Creating BMSs

Function

This API is used to create one or more BMSs.

Background for Setting the Login Authentication Mode

Logging in to a BMS can be authenticated using either a key pair or password. For security purposes, you are advised to use key pair authentication.

  • Key pair

    A key pair is used for BMS login authentication.

    Method of calling APIs: Use the key_name field to specify the key file used for logging in to the BMS. For details about how to use the key_name field, see Table 2.

  • Password

    If you choose the initial password for authentication in a BMS, you can log in to a BMS using the username and its initial password. The initial password of user root is used for authentication in Linux.

    Methods of calling APIs:

    • Method 1 (recommended): Use the adminPass field to specify the initial login password of the specified administrator account. For details about how to use the adminPass field, see Table 2.

      Note

      For Linux BMSs with Cloud-Init, if field user_data is specified, field adminPass is invalid.

    • Method 2:

      • For Linux BMSs with Cloud-Init, use the user_data field to inject data. For details, see Table 2.

    Note

    Public images contain Cloud-Init or Cloudbase-Init by default. For private images, you need to check whether Cloud-Init or Cloudbase-Init is installed.

Constraints

  • File injection is not supported.

URI

POST /v1/{project_id}/baremetalservers

Table 1 lists the parameters.

Object

Specifies BMS information. For details, see Table 2.

Table 2 server field data structure description

Parameter

Mandatory

Type

Description

imageRef

Yes

String

Specifies the image ID or image resource URL used for creating the BMS. The ID is in the format of a Universally Unique Identifier (UUID).

You can obtain the image ID from the IMS console or by following the instructions in "Querying Images" in Image Management Service API Reference.

When using an API to query images, you can add the field ?virtual_env_type=Ironic to filter BMS images.

flavorRef

Yes

String

Specifies the flavor ID of the BMS. The format is physical.x.x.

You can obtain the flavor ID from the BMS console or using the Querying Details About Flavors and Extended Flavor Information API.

name

Yes

String

Specifies the BMS name.

Value range:

  • The value can contain a maximum of 63 characters consisting of letters (case-insensitive), digits, underscores (_), hyphens (-), and periods (.).

  • If more than one BMS is to be created, tags similar to -0000 will be automatically added to the end of the BMS names during the creation. In this case, the BMS name contains 1 to 58 characters.

metadata

Yes

Object

Specifies the BMS metadata. The maximum size for both the metadata key and value is 255 characters. For details, see Table 3.

user_data

No

String

Specifies the user data to be injected during the BMS creation. Text can be injected.

Constraints:

  • The content to be injected must be encoded with base64. The maximum size of the content to be injected (before encoding) is 32 KB.

  • If key_name is not specified, the password of user root for logging in to the BMS will be injected by default.

Password complexity requirements:

  • Contains 8 to 26 characters.

  • Contains at least three of the following character types: uppercase letters, lowercase letters, digits, and special characters !@$%^-_=+[{}]:,./?

An example is as follows:

  • Use a plaintext password (risky in security), for example, cloud.1234.

    #!/bin/bash
echo 'root:Cloud.1234' | chpasswd ;

  • Use a password.

    #!/bin/bash
echo 'root:$6$V6azyeLwcD3CHlpY$BN3VVq18fmCkj66B4zdHLWevqcxlig' | chpasswd -e

where, $6$V6azyeLwcD3CHlpY$BN3VVq18fmCkj66B4zdHLWevqcxlig is the ciphertext password, which can be generated as follows:

  1. Generate an encrypted salt value.

    [root@test linux]# python -c "import crypt, getpass, pwd;print crypt.mksalt()"
$6$V6azyeLwcD3CHlpY

  2. Generate a ciphertext password based on the salt value.

    [root@test linux]# python -c "import crypt, getpass, pwd;print crypt.crypt('Cloud.1234','\$6\$V6azyeLwcD3CHlpY')"
 $6$V6azyeLwcD3CHlpY$BN3VVq18fmCkj66B4zdHLWevqcxlig
