Key Pair
Create an key-pair
Individual users can create 500 key pairs in the region by default (sum of created and imported key pairs). The created key pair can be embedded into the instance to log in to the virtual machine remotely:
public static void createKeypair(BccClient bccClient, String keyName, String keyDes) {
KeypairCreateRequest keypairCreateRequest = new KeypairCreateRequest();
// Set a key name
keypairCreateRequest.setName(keyName);
// Set key descriptions
keypairCreateRequest.setDescription(keyDes);
bccClient.createKeypair(keypairCreateRequest);
}Import a Key Pair
It is used for users to import the created key pair:
public static void importKeypair(BccClient bccClient, String keyName, String keyDes, String publicKey) {
KeypairImportRequest keypairImportRequest = new KeypairImportRequest();
// Import key names
keypairImportRequest.setName(keyName);
// Add descriptions
keypairImportRequest.setDescription(keyDes);
// Public key content
keypairImportRequest.setPublicKey(publickey);
bccClient.importKeypair(keypairImportRequest);
}Query the Key Pair Details
It is used to query the single key pair details:
public static void keypairDetail(BccClient bccClient, String keypairId) {
KeypairIDetailRequest keypairDetailRequest = new KeypairDetailRequest();
// Key Name ID
keypairDetailRequest.setKeypairId(keypairId);
KeypairDetailResponse keypairDetailResponse = bccClient.keypairDetail(keypairDetailRequest);
}Bind a Key Pair
It is used to bind the selected key pair (single key pair only) to the selected virtual machine (multiple virtual machines supported). At present, one virtual machine can only bind a key pair:
public static void attachKeypair(BccClient bccClient, String keypairId, String instanceIds) {
KeypairAttachRequest keypairAttachRequest = new KeypairAttachRequest();
// Bound a key ID
keypairAttachRequest.setKeypairId(keypairId);
// Instance
keypairAttachRequest.setaddInstance(instanceIds);
bccClient.attachKeypair(keypairAttachRequest);
}Unbind a Key Pair
It is used to unbind the bound key pairs from the selected virtual machine. This operation is only applicable for the virtual machine with the Linux system, and the selected virtual machine must be in the Running or Stopped status:
public static void detachKeypair(BccClient bccClient, String keypairId, String instanceIds) {
KeypairDetachRequest keypairDetachRequest = new KeypairDetachRequest();
// Bound a key ID
keypairDetachRequest.setKeypairId(keypairId);
// Instance
keypairDetachRequest.setaddInstance(instanceIds);
bccClient.detachKeypair(keypairDetachRequest);
}Delete a Key Pair
It is used to delete a key pair. The key bound with the virtual machine can not be deleted:
public static void deleteKeypair(BccClient bccClient, String keypairId) {
KeypairDeleteRequest keypairDeleteRequest = new KeypairDeleteRequest();
// Delete a key ID
keypairDeleteRequest.setKeypairId(keypairId);
bccClient.deleteKeypair(keypairDeleteRequest);
}
