Creating a BMS (Native OpenStack API)

Function

This interface is used to create a BMS.

Constraints

This interface cannot be used to create BMSs in batches.
When you create a BMS using an image that supports Cloud-Init or Cloudbase-Init, only parameter key_name can be configured. (Parameter adminPass is invalid.) The password of a Linux BMS can be injected only using parameter user_data. The password of a Windows BMS can be injected only using metadata admin_pass.
When you create a BMS using an image that does not support Cloud-Init or Cloudbase-Init, both parameters adminPass and key_name are invalid. You need to use the password or certificate of the image to log in to the BMS.
File injection is not supported.
BMS creation from a system volume is not supported.
Parameter port in the three network parameters (port, uuid, and fixed_ip) has the highest priority. If parameter fixed_ip is set, you must specify the UUID.
After a BMS is created, it is recommended that you attach the __type_baremetal tag to the BMS. This tag specifies that the created server is a BMS. Otherwise, the BMS may not be displayed in the BMS list on the management console.
A BMS can have a maximum of two VPCs, in which case the first VPC will be used by the primary NIC.

URI

POST /v2.1/{project_id}/servers

Table 1 lists the parameters.

**Table 1** Parameter description
Parameter	Mandatory	Description
project_id	Yes	Specifies the project ID.

Request Parameters

Parameter	Mandatory	Type	Description
server	Yes	Object	Specifies the BMS information, see Table 2.

**Table 2** **server** field data structure description
Parameter	Mandatory	Type	Description
imageRef	Yes	String	Specifies the ID of the image used by the BMS or the image resource uniform resource locator (URL). Example image ID: 3b8d6fef-af77-42ab-b8b7-5a7f0f0af8f2 Example image URL: http://glance.openstack.example.com/images/3b8d6fef-af77-42ab-b8b7-5a7f0f0af8f2 NOTE: BMSs using certain flavors do not support all public images provided by the cloud service platform. To obtain the images supported by a BMS flavor, log in to the management console, view the images displayed on the Create ECS page, and obtain the image IDs on the Image Management Service page. If the creation fails, modify the parameter settings.
flavorRef	Yes	String	Specifies the ID or URL of the flavor used by the BMS.
name	Yes	String	Specifies the BMS name. It contains a maximum of 255 characters and cannot be left blank.
metadata	No	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, text files, and .gzip files can be injected. The content to be injected cannot be greater than 32 KB in size. The content to be injected must be encoded with base64.
adminPass	No	String	Specifies the initial login password of the BMS administrator account. This parameter is invalid for a Linux BMS. The administrator account of a Windows BMS is Administrator. Password complexity requirements: The password contains 8 to 26 characters. The password must contain at least three of the following character types: uppercase letters, lowercase letters, digits, and special characters (!@$%^-_=+[{}]:,./?). The password cannot contain the username or the username in reverse. The Windows BMS password cannot contain the username, the username in reverse order, or more than two consecutive characters in the username. Note: If this parameter is not specified, a random password will be generated. Special characters: !@$%^-_=+[{}]:,./?
security_groups	No	Array of objects	Specifies the security group of a BMS. The default value is default. This parameter is valid when you specify parameter network. You are not allowed to specify multiple security groups. For details, see Table 4.
networks	Yes	Array of objects	Specifies the BMS NICs. For details, see Table 5. You can specify a maximum of four networks for a BMS, including two VXLAN networks and two GENEVE networks. The first network in the parameter must be a VXLAN network. The network is used as by the primary NIC of the BMS. If multiple groups of network parameters are specified, ensure that the parameters of each group belong to the same VPC.
key_name	No	String	Specifies the name of a key pair. This is an extended attribute.
availability_zone	Yes	String	Specifies information about the AZ to which the BMS belongs. You are not allowed to specify host information.

**Table 3** **metadata** field data structure description
Parameter	Mandatory	Type	Description
User-defined field key and value pair	No	String	Specifies the key and value pair of the metadata. Each key or value contains a maximum of 255 characters.

**Table 4** **security_groups** field data structure description
Parameter	Mandatory	Type	Description
name	Yes	String	Specifies the name of the security group to which the BMS belongs.

**Table 5** **networks** field data structure description
Parameter	Mandatory	Type	Description
port	No	String	Specifies the UUID of the network port.
uuid	No	String	Specifies the network UUID.
fixed_ip	No	String	Specifies the fixed IP address.

Response Parameters

Parameter	Type	Description
server	Object	Specifies the BMS information. For details, see Table 6.

**Table 6** **server** field data structure description
Parameter	Type	Description
security_groups	Array of objects	Specifies information about the BMS security group. For details, see Table 7.
OS-DCF:diskConfig	String	Specifies the disk configuration. The value can be: MANUAL: The API uses the partitioning scheme in the image and the file system to create a BMS. If the target flavor has a large disk, the API does not partition the remaining disk space. AUTO: The API uses a single partition with the same size as the disk of the target flavor to create a BMS. The API automatically adjusts the file system to adapt to the entire partition.
id	String	Specifies the BMS ID.
links	Array of objects	Specifies the shortcut links of the BMS. For details, see Table 8.
adminPass	String	Specifies the initial login password of the BMS administrator account.

**Table 7** **security_groups** field data structure description
Parameter	Type	Description
name	String	Specifies the name of the security group to which the BMS belongs.

**Table 8** **links** field data structure description
Parameter	Type	Description
rel	String	Specifies the shortcut link marker name. The value can be: self: resource link that contains the version number. It is used when immediate tracing is required. bookmark: resource link that can be stored for a long time.
href	String	Specifies the corresponding shortcut link.
