then, you can use this private key to log in to the BMS. To ensure BMS security, the private key can be downloaded only once. Keep it secure.

URI

POST /v2.1/{project_id}/os-keypairs

Table 1 lists the parameters.
